Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of the vulnerabilities disclosed in this advisory. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. Refer to the "Software Version and Fixes" section for specific information on vulnerable versions. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if the following conditions are satisfied: * The device has interfaces with IPv6 addresses * System logging is enabled (command logging enable) * The device is configured in any way to generate system log message 302015 (refer to the following examples) System log message 302015 has a default severity level of 6 (informational) so, assuming that the system administrator has not changed this default severity level, the vulnerability can be triggered if the device is logging to any destination at level 6 or level 7 (debug). As an example, the following configuration is vulnerable: logging enable ! logging console informational logging buffered informational [...] Using a custom message list (via the logging list command) that includes system log message 302015, either by severity or by explicitly including the message ID, is also a vulnerable configuration. For example, the following configuration is also vulnerable: logging enable ! logging list MYLIST level informational <and/or> logging list MYLIST message 302015 ! logging trap MYLIST Note: The default severity level of system log messages can be changed. If the default severity level of system log message 302015 is changed, and the device is configured to log to any destination at the new severity level, then the device is still vulnerable. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use Authentication, Authorization, and Accounting (AAA) for network access, also known as cut-through or authentication proxy. The network access authentication feature is enabled if the aaa authentication match or aaa authentication include commands are present in the configuration of an affected device. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use the Terminal Access Controller Access-Control System Plus (TACACS+) protocol for AAA. A device is configured for TACACS+ if an AAA server group is defined in a manner similar to the following: aaa-server my-tacacs-server protocol tacacs+ aaa-server my-tacacs-server (inside) host 192.168.1.1 [...] Note: In the preceding example, "my-tacacs-server" is the name of the AAA server group. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if SunRPC inspection is enabled. SunRPC inspection is enabled by default. To determine whether SunRPC inspection is enabled, issue the show service-policy | include sunrpc command and confirm that the command returns output. Example output follows: FWSM# show service-policy | include sunrpc Inspect: sunrpc, packet 324, drop 5, reset-drop 0 Alternatively, a device with SunRPC inspection enabled has a configuration similar to the following (the inspect sunrpc command is the command that actually enables SunRPC inspection, although the other commands are necessary for the Cisco FWSM to actually inspect traffic): class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ! service-policy global_policy global Note: The service policy could also be applied to a specific interface. (Global application is shown in the previous example.) ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if inspection of the ILS protocol is enabled. ILS inspection is not enabled by default. Refer to "SunRPC Inspection Denial of Service Vulnerabilities" for information on how to determine if ILS inspection is enabled. Use the configuration keyword "ils" instead of "sunrpc". The following example shows a system with a Cisco FWSM (WS-SVC-FWM-1) installed in slot 2: switch>show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 16 SFM-capable 16 port 1000mb GBIC WS-X6516-GBIC SAL06334NS9 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 3 8 Intrusion Detection System WS-SVC-IDSM-2 SAD0932089Z 4 4 SLB Application Processor Complex WS-X6066-SLB-APC SAD093004BD 5 2 Supervisor Engine 720 (Active) WS-SUP720-3B SAL0934888E Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 0009.11e3.ade8 to 0009.11e3.adf7 5.1 6.3(1) 8.7(0.22)BUB Ok 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok 3 0014.a90c.9956 to 0014.a90c.995d 5.0 7.2(1) 7.0(4)E4 Ok 4 0014.a90c.66e6 to 0014.a90c.66ed 1.7 Unknown Unknown PwrDown 5 0013.c42e.7fe0 to 0013.c42e.7fe3 4.4 8.1(3) 12.2(33)SXH8 Ok [...] After locating the correct slot, issue the show module <slot number> command to identify the software version that is running, as shown in the following example: switch>show module 2 Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok [...] The preceding example shows that the Cisco FWSM is running software version 4.0(16) as indicated by the Sw column. Note: Recent versions of Cisco IOS Software will show the software version of each module in the output from the show module command; therefore, executing the show module <slot number> command is not necessary. If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series switches to operate as a single logical virtual switch, the show module switch all command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from show module <slot number> but will include module information for the modules in each switch in the VSS. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- The Cisco FWSM has a system log (syslog) feature that provides information for monitoring normal operation and troubleshooting network or device issues. System log messages are assigned different severities (debugging, informational, error, critical, etc.) and can be sent to different logging destinations. A denial of service vulnerability exists in the implementation of one specific system log message (message ID 302015, "Built outbound UDP connection session-id for src-intf:IP/Port to dst-intf:IP/Port ARP-Incomplete") that can cause memory corruption and lead to a lock up or crash of the Cisco FWSM in the event that that system log message needs to be generated for IPv6 traffic that has flowed through the device. The Cisco FWSM may not recover on its own and a manual reboot may be necessary to recover. System log message 302015 has a default severity level of 6 (informational). Changing the default severity level of this system message will not prevent the issue from occurring if the system is logging to any destinations at the new severity level. The Cisco FWSM must have interfaces with IPv6 addresses otherwise the problem does not occur. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- The Cisco FWSM authentication proxy feature allows one to use AAA to control access to network resources. Specifically, the Cisco FWSM cut-through proxy challenges a user initially at the application layer and then authenticates against AAA servers. After the Cisco FWSM authenticates the user, it shifts the session flow, and all traffic flows directly between the user's computer and the network resource being accessed. A denial of service vulnerability exists in some versions of Cisco FWSM Software that affects devices configured to use authentication to grant users access to the network, also known as cut-through or authentication proxy. Vulnerable configurations are those that contain the aaa authentication match or aaa authentication include commands. The vulnerability may be triggered when there is a high number of network access authentication requests. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the Cisco FWSM to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). The Cisco FWSM supports TACACS+ authentication for VPN users, firewall sessions, and administrative access to the device. An authentication bypass vulnerability exists in the TACACS+ implementation in the Cisco FWSM. Successful exploitation could allow a remote attacker to bypass TACACS+ authentication of VPN users (the Cisco FWSM only allows VPN sessions for management), firewall sessions, or administrative access to the device. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The SunRPC inspection engine enables or disables application inspection for the SunRPC protocol. SunRPC is used by Network File System (NFS) and Network Information Service (NIS). SunRPC services can run on any port. When a client attempts to access a SunRPC service on a server, it must learn the port on which the service is running. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. The Cisco FWSM is affected by four vulnerabilities that may cause the device to reload during the processing of different crafted SunRPC messages when SunRPC inspection is enabled. These vulnerabilities are triggered only by transit traffic; traffic that is destined to the device does not trigger these vulnerabilities. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- The ILS inspection engine provides Network Address Translation (NAT) support for Microsoft NetMeeting, SiteServer, and Active Directory products that use Lightweight Directory Access Protocol (LDAP) to exchange directory information with an ILS server. This vulnerability is triggered by transit traffic only; traffic that is destined to the device does not trigger this vulnerability. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCti83875 -- Syslog message 302015 may lead to memory corruption and CP lockup CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtn15697 -- FWSM crash in thread name uauth CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCto74274 -- Crafted TACACS+ reply considered as successful auth by FWSM CVSS Base Score - 7.9 Access Vector - Adjacent Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * SunRPC Inspection Denial of Service Vulnerabilities CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtq57802 -- ILS inspection crash on malformed ILS traffic CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of any of the denial of service vulnerabilities could cause an affected device to reload. Repeated exploitation could result in a sustained denial of service condition. Successful exploitation of the TACACS+ authentication bypass vulnerability could allow an attacker to bypass authentication of VPN, firewall, and/or administrative sessions. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco FWSM Software table describes a major Cisco FWSM Software train and the earliest possible release in that train that contains the fix (the "First Fixed Release") and the anticipated date of availability (if not currently available) in the First Fixed Release column. A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. A vulnerable release should be upgraded to the indicated release at a minimum, or a later version (later than or equal to the First Fixed Release label). These vulnerabilities and their respective workarounds are independent of each other. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Completely disabling syslog 302015 with the command no logging message 302015 is an effective workaround for this vulnerability. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- There are no workarounds available for this vulnerability. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ There are no workarounds available for this vulnerability other than using a different authentication protocol such as RADIUS and LDAP. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Administrators can mitigate these vulnerabilities by disabling SunRPC inspection if it is not required. Administrators can disable SunRPC inspection by issuing the no inspect sunrpc command in class configuration sub-mode in the policy map configuration. Disabling SunRPC inspection may cause SunRPC traffic to stop transiting the security appliance. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Administrators can mitigate this vulnerability by disabling ILS inspection if it is not required. Administrators can disable ILS inspection by issuing the no inspect ils command in class configuration sub-mode in the policy map configuration. Disabling ILS inspection may cause ILS traffic to stop through the security appliance. Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased.

Note: Recent versions of Cisco IOS Software will show the software version of each module in the output from the show module command; therefore, executing the show module <slot number> command is not necessary. If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series switches to operate as a single logical virtual switch, the show module switch all command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from show module <slot number> but will include module information for the modules in each switch in the VSS. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- The Cisco FWSM has a system log (syslog) feature that provides information for monitoring normal operation and troubleshooting network or device issues. System log messages are assigned different severities (debugging, informational, error, critical, etc.) and can be sent to different logging destinations. A denial of service vulnerability exists in the implementation of one specific system log message (message ID 302015, "Built outbound UDP connection session-id for src-intf:IP/Port to dst-intf:IP/Port ARP-Incomplete") that can cause memory corruption and lead to a lock up or crash of the Cisco FWSM in the event that that system log message needs to be generated for IPv6 traffic that has flowed through the device. The Cisco FWSM may not recover on its own and a manual reboot may be necessary to recover. System log message 302015 has a default severity level of 6 (informational). Changing the default severity level of this system message will not prevent the issue from occurring if the system is logging to any destinations at the new severity level. The Cisco FWSM must have interfaces with IPv6 addresses otherwise the problem does not occur. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- The Cisco FWSM authentication proxy feature allows one to use AAA to control access to network resources. Specifically, the Cisco FWSM cut-through proxy challenges a user initially at the application layer and then authenticates against AAA servers. After the Cisco FWSM authenticates the user, it shifts the session flow, and all traffic flows directly between the user's computer and the network resource being accessed. A denial of service vulnerability exists in some versions of Cisco FWSM Software that affects devices configured to use authentication to grant users access to the network, also known as cut-through or authentication proxy. Vulnerable configurations are those that contain the aaa authentication match or aaa authentication include commands. The vulnerability may be triggered when there is a high number of network access authentication requests. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the Cisco FWSM to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). The Cisco FWSM supports TACACS+ authentication for VPN users, firewall sessions, and administrative access to the device. An authentication bypass vulnerability exists in the TACACS+ implementation in the Cisco FWSM. Successful exploitation could allow a remote attacker to bypass TACACS+ authentication of VPN users (the Cisco FWSM only allows VPN sessions for management), firewall sessions, or administrative access to the device. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The SunRPC inspection engine enables or disables application inspection for the SunRPC protocol. SunRPC is used by Network File System (NFS) and Network Information Service (NIS). SunRPC services can run on any port. When a client attempts to access a SunRPC service on a server, it must learn the port on which the service is running. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. These vulnerabilities are triggered only by transit traffic; traffic that is destined to the device does not trigger these vulnerabilities. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- The ILS inspection engine provides Network Address Translation (NAT) support for Microsoft NetMeeting, SiteServer, and Active Directory products that use Lightweight Directory Access Protocol (LDAP) to exchange directory information with an ILS server. The Cisco FWSM is affected by a vulnerability when ILS inspection is enabled that may cause the device to reload during the processing of a malformed ILS message. This vulnerability is triggered by transit traffic only; traffic that is destined to the device does not trigger this vulnerability. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCti83875 -- Syslog message 302015 may lead to memory corruption and CP lockup CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtn15697 -- FWSM crash in thread name uauth CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCto74274 -- Crafted TACACS+ reply considered as successful auth by FWSM CVSS Base Score - 7.9 Access Vector - Adjacent Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * SunRPC Inspection Denial of Service Vulnerabilities CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtq57802 -- ILS inspection crash on malformed ILS traffic CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of any of the denial of service vulnerabilities could cause an affected device to reload. Repeated exploitation could result in a sustained denial of service condition. Successful exploitation of the TACACS+ authentication bypass vulnerability could allow an attacker to bypass authentication of VPN, firewall, and/or administrative sessions. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco FWSM Software table describes a major Cisco FWSM Software train and the earliest possible release in that train that contains the fix (the "First Fixed Release") and the anticipated date of availability (if not currently available) in the First Fixed Release column. A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. A vulnerable release should be upgraded to the indicated release at a minimum, or a later version (later than or equal to the First Fixed Release label). These vulnerabilities and their respective workarounds are independent of each other. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Completely disabling syslog 302015 with the command no logging message 302015 is an effective workaround for this vulnerability. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- There are no workarounds available for this vulnerability. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ There are no workarounds available for this vulnerability other than using a different authentication protocol such as RADIUS and LDAP. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Administrators can mitigate these vulnerabilities by disabling SunRPC inspection if it is not required. Administrators can disable SunRPC inspection by issuing the no inspect sunrpc command in class configuration sub-mode in the policy map configuration. Disabling SunRPC inspection may cause SunRPC traffic to stop transiting the security appliance. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Administrators can mitigate this vulnerability by disabling ILS inspection if it is not required. Administrators can disable ILS inspection by issuing the no inspect ils command in class configuration sub-mode in the policy map configuration. Disabling ILS inspection may cause ILS traffic to stop through the security appliance. Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased.

Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of the vulnerabilities disclosed in this advisory. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. Refer to the "Software Version and Fixes" section for specific information on vulnerable versions. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if the following conditions are satisfied: * The device has interfaces with IPv6 addresses * System logging is enabled (command logging enable) * The device is configured in any way to generate system log message 302015 (refer to the following examples) System log message 302015 has a default severity level of 6 (informational) so, assuming that the system administrator has not changed this default severity level, the vulnerability can be triggered if the device is logging to any destination at level 6 or level 7 (debug). As an example, the following configuration is vulnerable: logging enable ! logging console informational logging buffered informational [...] Using a custom message list (via the logging list command) that includes system log message 302015, either by severity or by explicitly including the message ID, is also a vulnerable configuration. For example, the following configuration is also vulnerable: logging enable ! logging list MYLIST level informational <and/or> logging list MYLIST message 302015 ! logging trap MYLIST Note: The default severity level of system log messages can be changed. If the default severity level of system log message 302015 is changed, and the device is configured to log to any destination at the new severity level, then the device is still vulnerable. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use Authentication, Authorization, and Accounting (AAA) for network access, also known as cut-through or authentication proxy. The network access authentication feature is enabled if the aaa authentication match or aaa authentication include commands are present in the configuration of an affected device. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use the Terminal Access Controller Access-Control System Plus (TACACS+) protocol for AAA. A device is configured for TACACS+ if an AAA server group is defined in a manner similar to the following: aaa-server my-tacacs-server protocol tacacs+ aaa-server my-tacacs-server (inside) host 192.168.1.1 [...] Note: In the preceding example, "my-tacacs-server" is the name of the AAA server group. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if SunRPC inspection is enabled. SunRPC inspection is enabled by default. To determine whether SunRPC inspection is enabled, issue the show service-policy | include sunrpc command and confirm that the command returns output. Example output follows: FWSM# show service-policy | include sunrpc Inspect: sunrpc, packet 324, drop 5, reset-drop 0 Alternatively, a device with SunRPC inspection enabled has a configuration similar to the following (the inspect sunrpc command is the command that actually enables SunRPC inspection, although the other commands are necessary for the Cisco FWSM to actually inspect traffic): class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ! service-policy global_policy global Note: The service policy could also be applied to a specific interface. (Global application is shown in the previous example.) ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if inspection of the ILS protocol is enabled. ILS inspection is not enabled by default. Refer to "SunRPC Inspection Denial of Service Vulnerabilities" for information on how to determine if ILS inspection is enabled. Use the configuration keyword "ils" instead of "sunrpc".

Note: Recent versions of Cisco IOS Software will show the software version of each module in the output from the show module command; therefore, executing the show module <slot number> command is not necessary. If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series switches to operate as a single logical virtual switch, the show module switch all command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from show module <slot number> but will include module information for the modules in each switch in the VSS. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- The Cisco FWSM has a system log (syslog) feature that provides information for monitoring normal operation and troubleshooting network or device issues. System log messages are assigned different severities (debugging, informational, error, critical, etc.) and can be sent to different logging destinations. A denial of service vulnerability exists in the implementation of one specific system log message (message ID 302015, "Built outbound UDP connection session-id for src-intf:IP/Port to dst-intf:IP/Port ARP-Incomplete") that can cause memory corruption and lead to a lock up or crash of the Cisco FWSM in the event that that system log message needs to be generated for IPv6 traffic that has flowed through the device. The Cisco FWSM may not recover on its own and a manual reboot may be necessary to recover. System log message 302015 has a default severity level of 6 (informational). Changing the default severity level of this system message will not prevent the issue from occurring if the system is logging to any destinations at the new severity level. The Cisco FWSM must have interfaces with IPv6 addresses otherwise the problem does not occur. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- The Cisco FWSM authentication proxy feature allows one to use AAA to control access to network resources. Specifically, the Cisco FWSM cut-through proxy challenges a user initially at the application layer and then authenticates against AAA servers. After the Cisco FWSM authenticates the user, it shifts the session flow, and all traffic flows directly between the user's computer and the network resource being accessed. A denial of service vulnerability exists in some versions of Cisco FWSM Software that affects devices configured to use authentication to grant users access to the network, also known as cut-through or authentication proxy. Vulnerable configurations are those that contain the aaa authentication match or aaa authentication include commands. The vulnerability may be triggered when there is a high number of network access authentication requests. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the Cisco FWSM to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). The Cisco FWSM supports TACACS+ authentication for VPN users, firewall sessions, and administrative access to the device. An authentication bypass vulnerability exists in the TACACS+ implementation in the Cisco FWSM. Successful exploitation could allow a remote attacker to bypass TACACS+ authentication of VPN users (the Cisco FWSM only allows VPN sessions for management), firewall sessions, or administrative access to the device. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The SunRPC inspection engine enables or disables application inspection for the SunRPC protocol. SunRPC is used by Network File System (NFS) and Network Information Service (NIS). SunRPC services can run on any port. When a client attempts to access a SunRPC service on a server, it must learn the port on which the service is running. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. These vulnerabilities are triggered only by transit traffic; traffic that is destined to the device does not trigger these vulnerabilities.

Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco FWSM Software table describes a major Cisco FWSM Software train and the earliest possible release in that train that contains the fix (the "First Fixed Release") and the anticipated date of availability (if not currently available) in the First Fixed Release column. A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. A vulnerable release should be upgraded to the indicated release at a minimum, or a later version (later than or equal to the First Fixed Release label). These vulnerabilities and their respective workarounds are independent of each other. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Completely disabling syslog 302015 with the command no logging message 302015 is an effective workaround for this vulnerability. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- There are no workarounds available for this vulnerability. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ There are no workarounds available for this vulnerability other than using a different authentication protocol such as RADIUS and LDAP. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Administrators can mitigate these vulnerabilities by disabling SunRPC inspection if it is not required. Administrators can disable SunRPC inspection by issuing the no inspect sunrpc command in class configuration sub-mode in the policy map configuration.

Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of the vulnerabilities disclosed in this advisory. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. Refer to the "Software Version and Fixes" section for specific information on vulnerable versions. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if the following conditions are satisfied: * The device has interfaces with IPv6 addresses * System logging is enabled (command logging enable) * The device is configured in any way to generate system log message 302015 (refer to the following examples) System log message 302015 has a default severity level of 6 (informational) so, assuming that the system administrator has not changed this default severity level, the vulnerability can be triggered if the device is logging to any destination at level 6 or level 7 (debug). As an example, the following configuration is vulnerable: logging enable ! logging console informational logging buffered informational [...] Using a custom message list (via the logging list command) that includes system log message 302015, either by severity or by explicitly including the message ID, is also a vulnerable configuration. For example, the following configuration is also vulnerable: logging enable ! logging list MYLIST level informational <and/or> logging list MYLIST message 302015 ! logging trap MYLIST Note: The default severity level of system log messages can be changed. If the default severity level of system log message 302015 is changed, and the device is configured to log to any destination at the new severity level, then the device is still vulnerable. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use Authentication, Authorization, and Accounting (AAA) for network access, also known as cut-through or authentication proxy. The network access authentication feature is enabled if the aaa authentication match or aaa authentication include commands are present in the configuration of an affected device. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use the Terminal Access Controller Access-Control System Plus (TACACS+) protocol for AAA. A device is configured for TACACS+ if an AAA server group is defined in a manner similar to the following: aaa-server my-tacacs-server protocol tacacs+ aaa-server my-tacacs-server (inside) host 192.168.1.1 [...] Note: In the preceding example, "my-tacacs-server" is the name of the AAA server group. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if SunRPC inspection is enabled. SunRPC inspection is enabled by default. To determine whether SunRPC inspection is enabled, issue the show service-policy | include sunrpc command and confirm that the command returns output. Example output follows: FWSM# show service-policy | include sunrpc Inspect: sunrpc, packet 324, drop 5, reset-drop 0 Alternatively, a device with SunRPC inspection enabled has a configuration similar to the following (the inspect sunrpc command is the command that actually enables SunRPC inspection, although the other commands are necessary for the Cisco FWSM to actually inspect traffic): class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ! service-policy global_policy global Note: The service policy could also be applied to a specific interface. (Global application is shown in the previous example.) ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if inspection of the ILS protocol is enabled. ILS inspection is not enabled by default. Refer to "SunRPC Inspection Denial of Service Vulnerabilities" for information on how to determine if ILS inspection is enabled. Use the configuration keyword "ils" instead of "sunrpc". The following example shows a system with a Cisco FWSM (WS-SVC-FWM-1) installed in slot 2: switch>show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 16 SFM-capable 16 port 1000mb GBIC WS-X6516-GBIC SAL06334NS9 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 3 8 Intrusion Detection System WS-SVC-IDSM-2 SAD0932089Z 4 4 SLB Application Processor Complex WS-X6066-SLB-APC SAD093004BD 5 2 Supervisor Engine 720 (Active) WS-SUP720-3B SAL0934888E Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 0009.11e3.ade8 to 0009.11e3.adf7 5.1 6.3(1) 8.7(0.22)BUB Ok 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok 3 0014.a90c.9956 to 0014.a90c.995d 5.0 7.2(1) 7.0(4)E4 Ok 4 0014.a90c.66e6 to 0014.a90c.66ed 1.7 Unknown Unknown PwrDown 5 0013.c42e.7fe0 to 0013.c42e.7fe3 4.4 8.1(3) 12.2(33)SXH8 Ok [...] After locating the correct slot, issue the show module <slot number> command to identify the software version that is running, as shown in the following example: switch>show module 2 Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok [...] The preceding example shows that the Cisco FWSM is running software version 4.0(16) as indicated by the Sw column. Note: Recent versions of Cisco IOS Software will show the software version of each module in the output from the show module command; therefore, executing the show module <slot number> command is not necessary. If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series switches to operate as a single logical virtual switch, the show module switch all command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from show module <slot number> but will include module information for the modules in each switch in the VSS. Alternatively, version information can be obtained directly from the Cisco FWSM through the show version command, as shown in the following example: FWSM> show version FWSM Firewall Version 4.0(16) [...] Customers who use the Cisco Adaptive Security Device Manager (ASDM) to manage their devices can find the version of the software displayed in the table in the login window or in the upper left corner of the Cisco ASDM window. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. The Cisco FWSM is affected by multiple vulnerabilities, which are described in the following sections. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- The Cisco FWSM has a system log (syslog) feature that provides information for monitoring normal operation and troubleshooting network or device issues. System log messages are assigned different severities (debugging, informational, error, critical, etc.) and can be sent to different logging destinations. A denial of service vulnerability exists in the implementation of one specific system log message (message ID 302015, "Built outbound UDP connection session-id for src-intf:IP/Port to dst-intf:IP/Port ARP-Incomplete") that can cause memory corruption and lead to a lock up or crash of the Cisco FWSM in the event that that system log message needs to be generated for IPv6 traffic that has flowed through the device. The Cisco FWSM may not recover on its own and a manual reboot may be necessary to recover. System log message 302015 has a default severity level of 6 (informational). Changing the default severity level of this system message will not prevent the issue from occurring if the system is logging to any destinations at the new severity level. The Cisco FWSM must have interfaces with IPv6 addresses otherwise the problem does not occur. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- The Cisco FWSM authentication proxy feature allows one to use AAA to control access to network resources. Specifically, the Cisco FWSM cut-through proxy challenges a user initially at the application layer and then authenticates against AAA servers. After the Cisco FWSM authenticates the user, it shifts the session flow, and all traffic flows directly between the user's computer and the network resource being accessed. A denial of service vulnerability exists in some versions of Cisco FWSM Software that affects devices configured to use authentication to grant users access to the network, also known as cut-through or authentication proxy. Vulnerable configurations are those that contain the aaa authentication match or aaa authentication include commands. The vulnerability may be triggered when there is a high number of network access authentication requests. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the Cisco FWSM to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). The Cisco FWSM supports TACACS+ authentication for VPN users, firewall sessions, and administrative access to the device. An authentication bypass vulnerability exists in the TACACS+ implementation in the Cisco FWSM. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The SunRPC inspection engine enables or disables application inspection for the SunRPC protocol. SunRPC is used by Network File System (NFS) and Network Information Service (NIS). SunRPC services can run on any port. When a client attempts to access a SunRPC service on a server, it must learn the port on which the service is running. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. The Cisco FWSM is affected by four vulnerabilities that may cause the device to reload during the processing of different crafted SunRPC messages when SunRPC inspection is enabled. These vulnerabilities are triggered only by transit traffic; traffic that is destined to the device does not trigger these vulnerabilities. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- The ILS inspection engine provides Network Address Translation (NAT) support for Microsoft NetMeeting, SiteServer, and Active Directory products that use Lightweight Directory Access Protocol (LDAP) to exchange directory information with an ILS server. The Cisco FWSM is affected by a vulnerability when ILS inspection is enabled that may cause the device to reload during the processing of a malformed ILS message. This vulnerability is triggered by transit traffic only; traffic that is destined to the device does not trigger this vulnerability. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCti83875 -- Syslog message 302015 may lead to memory corruption and CP lockup CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtn15697 -- FWSM crash in thread name uauth CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCto74274 -- Crafted TACACS+ reply considered as successful auth by FWSM CVSS Base Score - 7.9 Access Vector - Adjacent Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * SunRPC Inspection Denial of Service Vulnerabilities CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtq57802 -- ILS inspection crash on malformed ILS traffic CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of any of the denial of service vulnerabilities could cause an affected device to reload. Repeated exploitation could result in a sustained denial of service condition. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release.

A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. A vulnerable release should be upgraded to the indicated release at a minimum, or a later version (later than or equal to the First Fixed Release label). Workarounds =========== This Cisco Security Advisory describes multiple distinct vulnerabilities. These vulnerabilities and their respective workarounds are independent of each other.

Cisco Firewall Services Module (aka FWSM) 3.1 before 3.1(21), 3.2 before 3.2(22), 4.0 before 4.0(16), and 4.1 before 4.1(7), when certain authentication configurations are used, allows remote attackers to cause a denial of service (module crash) by making many authentication requests for network access, aka Bug ID CSCtn15697. ( Module crash ) There is a vulnerability that becomes a condition. ( Module crash ) There is a possibility of being put into a state. An attacker can exploit this issue to cause the affected devices to reload, triggering a denial-of-service condition. This issue is tracked by Cisco Bug ID CSCtn15697. Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of the vulnerabilities disclosed in this advisory. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. Refer to the "Software Version and Fixes" section for specific information on vulnerable versions. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if the following conditions are satisfied: * The device has interfaces with IPv6 addresses * System logging is enabled (command logging enable) * The device is configured in any way to generate system log message 302015 (refer to the following examples) System log message 302015 has a default severity level of 6 (informational) so, assuming that the system administrator has not changed this default severity level, the vulnerability can be triggered if the device is logging to any destination at level 6 or level 7 (debug). As an example, the following configuration is vulnerable: logging enable ! logging console informational logging buffered informational [...] Using a custom message list (via the logging list command) that includes system log message 302015, either by severity or by explicitly including the message ID, is also a vulnerable configuration. For example, the following configuration is also vulnerable: logging enable ! logging list MYLIST level informational <and/or> logging list MYLIST message 302015 ! logging trap MYLIST Note: The default severity level of system log messages can be changed. If the default severity level of system log message 302015 is changed, and the device is configured to log to any destination at the new severity level, then the device is still vulnerable. The network access authentication feature is enabled if the aaa authentication match or aaa authentication include commands are present in the configuration of an affected device. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use the Terminal Access Controller Access-Control System Plus (TACACS+) protocol for AAA. A device is configured for TACACS+ if an AAA server group is defined in a manner similar to the following: aaa-server my-tacacs-server protocol tacacs+ aaa-server my-tacacs-server (inside) host 192.168.1.1 [...] Note: In the preceding example, "my-tacacs-server" is the name of the AAA server group. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if SunRPC inspection is enabled. SunRPC inspection is enabled by default. To determine whether SunRPC inspection is enabled, issue the show service-policy | include sunrpc command and confirm that the command returns output. Example output follows: FWSM# show service-policy | include sunrpc Inspect: sunrpc, packet 324, drop 5, reset-drop 0 Alternatively, a device with SunRPC inspection enabled has a configuration similar to the following (the inspect sunrpc command is the command that actually enables SunRPC inspection, although the other commands are necessary for the Cisco FWSM to actually inspect traffic): class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ! service-policy global_policy global Note: The service policy could also be applied to a specific interface. (Global application is shown in the previous example.) ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if inspection of the ILS protocol is enabled. ILS inspection is not enabled by default. Refer to "SunRPC Inspection Denial of Service Vulnerabilities" for information on how to determine if ILS inspection is enabled. Use the configuration keyword "ils" instead of "sunrpc". How to Determine the Running Software Version +-------------------------------------------- To determine the version of Cisco FWSM Software that is running on a device, issue the show module command from Cisco IOS Software or Cisco Catalyst Operating System Software to identify what modules and submodules are installed on the system. The following example shows a system with a Cisco FWSM (WS-SVC-FWM-1) installed in slot 2: switch>show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 16 SFM-capable 16 port 1000mb GBIC WS-X6516-GBIC SAL06334NS9 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 3 8 Intrusion Detection System WS-SVC-IDSM-2 SAD0932089Z 4 4 SLB Application Processor Complex WS-X6066-SLB-APC SAD093004BD 5 2 Supervisor Engine 720 (Active) WS-SUP720-3B SAL0934888E Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 0009.11e3.ade8 to 0009.11e3.adf7 5.1 6.3(1) 8.7(0.22)BUB Ok 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok 3 0014.a90c.9956 to 0014.a90c.995d 5.0 7.2(1) 7.0(4)E4 Ok 4 0014.a90c.66e6 to 0014.a90c.66ed 1.7 Unknown Unknown PwrDown 5 0013.c42e.7fe0 to 0013.c42e.7fe3 4.4 8.1(3) 12.2(33)SXH8 Ok [...] After locating the correct slot, issue the show module <slot number> command to identify the software version that is running, as shown in the following example: switch>show module 2 Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok [...] The preceding example shows that the Cisco FWSM is running software version 4.0(16) as indicated by the Sw column. Note: Recent versions of Cisco IOS Software will show the software version of each module in the output from the show module command; therefore, executing the show module <slot number> command is not necessary. If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series switches to operate as a single logical virtual switch, the show module switch all command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from show module <slot number> but will include module information for the modules in each switch in the VSS. Alternatively, version information can be obtained directly from the Cisco FWSM through the show version command, as shown in the following example: FWSM> show version FWSM Firewall Version 4.0(16) [...] Customers who use the Cisco Adaptive Security Device Manager (ASDM) to manage their devices can find the version of the software displayed in the table in the login window or in the upper left corner of the Cisco ASDM window. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. The Cisco FWSM is affected by multiple vulnerabilities, which are described in the following sections. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- The Cisco FWSM has a system log (syslog) feature that provides information for monitoring normal operation and troubleshooting network or device issues. System log messages are assigned different severities (debugging, informational, error, critical, etc.) and can be sent to different logging destinations. A denial of service vulnerability exists in the implementation of one specific system log message (message ID 302015, "Built outbound UDP connection session-id for src-intf:IP/Port to dst-intf:IP/Port ARP-Incomplete") that can cause memory corruption and lead to a lock up or crash of the Cisco FWSM in the event that that system log message needs to be generated for IPv6 traffic that has flowed through the device. The Cisco FWSM may not recover on its own and a manual reboot may be necessary to recover. System log message 302015 has a default severity level of 6 (informational). Changing the default severity level of this system message will not prevent the issue from occurring if the system is logging to any destinations at the new severity level. The Cisco FWSM must have interfaces with IPv6 addresses otherwise the problem does not occur. Specifically, the Cisco FWSM cut-through proxy challenges a user initially at the application layer and then authenticates against AAA servers. After the Cisco FWSM authenticates the user, it shifts the session flow, and all traffic flows directly between the user's computer and the network resource being accessed. Vulnerable configurations are those that contain the aaa authentication match or aaa authentication include commands. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the Cisco FWSM to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). An authentication bypass vulnerability exists in the TACACS+ implementation in the Cisco FWSM. Successful exploitation could allow a remote attacker to bypass TACACS+ authentication of VPN users (the Cisco FWSM only allows VPN sessions for management), firewall sessions, or administrative access to the device. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The SunRPC inspection engine enables or disables application inspection for the SunRPC protocol. SunRPC is used by Network File System (NFS) and Network Information Service (NIS). SunRPC services can run on any port. When a client attempts to access a SunRPC service on a server, it must learn the port on which the service is running. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. The Cisco FWSM is affected by four vulnerabilities that may cause the device to reload during the processing of different crafted SunRPC messages when SunRPC inspection is enabled. These vulnerabilities are triggered only by transit traffic; traffic that is destined to the device does not trigger these vulnerabilities. These vulnerabilities are documented in Cisco bug IDs CSCtq09972 CSCtq09978, CSCtq09986, and CSCtq09989; and have been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2011-3299, CVE-2011-3300, CVE-2011-3301, and CVE-2011-3302, respectively. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- The ILS inspection engine provides Network Address Translation (NAT) support for Microsoft NetMeeting, SiteServer, and Active Directory products that use Lightweight Directory Access Protocol (LDAP) to exchange directory information with an ILS server. The Cisco FWSM is affected by a vulnerability when ILS inspection is enabled that may cause the device to reload during the processing of a malformed ILS message. This vulnerability is triggered by transit traffic only; traffic that is destined to the device does not trigger this vulnerability. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCti83875 -- Syslog message 302015 may lead to memory corruption and CP lockup CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtn15697 -- FWSM crash in thread name uauth CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCto74274 -- Crafted TACACS+ reply considered as successful auth by FWSM CVSS Base Score - 7.9 Access Vector - Adjacent Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * SunRPC Inspection Denial of Service Vulnerabilities CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtq57802 -- ILS inspection crash on malformed ILS traffic CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of any of the denial of service vulnerabilities could cause an affected device to reload. Repeated exploitation could result in a sustained denial of service condition. Successful exploitation of the TACACS+ authentication bypass vulnerability could allow an attacker to bypass authentication of VPN, firewall, and/or administrative sessions. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco FWSM Software table describes a major Cisco FWSM Software train and the earliest possible release in that train that contains the fix (the "First Fixed Release") and the anticipated date of availability (if not currently available) in the First Fixed Release column. A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. A vulnerable release should be upgraded to the indicated release at a minimum, or a later version (later than or equal to the First Fixed Release label). Workarounds =========== This Cisco Security Advisory describes multiple distinct vulnerabilities. These vulnerabilities and their respective workarounds are independent of each other. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Completely disabling syslog 302015 with the command no logging message 302015 is an effective workaround for this vulnerability. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- There are no workarounds available for this vulnerability. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ There are no workarounds available for this vulnerability other than using a different authentication protocol such as RADIUS and LDAP. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Administrators can mitigate these vulnerabilities by disabling SunRPC inspection if it is not required. Administrators can disable SunRPC inspection by issuing the no inspect sunrpc command in class configuration sub-mode in the policy map configuration. Disabling SunRPC inspection may cause SunRPC traffic to stop transiting the security appliance. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Administrators can mitigate this vulnerability by disabling ILS inspection if it is not required. Administrators can disable ILS inspection by issuing the no inspect ils command in class configuration sub-mode in the policy map configuration. Disabling ILS inspection may cause ILS traffic to stop through the security appliance. Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased.

Cisco Firewall Services Module (aka FWSM) 3.1 before 3.1(21), 3.2 before 3.2(22), 4.0 before 4.0(16), and 4.1 before 4.1(7), when IPv6 is used, allows remote attackers to cause a denial of service (memory corruption and module crash or hang) via vectors that trigger syslog message 302015, aka Bug ID CSCti83875. An attacker can exploit this issue to cause the affected application to crash, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCti83875. Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of the vulnerabilities disclosed in this advisory. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20111005-fwsm.shtml Note: Cisco ASA 5500 Series Adaptive Security Appliances and the Cisco Catalyst 6500 Series ASA Services Module are affected by some of the vulnerabilities described in this advisory. A separate Cisco Security Advisory has been published to disclose these and other vulnerabilities that affect the Cisco ASA 5500 Series Adaptive Security Appliances and the Cisco Catalyst 6500 Series ASA Services Module. The advisory is available at: http://www.cisco.com/warp/public/707/cisco-sa-20111005-asa.shtml Affected Products ================= Vulnerable Products +------------------ The Cisco FWSM for the Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers is affected by multiple vulnerabilities. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. Refer to the "Software Version and Fixes" section for specific information on vulnerable versions. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if the following conditions are satisfied: * The device has interfaces with IPv6 addresses * System logging is enabled (command logging enable) * The device is configured in any way to generate system log message 302015 (refer to the following examples) System log message 302015 has a default severity level of 6 (informational) so, assuming that the system administrator has not changed this default severity level, the vulnerability can be triggered if the device is logging to any destination at level 6 or level 7 (debug). As an example, the following configuration is vulnerable: logging enable ! logging console informational logging buffered informational [...] Using a custom message list (via the logging list command) that includes system log message 302015, either by severity or by explicitly including the message ID, is also a vulnerable configuration. For example, the following configuration is also vulnerable: logging enable ! logging list MYLIST level informational <and/or> logging list MYLIST message 302015 ! logging trap MYLIST Note: The default severity level of system log messages can be changed. If the default severity level of system log message 302015 is changed, and the device is configured to log to any destination at the new severity level, then the device is still vulnerable. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use Authentication, Authorization, and Accounting (AAA) for network access, also known as cut-through or authentication proxy. The network access authentication feature is enabled if the aaa authentication match or aaa authentication include commands are present in the configuration of an affected device. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use the Terminal Access Controller Access-Control System Plus (TACACS+) protocol for AAA. A device is configured for TACACS+ if an AAA server group is defined in a manner similar to the following: aaa-server my-tacacs-server protocol tacacs+ aaa-server my-tacacs-server (inside) host 192.168.1.1 [...] Note: In the preceding example, "my-tacacs-server" is the name of the AAA server group. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if SunRPC inspection is enabled. SunRPC inspection is enabled by default. To determine whether SunRPC inspection is enabled, issue the show service-policy | include sunrpc command and confirm that the command returns output. Example output follows: FWSM# show service-policy | include sunrpc Inspect: sunrpc, packet 324, drop 5, reset-drop 0 Alternatively, a device with SunRPC inspection enabled has a configuration similar to the following (the inspect sunrpc command is the command that actually enables SunRPC inspection, although the other commands are necessary for the Cisco FWSM to actually inspect traffic): class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ! service-policy global_policy global Note: The service policy could also be applied to a specific interface. (Global application is shown in the previous example.) ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if inspection of the ILS protocol is enabled. ILS inspection is not enabled by default. Refer to "SunRPC Inspection Denial of Service Vulnerabilities" for information on how to determine if ILS inspection is enabled. Use the configuration keyword "ils" instead of "sunrpc". How to Determine the Running Software Version +-------------------------------------------- To determine the version of Cisco FWSM Software that is running on a device, issue the show module command from Cisco IOS Software or Cisco Catalyst Operating System Software to identify what modules and submodules are installed on the system. The following example shows a system with a Cisco FWSM (WS-SVC-FWM-1) installed in slot 2: switch>show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 16 SFM-capable 16 port 1000mb GBIC WS-X6516-GBIC SAL06334NS9 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 3 8 Intrusion Detection System WS-SVC-IDSM-2 SAD0932089Z 4 4 SLB Application Processor Complex WS-X6066-SLB-APC SAD093004BD 5 2 Supervisor Engine 720 (Active) WS-SUP720-3B SAL0934888E Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 0009.11e3.ade8 to 0009.11e3.adf7 5.1 6.3(1) 8.7(0.22)BUB Ok 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok 3 0014.a90c.9956 to 0014.a90c.995d 5.0 7.2(1) 7.0(4)E4 Ok 4 0014.a90c.66e6 to 0014.a90c.66ed 1.7 Unknown Unknown PwrDown 5 0013.c42e.7fe0 to 0013.c42e.7fe3 4.4 8.1(3) 12.2(33)SXH8 Ok [...] After locating the correct slot, issue the show module <slot number> command to identify the software version that is running, as shown in the following example: switch>show module 2 Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok [...] The preceding example shows that the Cisco FWSM is running software version 4.0(16) as indicated by the Sw column. Note: Recent versions of Cisco IOS Software will show the software version of each module in the output from the show module command; therefore, executing the show module <slot number> command is not necessary. If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series switches to operate as a single logical virtual switch, the show module switch all command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from show module <slot number> but will include module information for the modules in each switch in the VSS. Alternatively, version information can be obtained directly from the Cisco FWSM through the show version command, as shown in the following example: FWSM> show version FWSM Firewall Version 4.0(16) [...] Customers who use the Cisco Adaptive Security Device Manager (ASDM) to manage their devices can find the version of the software displayed in the table in the login window or in the upper left corner of the Cisco ASDM window. The version notation is similar to the following example: FWSM Version: 4.0(16) Products Confirmed Not Vulnerable +-------------------------------- With the exception of Cisco ASA 5500 Series Adaptive Security Appliances and the Cisco Catalyst 6500 Series ASA Services Module, no other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco FWSM is a high-speed, integrated firewall module for Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. The Cisco FWSM is affected by multiple vulnerabilities, which are described in the following sections. System log messages are assigned different severities (debugging, informational, error, critical, etc.) and can be sent to different logging destinations. The Cisco FWSM may not recover on its own and a manual reboot may be necessary to recover. System log message 302015 has a default severity level of 6 (informational). Changing the default severity level of this system message will not prevent the issue from occurring if the system is logging to any destinations at the new severity level. The Cisco FWSM must have interfaces with IPv6 addresses otherwise the problem does not occur. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- The Cisco FWSM authentication proxy feature allows one to use AAA to control access to network resources. Specifically, the Cisco FWSM cut-through proxy challenges a user initially at the application layer and then authenticates against AAA servers. After the Cisco FWSM authenticates the user, it shifts the session flow, and all traffic flows directly between the user's computer and the network resource being accessed. A denial of service vulnerability exists in some versions of Cisco FWSM Software that affects devices configured to use authentication to grant users access to the network, also known as cut-through or authentication proxy. Vulnerable configurations are those that contain the aaa authentication match or aaa authentication include commands. The vulnerability may be triggered when there is a high number of network access authentication requests. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the Cisco FWSM to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). The Cisco FWSM supports TACACS+ authentication for VPN users, firewall sessions, and administrative access to the device. An authentication bypass vulnerability exists in the TACACS+ implementation in the Cisco FWSM. Successful exploitation could allow a remote attacker to bypass TACACS+ authentication of VPN users (the Cisco FWSM only allows VPN sessions for management), firewall sessions, or administrative access to the device. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The SunRPC inspection engine enables or disables application inspection for the SunRPC protocol. SunRPC is used by Network File System (NFS) and Network Information Service (NIS). SunRPC services can run on any port. When a client attempts to access a SunRPC service on a server, it must learn the port on which the service is running. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. The Cisco FWSM is affected by four vulnerabilities that may cause the device to reload during the processing of different crafted SunRPC messages when SunRPC inspection is enabled. These vulnerabilities are triggered only by transit traffic; traffic that is destined to the device does not trigger these vulnerabilities. These vulnerabilities are documented in Cisco bug IDs CSCtq09972 CSCtq09978, CSCtq09986, and CSCtq09989; and have been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2011-3299, CVE-2011-3300, CVE-2011-3301, and CVE-2011-3302, respectively. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- The ILS inspection engine provides Network Address Translation (NAT) support for Microsoft NetMeeting, SiteServer, and Active Directory products that use Lightweight Directory Access Protocol (LDAP) to exchange directory information with an ILS server. The Cisco FWSM is affected by a vulnerability when ILS inspection is enabled that may cause the device to reload during the processing of a malformed ILS message. This vulnerability is triggered by transit traffic only; traffic that is destined to the device does not trigger this vulnerability. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCti83875 -- Syslog message 302015 may lead to memory corruption and CP lockup CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtn15697 -- FWSM crash in thread name uauth CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCto74274 -- Crafted TACACS+ reply considered as successful auth by FWSM CVSS Base Score - 7.9 Access Vector - Adjacent Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * SunRPC Inspection Denial of Service Vulnerabilities CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtq57802 -- ILS inspection crash on malformed ILS traffic CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of any of the denial of service vulnerabilities could cause an affected device to reload. Repeated exploitation could result in a sustained denial of service condition. Successful exploitation of the TACACS+ authentication bypass vulnerability could allow an attacker to bypass authentication of VPN, firewall, and/or administrative sessions. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco FWSM Software table describes a major Cisco FWSM Software train and the earliest possible release in that train that contains the fix (the "First Fixed Release") and the anticipated date of availability (if not currently available) in the First Fixed Release column. A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. A vulnerable release should be upgraded to the indicated release at a minimum, or a later version (later than or equal to the First Fixed Release label). Workarounds =========== This Cisco Security Advisory describes multiple distinct vulnerabilities. These vulnerabilities and their respective workarounds are independent of each other. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Completely disabling syslog 302015 with the command no logging message 302015 is an effective workaround for this vulnerability. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- There are no workarounds available for this vulnerability. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ There are no workarounds available for this vulnerability other than using a different authentication protocol such as RADIUS and LDAP. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Administrators can mitigate these vulnerabilities by disabling SunRPC inspection if it is not required. Administrators can disable SunRPC inspection by issuing the no inspect sunrpc command in class configuration sub-mode in the policy map configuration. Disabling SunRPC inspection may cause SunRPC traffic to stop transiting the security appliance. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Administrators can mitigate this vulnerability by disabling ILS inspection if it is not required. Administrators can disable ILS inspection by issuing the no inspect ils command in class configuration sub-mode in the policy map configuration. Disabling ILS inspection may cause ILS traffic to stop through the security appliance. Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased.

Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services module in Cisco Catalyst 6500 series devices, with software 7.2 before 7.2(5.3), 8.0 before 8.0(5.25), 8.1 before 8.1(2.50), 8.2 before 8.2(5.11), 8.3 before 8.3(2.23), 8.4 before 8.4(2), and 8.5 before 8.5(1.1) allow remote attackers to cause a denial of service (device reload) via crafted MSN Instant Messenger traffic, aka Bug ID CSCtl67486. The problem is Bug ID CSCtl67486 It is a problem.Skillfully crafted by a third party MSN Instant Messenger Service disruption through traffic (DoS) There is a possibility of being put into a state. An attacker can exploit this issue to cause a vulnerable device to reload, triggering a denial-of-service condition. This issue is tracked by Cisco Bug ID CSCtl67486. Workarounds for some of the vulnerabilities are provided in this advisory. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20111005-asa.shtml. A separate Cisco Security Advisory has been published to disclose the vulnerabilities that affect the FWSM. Affected versions of Cisco ASA Software will vary depending on the specific vulnerability. Vulnerable Products +------------------ For specific version information, refer to the Software Versions and Fixes section of this advisory. MSN IM inspection is not enabled by default. Administrators can enable MSN IM inspection and specify actions when a message violates a parameter, create an IM inspection policy map. In order to enable TACACS+ for authentication, authorization, or accounting (AAA), you must first create at least one AAA server group per AAA protocol and add one or more servers to each group with the "aaa-server" command. You identify AAA server groups by name. SunRPC inspection is enabled by default. To check if SunRPC inspection is enabled, issue the "show service-policy | include sunrpc" command and confirm that output, such as what is displayed in the following example, is returned. ciscoasa# show service-policy | include sunrpc Inspect: sunrpc, packet 0, drop 0, reset-drop 0 The following configuration commands are used to enable SunRPC inspection in the Cisco ASA. class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ... ILS inspection is not enabled by default. To check if ILS inspection is enabled, issue the "show service-policy | include ils" command and confirm that output, such as what is displayed in the following example, is returned. ciscoasa# show service-policy | include ils Inspect: ils, packet 0, drop 0, reset-drop 0 The following configuration commands are used to enable ILS inspection in the Cisco ASA. class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect ils ... ! service-policy global_policy global How to Determine the Running Software Version +-------------------------------------------- To determine whether a vulnerable version of Cisco ASA Software is running on an appliance, administrators can issue the "show version" command. The following example shows a Cisco ASA 5500 Series Adaptive Security Appliance that is running software version 8.4(1): ASA#show version | include Version Cisco Adaptive Security Appliance Software Version 8.4(1) Device Manager Version 6.4(1) Customers who use Cisco ASDM to manage devices can locate the software version in the table that is displayed in the login window or upper-left corner of the Cisco ASDM window. Products Confirmed Not Vulnerable +-------------------------------- With the exception of the Cisco FWSM, no other Cisco products are currently known to be affected by these vulnerabilities. Note: Only transit traffic can trigger this vulnerability; traffic that is destined to the appliance will not trigger the vulnerability. MSN IM inspection is not enabled by default. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the ASA to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). The Cisco ASA supports TACACS+ authentication for VPN users, firewall sessions, and administrative access to the device. An authentication bypass vulnerability exists in the TACACS+ implementation of the Cisco ASA. Successful exploitation could allow a remote attacker to bypass TACACS+ authentication of VPN users, firewall sessions, or administrative access to the device. The attacker needs to have access to the network between the ASA and the TACACS+ server in order to successfully exploit this vulnerability. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The Sun RPC inspection engine performs application inspection for the Sun RPC protocol. Sun RPC is used by Network File System (NFS) and Network Information Service (NIS). Sun RPC services can run on any port. When a client attempts to access a Sun RPC service on a server, it must learn the port that service is running on. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. Note: Only transit traffic can trigger these vulnerabilities; traffic that is destined to the appliance will not trigger the vulnerabilities. These vulnerabilities can be triggered by using UDP packets, not TCP. SunRPC inspection is enabled by default. These vulnerabilities are documented in Cisco bug IDs CSCto92380, CSCtq06065, CSCtq06062, CSCto92398; and have been assigned CVE IDs CVE-2011-3299, CVE-2011-3300, CVE-2011-3301, and CVE-2010-3302, respectively. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- The ILS inspection engine provides NAT support for Microsoft NetMeeting, SiteServer, and Active Directory products that use LDAP to exchange directory information with an ILS server. Note: Only transit traffic can trigger this vulnerability; traffic that is destined to the appliance will not trigger the vulnerability. ILS inspection is not enabled by default.

Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of the vulnerabilities disclosed in this advisory. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. Refer to the "Software Version and Fixes" section for specific information on vulnerable versions. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if the following conditions are satisfied: * The device has interfaces with IPv6 addresses * System logging is enabled (command logging enable) * The device is configured in any way to generate system log message 302015 (refer to the following examples) System log message 302015 has a default severity level of 6 (informational) so, assuming that the system administrator has not changed this default severity level, the vulnerability can be triggered if the device is logging to any destination at level 6 or level 7 (debug). As an example, the following configuration is vulnerable: logging enable ! logging console informational logging buffered informational [...] Using a custom message list (via the logging list command) that includes system log message 302015, either by severity or by explicitly including the message ID, is also a vulnerable configuration. For example, the following configuration is also vulnerable: logging enable ! logging list MYLIST level informational <and/or> logging list MYLIST message 302015 ! logging trap MYLIST Note: The default severity level of system log messages can be changed. If the default severity level of system log message 302015 is changed, and the device is configured to log to any destination at the new severity level, then the device is still vulnerable. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use Authentication, Authorization, and Accounting (AAA) for network access, also known as cut-through or authentication proxy. The network access authentication feature is enabled if the aaa authentication match or aaa authentication include commands are present in the configuration of an affected device. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use the Terminal Access Controller Access-Control System Plus (TACACS+) protocol for AAA. A device is configured for TACACS+ if an AAA server group is defined in a manner similar to the following: aaa-server my-tacacs-server protocol tacacs+ aaa-server my-tacacs-server (inside) host 192.168.1.1 [...] Note: In the preceding example, "my-tacacs-server" is the name of the AAA server group. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if SunRPC inspection is enabled. SunRPC inspection is enabled by default. To determine whether SunRPC inspection is enabled, issue the show service-policy | include sunrpc command and confirm that the command returns output. Example output follows: FWSM# show service-policy | include sunrpc Inspect: sunrpc, packet 324, drop 5, reset-drop 0 Alternatively, a device with SunRPC inspection enabled has a configuration similar to the following (the inspect sunrpc command is the command that actually enables SunRPC inspection, although the other commands are necessary for the Cisco FWSM to actually inspect traffic): class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ! service-policy global_policy global Note: The service policy could also be applied to a specific interface. (Global application is shown in the previous example.) ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Devices running vulnerable versions of Cisco FWSM Software are affected by these vulnerabilities if inspection of the ILS protocol is enabled. ILS inspection is not enabled by default. Refer to "SunRPC Inspection Denial of Service Vulnerabilities" for information on how to determine if ILS inspection is enabled. Use the configuration keyword "ils" instead of "sunrpc". The following example shows a system with a Cisco FWSM (WS-SVC-FWM-1) installed in slot 2: switch>show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 16 SFM-capable 16 port 1000mb GBIC WS-X6516-GBIC SAL06334NS9 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 3 8 Intrusion Detection System WS-SVC-IDSM-2 SAD0932089Z 4 4 SLB Application Processor Complex WS-X6066-SLB-APC SAD093004BD 5 2 Supervisor Engine 720 (Active) WS-SUP720-3B SAL0934888E Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 0009.11e3.ade8 to 0009.11e3.adf7 5.1 6.3(1) 8.7(0.22)BUB Ok 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok 3 0014.a90c.9956 to 0014.a90c.995d 5.0 7.2(1) 7.0(4)E4 Ok 4 0014.a90c.66e6 to 0014.a90c.66ed 1.7 Unknown Unknown PwrDown 5 0013.c42e.7fe0 to 0013.c42e.7fe3 4.4 8.1(3) 12.2(33)SXH8 Ok [...] After locating the correct slot, issue the show module <slot number> command to identify the software version that is running, as shown in the following example: switch>show module 2 Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 2 6 Firewall Module WS-SVC-FWM-1 SAD10360485 Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 2 0018.ba41.5092 to 0018.ba41.5099 4.0 7.2(1) 4.0(16) Ok [...] The preceding example shows that the Cisco FWSM is running software version 4.0(16) as indicated by the Sw column. Note: Recent versions of Cisco IOS Software will show the software version of each module in the output from the show module command; therefore, executing the show module <slot number> command is not necessary. If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series switches to operate as a single logical virtual switch, the show module switch all command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from show module <slot number> but will include module information for the modules in each switch in the VSS. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- The Cisco FWSM has a system log (syslog) feature that provides information for monitoring normal operation and troubleshooting network or device issues. System log messages are assigned different severities (debugging, informational, error, critical, etc.) and can be sent to different logging destinations. A denial of service vulnerability exists in the implementation of one specific system log message (message ID 302015, "Built outbound UDP connection session-id for src-intf:IP/Port to dst-intf:IP/Port ARP-Incomplete") that can cause memory corruption and lead to a lock up or crash of the Cisco FWSM in the event that that system log message needs to be generated for IPv6 traffic that has flowed through the device. The Cisco FWSM may not recover on its own and a manual reboot may be necessary to recover. System log message 302015 has a default severity level of 6 (informational). Changing the default severity level of this system message will not prevent the issue from occurring if the system is logging to any destinations at the new severity level. The Cisco FWSM must have interfaces with IPv6 addresses otherwise the problem does not occur. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- The Cisco FWSM authentication proxy feature allows one to use AAA to control access to network resources. Specifically, the Cisco FWSM cut-through proxy challenges a user initially at the application layer and then authenticates against AAA servers. After the Cisco FWSM authenticates the user, it shifts the session flow, and all traffic flows directly between the user's computer and the network resource being accessed. A denial of service vulnerability exists in some versions of Cisco FWSM Software that affects devices configured to use authentication to grant users access to the network, also known as cut-through or authentication proxy. Vulnerable configurations are those that contain the aaa authentication match or aaa authentication include commands. The vulnerability may be triggered when there is a high number of network access authentication requests. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ AAA enables the Cisco FWSM to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). The Cisco FWSM supports TACACS+ authentication for VPN users, firewall sessions, and administrative access to the device. An authentication bypass vulnerability exists in the TACACS+ implementation in the Cisco FWSM. Successful exploitation could allow a remote attacker to bypass TACACS+ authentication of VPN users (the Cisco FWSM only allows VPN sessions for management), firewall sessions, or administrative access to the device. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- The SunRPC inspection engine enables or disables application inspection for the SunRPC protocol. SunRPC is used by Network File System (NFS) and Network Information Service (NIS). SunRPC services can run on any port. When a client attempts to access a SunRPC service on a server, it must learn the port on which the service is running. The client does this by querying the port mapper process, usually rpcbind, on the well-known port of 111. These vulnerabilities are triggered only by transit traffic; traffic that is destined to the device does not trigger these vulnerabilities. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- The ILS inspection engine provides Network Address Translation (NAT) support for Microsoft NetMeeting, SiteServer, and Active Directory products that use Lightweight Directory Access Protocol (LDAP) to exchange directory information with an ILS server. The Cisco FWSM is affected by a vulnerability when ILS inspection is enabled that may cause the device to reload during the processing of a malformed ILS message. This vulnerability is triggered by transit traffic only; traffic that is destined to the device does not trigger this vulnerability. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCti83875 -- Syslog message 302015 may lead to memory corruption and CP lockup CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtn15697 -- FWSM crash in thread name uauth CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCto74274 -- Crafted TACACS+ reply considered as successful auth by FWSM CVSS Base Score - 7.9 Access Vector - Adjacent Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * SunRPC Inspection Denial of Service Vulnerabilities CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtq57802 -- ILS inspection crash on malformed ILS traffic CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of any of the denial of service vulnerabilities could cause an affected device to reload. Repeated exploitation could result in a sustained denial of service condition. Successful exploitation of the TACACS+ authentication bypass vulnerability could allow an attacker to bypass authentication of VPN, firewall, and/or administrative sessions. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco FWSM Software table describes a major Cisco FWSM Software train and the earliest possible release in that train that contains the fix (the "First Fixed Release") and the anticipated date of availability (if not currently available) in the First Fixed Release column. A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. A vulnerable release should be upgraded to the indicated release at a minimum, or a later version (later than or equal to the First Fixed Release label). These vulnerabilities and their respective workarounds are independent of each other. Syslog Message Memory Corruption Denial of Service Vulnerability +--------------------------------------------------------------- Completely disabling syslog 302015 with the command no logging message 302015 is an effective workaround for this vulnerability. Authentication Proxy Denial of Service Vulnerability +--------------------------------------------------- There are no workarounds available for this vulnerability. TACACS+ Authentication Bypass Vulnerability +------------------------------------------ There are no workarounds available for this vulnerability other than using a different authentication protocol such as RADIUS and LDAP. SunRPC Inspection Denial of Service Vulnerabilities +-------------------------------------------------- Administrators can mitigate these vulnerabilities by disabling SunRPC inspection if it is not required. Administrators can disable SunRPC inspection by issuing the no inspect sunrpc command in class configuration sub-mode in the policy map configuration. Disabling SunRPC inspection may cause SunRPC traffic to stop transiting the security appliance. ILS Inspection Denial of Service Vulnerability +--------------------------------------------- Administrators can mitigate this vulnerability by disabling ILS inspection if it is not required. Administrators can disable ILS inspection by issuing the no inspect ils command in class configuration sub-mode in the policy map configuration. Disabling ILS inspection may cause ILS traffic to stop through the security appliance. Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased.

Please do not reply to this email address. HP Secure Web Server (SWS) for OpenVMS V2.2 and earlier. When using the RewriteRule or ProxyPassMatch directives to configure a reverse proxy using a pattern match, it is possible to inadvertently expose internal servers to remote users who send carefully crafted requests. The server did not validate that the input to the pattern match was a valid path string, so a pattern could expand to an unintended target URL. The documentation has been updated to reflect the more general risks with pattern matching in a reverse proxy configuration. Details: ======== A configuration like one of the following examples: RewriteRule (.*)\.(jpg|gif|png) http://images.example.com$1.$2 [P] ProxyPassMatch (.*)\.(jpg|gif|png) http://images.example.com$1.$2 could result in an exposure of internal servers. A request of the form: GET @other.example.com/something.png HTTP/1.1 would get translated to a target of: http://images.example.com@other.example.com/something.png This will cause the proxy to connect to the hostname "other.example.com", as the "images.example.com@" segment would be treated as user credentials when parsing the URL. This would allow a remote attacker the ability to proxy to hosts other than those expected, which could be a security exposure in some circumstances. The request-URI string in this example, "@other.example.com/something.png", is not valid according to the HTTP specification, since it neither an absolute URI ("http://example.com/path") nor an absolute path ("/path"). For future releases, the server has been patched to reject such requests, instead returning a "400 Bad Request" error. Actions: ======== Apache HTTPD users should examine their configuration files to determine if they have used an insecure configuration for reverse proxying. Affected users can update their configuration, or apply the patch from: http://www.apache.org/dist/httpd/patches/apply_to_2.2.21/ For example, the above RewriteRule could be changed to: RewriteRule /(.*)\.(jpg|gif|png) http://images.example.com/$1.$2 [P] to ensure the pattern only matches against paths with a leading "/".

Summary: Updated httpd packages that fix multiple security issues and one bug are now available for JBoss Enterprise Web Server 1.0.2 for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: JBoss Enterprise Web Server 1.0 for RHEL 5 Server - i386, x86_64 JBoss Enterprise Web Server 1.0 for RHEL 6 Server - i386, x86_64 3. It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. In certain configurations, if a reverse proxy used the ProxyPassMatch directive, or if it used the RewriteRule directive with the proxy flag, a remote attacker could make the proxy connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to the attacker. (CVE-2011-3368) It was discovered that mod_proxy_ajp incorrectly returned an "Internal Server Error" response when processing certain malformed HTTP requests, which caused the back-end server to be marked as failed in configurations where mod_proxy was used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period or until all back-end servers were marked as failed. (CVE-2011-3348) The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies. (CVE-2012-0053) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way httpd performed substitutions in regular expressions. An attacker able to set certain httpd settings, such as a user permitted to override the httpd configuration for a specific directory using a ".htaccess" file, could use this flaw to crash the httpd child process or, possibly, execute arbitrary code with the privileges of the "apache" user. (CVE-2011-3607) A NULL pointer dereference flaw was found in the httpd mod_log_config module. In configurations where cookie logging is enabled, a remote attacker could use this flaw to crash the httpd child process via an HTTP request with a malformed Cookie header. (CVE-2012-0021) A flaw was found in the way httpd handled child process status information. A malicious program running with httpd child process privileges (such as a PHP or CGI script) could use this flaw to cause the parent httpd process to crash during httpd service shutdown. (CVE-2012-0031) Red Hat would like to thank Context Information Security for reporting the CVE-2011-3368 issue. This update also fixes the following bug: * The fix for CVE-2011-3192 provided by the RHSA-2011:1329 update introduced a regression in the way httpd handled certain Range HTTP header values. This update corrects this regression. (BZ#749071) All users of JBoss Enterprise Web Server 1.0.2 should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, users must restart the httpd service for the update to take effect. 4.

The NAT implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 3.1.xSG, allows remote attackers to cause a denial of service (device reload or hang) via malformed NetMeeting Directory (aka Internet Locator Service or ILS) LDAP traffic, aka Bug ID CSCtd10712. Cisco IOS is prone to multiple remote denial-of-service vulnerabilities. An attacker can exploit these issues to cause an affected device to reload, denying service to legitimate users. These issues are being tracked by Cisco Bug IDs: CSCtd10712 CSCso02147 CSCti98219 CSCti48483 CSCtj04672 CSCth11006. For more information: SA46179 The vulnerabilities are reported in version 3.1.xSG. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Cisco Security Advisory: Cisco IOS Software Network Address Translation Vulnerabilities Advisory ID: cisco-sa-20110928-nat Revision 1.0 For Public Release 2011 Sep 28 1600 UTC (GMT) +-------------------------------------------------------------------- Summary ======= The Cisco IOS Software network address translation (NAT) feature contains multiple denial of service (DoS) vulnerabilities in the translation of the following protocols: * NetMeeting Directory (Lightweight Directory Access Protocol, LDAP) * Session Initiation Protocol (Multiple vulnerabilities) * H.323 protocol All the vulnerabilities described in this document are caused by packets in transit on the affected devices when those packets require application layer translation. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110928-nat.shtml. Note: The September 28, 2011, Cisco IOS Software Security Advisory bundled publication includes ten Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all vulnerabilities in the September 2011 Bundled Publication. Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep11.html Affected Products ================= Vulnerable Products +------------------ Cisco devices that are running Cisco IOS Software are vulnerable when they are configured for NAT and contain support for one or more of the following features: * NetMeeting Directory NAT (LDAP on TCP port 389) * NAT for Session Initiation Protocol (SIP) * NAT for H.323 The preferred method to verify whether NAT is enabled on a Cisco IOS device is to log in to the device and issue the "show ip nat statistics" command. If NAT is active the sections Outside interfaces and Inside interfaces will each include at least one interface. The following example shows a device on which the NAT feature is active: Router#show ip nat statistics Total translations: 2 (0 static, 2 dynamic; 0 extended) Outside interfaces: Serial0 Inside interfaces: Ethernet1 Hits: 135 Misses: 5 Expired translations: 2 Dynamic mappings: -- Inside Source access-list 1 pool mypool refcount 2 pool mypool: netmask 255.255.255.0 start 192.168.10.1 end 192.168.10.254 type generic, total addresses 14, allocated 2 (14%), misses 0 Depending on the Cisco IOS Software release, the interface lists can be in the lines following the Outside interfaces and Inside interfaces lines. In releases that support the section filter on show commands, the administrator can determine whether NAT is active by using the "show ip nat statistics | section interfaces" command: Router> show ip nat statistics | section interfaces Outside interfaces: GigabitEthernet0/0 Inside interfaces: GigabitEthernet0/1 Router> Alternatively, to determine whether NAT has been enabled in the Cisco IOS Software configuration, either the "ip nat inside" and "ip nat outside" commands must be present in different interfaces or, in the case of the NAT Virtual Interface, the "ip nat enable" interface command will be present. To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the "show version" command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the "show version" command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 15.0(1)M1 with an installed image name of C3900-UNIVERSALK9-M: Router> show version Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team !--- output truncated Additional information about Cisco IOS Software release naming conventions is available in White Paper: Cisco IOS and NX-OS Software Reference Guide. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= NAT for NetMeeting Directory (LDAP) Vulnerability +------------------------------------------------ LDAP is a protocol for querying and modifying data of directory services implemented in IP networks. NAT for NetMeeting Directory, also known as the Internet Locator Service (ILS), translates LDAP packets on TCP port 389. The inspected port is not configurable. This vulnerability is triggered by malformed transit LDAP traffic that needs to be processed by the NAT for NetMeeting Directory feature. This vulnerability is documented in Cisco bug ID CSCtd10712 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0946. NAT for SIP DoS Vulnerabilities +------------------------------ Four vulnerabilities in the NAT for SIP feature are described in this document: NAT of SIP over TCP vulnerability: Crafted SIP packets on TCP port 5060 could cause unpredictable results, including the reload of the vulnerable device. Translation of SIP over TCP packets will be disabled by default with the fix for this vulnerability. This vulnerability is documented in Cisco bug ID CSCso02147 and has been assigned Common Vulnerabilities and Exposures CVE-2011-3276. Provider edge Multiprotocol Label Switching (MPLS) NAT of SIP over UDP packets DoS vulnerability: A malformed SIP packet on UDP 5060 that transits an MPLS enabled vulnerable device that needs an MPLS tag to be imposed on the malformed packet might reload the device. NAT of crafted SIP over UDP packets DoS vulnerabilities: There are two DoS vulnerabilities related to similar crafted packets on UDP port 5060 that require SIP translation: the first is a vulnerability that will cause the device to reload and the second will cause a memory leak that could lead to a DoS condition, including reload of the vulnerable device. They have been assigned CVE IDs CVE-2011-3278 and CVE-2011-3280. NAT of H.323 Packets DoS Vulnerability +------------------------------------- Transit crafted H.323 packets on TCP port 1720 could cause a reload of the vulnerable device. This vulnerability is documented in Cisco bug ID CSCth11006 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-3277. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCtd10712 ("NAT LDAP Vulnerability") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCso02147 ("NAT of SIP over TCP Vulnerability") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCti98219 ("Provider-Edge MPLS NAT of SIP over UDP packets Vulnerability") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCti48483/CSCtj04672 ("NAT of crafted SIP packets vulnerabilities") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCth11006 ("NAT of H.323 Packets DoS Vulnerability") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of these vulnerabilities can cause the device to reload or become unresponsive. For the NAT of UDP over SIP vulnerability that corresponds to Cisco bug CSCtj04672, it is also possible that exploitation can cause a memory leak. Repeated exploitation of the memory leak vulnerability can lead to a DoS condition in which the device reloads or becomes unresponsive. Reloading may occur automatically, or the device may require manual intervention to reload.

Cisco IOS XR Software +-------------------- Cisco IOS XR Software is not affected by any of the vulnerabilities in the September 2011 bundled publication. Workarounds =========== It is possible to mitigate the vulnerabilities in this advisory by disabling the translation of embedded IP addresses in the payload of IP packets. Disabling NAT for the different protocols requires different configurations. For some protocols, a single command can be used. Other protocols require individual NAT translation rules be added to the configuration. NAT LDAP Vulnerability Mitigation +--------------------------------- To disable NAT of LDAP, port-based address translation needs to be configured to disable LDAP inspection using the no-payload keyword. This will still allow the NAT of LDAP packets at Layer 3 (non-port specific). Translation of other non-LDAP protocols translation will not be affected. Applications that use embedded IP addresses in LDAP, such as NetMeeting Directory, will be negatively impacted if the embedded IP addresses need to be translated. The following is an example configuration that includes the mitigation for two NAT rules. !-- NAT rule for port TCP/389 to disable IP NAT for LDAP translation !-- Takes precedence over the non-port translation rule. ip nat outside source static tcp 192.168.0.1 389 192.168.1.1 389 no-payload ip nat outside source static tcp 192.168.0.3 389 192.168.1.3 389 no-payload !-- Translation rule for all other protocols ip nat outside source static 192.168.0.1 192.168.1.1 ip nat outside source static 192.168.0.3 192.168.1.3 interface GigabitEthernet0/0 ip nat inside interface GigabitEthernet0/1 ip nat outside Each NAT translation rule in the configuration will need to be updated to include a per-port rule that disables translation of TCP packets on port 389. NAT for SIP over TCP DoS Vulnerability Mitigation +------------------------------------------------ Mitigation for this vulnerability consists of disabling NAT for SIP over the TCP transport by using the "no ip nat service sip tcp port 5060" global configuration command. NAT of Crafted SIP over UDP Packets DoS Vulnerability Mitigation +--------------------------------------------------------------- Mitigation of these vulnerabilities consists of disabling NAT for SIP over the UDP transport by using the "no ip nat service sip udp port 5060" global configuration command. NAT for Crafted H.323 Packets DoS Vulnerability Mitigation +--------------------------------------------------------- Mitigation for this vulnerability consists of disabling NAT for H.323 and H.225.0 using the "no ip nat service h225" global configuration command.

These vulnerabilities are: * Memory leak in Cisco IOS Software * Cisco IOS Software Denial of Service when processing specially crafted HTTP packets Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are not available. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110928-zbfw.shtml. Note: The September 28, 2011, Cisco IOS Software Security Advisory bundled publication includes ten Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all vulnerabilities in the September 2011 Bundled Publication. The two vulnerabilities are independent of each other. Details to confirm affected configurations are provided below. To determine if a device is configured with Cisco IOS IPS, log into the device and issue the "show ip ips interfaces" CLI command. If the output shows an IPS rule either in the inbound or outbound direction set, then the device is vulnerable. This example, shows a device with an IPS rule set on Interface Gigabit Ethernet 0/0 in the inbound direction: Router#show ip ips interfaces Interface Configuration Interface GigabitEthernet0/0 Inbound IPS rule is example_ips_rule Outgoing IPS rule is not set Router# A device that is not configured for Cisco IOS IPS will return a blank line. The following example shows a device on which Cisco IOS IPS is not configured: Router#show ip ips interfaces Router# To determine whether a device is configured with Zone-Based Firewall, log into the device and issue the "show zone security" CLI command. If the output shows a member interface under a zone name, then the device is vulnerable. This example, shows a device with Zone-Based Firewall rules configured on both GigabitEthernet0/0 and GigabitEthernet0/1 Router#show zone security zone self Description: System defined zone zone inside Description: *** Inside Network *** Member Interfaces: GigabitEthernet0/0 zone outside Description: *** Outside Network *** Member Interfaces: GigabitEthernet0/1 Router# Note: The device is vulnerable if configured with Zone-Based Firewall, regardless of the type of packet inspection being performed. * Cisco IOS Software Denial of Service when processing specially crafted HTTP packets A device is vulnerable if configured under the following circumstances: - HTTP Layer 7 Application Control and Inspection and Cisco IOS IPS are enabled. - HTTP Layer 7 Application Control and Inspection with match request arg regex parameter on the HTTP class map. This configuration is affected regardless if Cisco IOS IPS is enabled or not. The device is not vulnerable under other configurations. A summary of different configurations and their affect by this vulnerability is provided below: +--------------------------------------------------------+ | | Affected | | Configuration on Device | or not | | | Affected | |--------------------------------------------+-----------| | Only Cisco IOS IPS enabled | Not | | | Affected | |--------------------------------------------+-----------| | HTTP Layer 4 Stateful Inspection with | Not | | Cisco IOS IPS enabled | Affected | |--------------------------------------------+-----------| | HTTP Layer 4 Stateful Inspection with | Not | | Cisco IOS IPS disabled | Affected | |--------------------------------------------+-----------| | HTTP Layer 7 Application Control and | Affected | | Inspection with Cisco IOS IPS enabled | | |--------------------------------------------+-----------| | HTTP Layer 7 Application Control and | | | Inspection with match arg regex parameter. | Affected | | With or without Cisco IOS IPS enabled. | | |--------------------------------------------+-----------| | HTTP Layer 7 Application Control and | | | Inspection without match arg regex | Not | | parameter.

Workarounds =========== Workarounds that mitigate these vulnerabilities are not available. Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml. Do not contact psirt@cisco.com or security-alert@cisco.com for software upgrades. Customers with Service Contracts +------------------------------- Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com. Customers using Third Party Support Organizations +------------------------------------------------ Customers whose Cisco products are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory. The effectiveness of any workaround or fix is dependent on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed. Customers without Service Contracts +---------------------------------- Customers who purchase direct from Cisco but do not hold a Cisco service contract, and customers who purchase through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should acquire upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com Customers should have their product serial number available and be prepared to give the URL of this notice as evidence of entitlement to a free upgrade.
