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.

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. 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.

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.

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. 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.

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.

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. 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.

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.

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.

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.

The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character. Apache HTTP Server is prone to an information disclosure vulnerability. An attacker can exploit this vulnerability to gain access to sensitive information. Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker might obtain sensitive information, gain privileges, send requests to unintended servers behind proxies, bypass certain security restrictions, obtain the values of HTTPOnly cookies, or cause a Denial of Service in various ways.

This could allow remote attackers to contact internal webservers behind the proxy that were not intended for external exposure. (CVE-2011-3348) Samuel Montosa discovered that the ITK Multi-Processing Module for Apache did not properly handle certain configuration sections that specify NiceValue but not AssignUserID, preventing Apache from dropping privileges correctly. This issue only affected Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-1176) USN 1199-1 fixed a vulnerability in the byterange filter of Apache. The upstream patch introduced a regression in Apache when handling specific byte range requests. Original advisory details: A flaw was discovered in the byterange filter in Apache. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: apache2.2-bin 2.2.20-1ubuntu1.1 Ubuntu 11.04: apache2-mpm-itk 2.2.17-1ubuntu1.4 apache2.2-bin 2.2.17-1ubuntu1.4 Ubuntu 10.10: apache2-mpm-itk 2.2.16-1ubuntu3.4 apache2.2-bin 2.2.16-1ubuntu3.4 Ubuntu 10.04 LTS: apache2-mpm-itk 2.2.14-5ubuntu8.7 apache2.2-bin 2.2.14-5ubuntu8.7 Ubuntu 8.04 LTS: apache2.2-common 2.2.8-1ubuntu0.22 In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd security and bug fix update Advisory ID: RHSA-2012:0543-01 Product: JBoss Enterprise Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0543.html Issue date: 2012-05-07 CVE Names: CVE-2011-3348 CVE-2011-3368 CVE-2011-3607 CVE-2012-0021 CVE-2012-0031 CVE-2012-0053 ===================================================================== 1. Summary: An update for the Apache HTTP Server component for JBoss Enterprise Web Server 1.0.2 that fixes multiple security issues and one bug is now available from the Red Hat Customer Portal. 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. 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-2011:1330 update introduced a regression in the way httpd handled certain Range HTTP header values.

This version of Apache is principally a security and bug fix release, including the following significant security fixes: * SECURITY: CVE-2011-3368 (cve.mitre.org) Reject requests where the request-URI does not match the HTTP specification, preventing unexpected expansion of target URLs in some reverse proxy configurations. * SECURITY: CVE-2011-3607 (cve.mitre.org) Fix integer overflow in ap_pregsub() which, when the mod_setenvif module is enabled, could allow local users to gain privileges via a .htaccess file. * SECURITY: CVE-2011-4317 (cve.mitre.org) Resolve additional cases of URL rewriting with ProxyPassMatch or RewriteRule, where particular request-URIs could result in undesired backend network exposure in some configurations. * SECURITY: CVE-2012-0021 (cve.mitre.org) mod_log_config: Fix segfault (crash) when the '%{cookiename}C' log format string is in use and a client sends a nameless, valueless cookie, causing a denial of service. The issue existed since version 2.2.17. * SECURITY: CVE-2012-0053 (cve.mitre.org) Fixed an issue in error responses that could expose "httpOnly" cookies when no custom ErrorDocument is specified for status code 400. The Apache HTTP Project thanks halfdog, Context Information Security Ltd, Prutha Parikh of Qualys, and Norman Hippert for bringing these issues to the attention of the security team. We consider this release to be the best version of Apache available, and encourage users of all prior versions to upgrade. Apache HTTP Server 2.2.22 is available for download from: http://httpd.apache.org/download.cgi Please see the CHANGES_2.2 file, linked from the download page, for a full list of changes. A condensed list, CHANGES_2.2.22 includes only those changes introduced since the prior 2.2 release. A summary of all of the security vulnerabilities addressed in this and earlier releases is available: http://httpd.apache.org/security/vulnerabilities_22.html This release includes the Apache Portable Runtime (APR) version 1.4.5 and APR Utility Library (APR-util) version 1.4.2, bundled with the tar and zip distributions. The APR libraries libapr and libaprutil (and on Win32, libapriconv version 1.2.1) must all be updated to ensure binary compatibility and address many known security and platform bugs. APR-util version 1.4 represents a minor version upgrade from earlier httpd source distributions, which previously included version 1.3. Apache 2.2 offers numerous enhancements, improvements, and performance boosts over the 2.0 codebase. For an overview of new features introduced since 2.0 please see: http://httpd.apache.org/docs/2.2/new_features_2_2.html This release builds on and extends the Apache 2.0 API. Modules written for Apache 2.0 will need to be recompiled in order to run with Apache 2.2, and require minimal or no source code changes. http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/VERSIONING When upgrading or installing this version of Apache, please bear in mind that if you intend to use Apache with one of the threaded MPMs (other than the Prefork MPM), you must ensure that any modules you will be using (and the libraries they depend on) are thread-safe. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c03231301 Version: 1 HPSBMU02748 SSRT100772 rev.1 - HP OpenView Network Node Manager (OV NNM) Running Apache HTTP Server, Remote Unauthorized Disclosure of Information, Unauthorized Modification, Denial of Service (DoS) NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.
