To successfully exploit the vulnerability, an attacker must send a specially crafted request to the affected device TCP 80, 443 or 8080. Cisco TelePresence Multipoint Switch is prone to multiple vulnerabilities, including: 1. Multiple denial-of-service vulnerabilities 2. A security-bypass vulnerability 3. An unauthorized-access vulnerability An attacker can exploit these issues to bypass certain security restrictions and cause a denial-of-service condition. Other attacks are also possible. These issues are being tracked by the following Cisco Bug IDs: CSCtf01253 CSCtf97164 CSCth60993 CSCtj44534. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect.

An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. This vulnerability could allow an unauthenticated, adjacent attacker to trigger a buffer overflow condition. To exploit this vulnerability, the attacker must submit a malicious Cisco Discovery Protocol packet to the affected system. Because Cisco Discovery Protocol works at the data-link layer (Layer 2), an attacker must have a way to submit an Ethernet frame directly to an affected device. This may be possible in situations where the affected system is part of a bridged network or connected to a nonpartitioned device such as a network hub. The vulnerability could allow an unauthenticated, remote attacker to cause all recording and playback threads on the device to be consumed. A restart of the affected device may be required to regain functionality. To successfully exploit this vulnerability the attacker would need the ability to submit a malformed request to an affected device via TCP port 80. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. Java RMI Denial of Service +------------------------- A denial of service vulnerability exists within Cisco TelePresence Recording Server devices due to a failure to properly restrict access to the RMI interface of the Java Servlet framework. An unauthenticated, remote attacker could trigger an out-of-memory condition on the Servlet host by issuing a series of crafted requests. To successfully exploit this vulnerability the attacker would need the ability to communicate to an affected device on TCP port 8999. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. This vulnerability could allow an unauthenticated, remote attacker to perform a limited number of actions on the system that should be restricted to authorized users.

The defect that is related to each component is covered in each associated advisory. The defect that is related to each component is covered in each associated advisory. To determine the current version of software that is running on the Cisco TelePresence Recording Server, SSH into the device and issue the show version active and the show version inactive commands. The output should resemble the following example: admin: show version active Active Master Version: 1.7.0.0-151 Active Version Installed Software Options: No Installed Software Options Found. admin: show version inactive Inactive Master Version: 1.6.2.0-237 Inactive Version Installed Software Options: No Installed Software Options Found. In the preceding example, the system has versions 1.6.2 and 1.7.0 loaded on the device and version 1.7.0 is currently active. A device is affected only by vulnerabilities that are present in the active software version. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. These vulnerabilities are independent of each other. Unauthenticated Java Servlet Access +---------------------------------- A number of sensitive Java Servlets delivered via a Java Servlet framework within the Cisco TelePresence Recording Server could allow a remote, unauthenticated attacker to perform actions that should be restricted to administrative users. To successfully exploit this vulnerability, the attacker would need the ability to submit a crafted request to an affected device on TCP port 80, TCP port 443, or TCP port 8080. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities. CGI Command Injection +-------------------- A CGI command injection vulnerability exists within the Cisco TelePresence Recording Server that could allow a remote, unauthenticated attacker to execute arbitrary commands with elevated privileges. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities. An unauthenticated, remote attacker could place content to arbitrary locations on the device by submitting crafted requests to the affected device. To successfully exploit this vulnerability the attacker would need the ability to submit a crafted request to an affected device on TCP port 80 or 443. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. XML-RPC Arbitrary File Overwrite +------------------------------- An arbitrary file overwrite vulnerability exists within Cisco TelePresence Recording Server devices that could allow an unauthenticated, remote attacker to overwrite arbitrary files with logging data. This vulnerability could be leveraged to obtain full control of the affected device. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. This vulnerability could allow an unauthenticated, adjacent attacker to trigger a buffer overflow condition. To exploit this vulnerability, the attacker must submit a malicious Cisco Discovery Protocol packet to the affected system. Because Cisco Discovery Protocol works at the data-link layer (Layer 2), an attacker must have a way to submit an Ethernet frame directly to an affected device. This may be possible in situations where the affected system is part of a bridged network or connected to a nonpartitioned device such as a network hub. A restart of the affected device may be required to regain functionality. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. An unauthenticated, remote attacker could trigger an out-of-memory condition on the Servlet host by issuing a series of crafted requests. To successfully exploit this vulnerability the attacker would need the ability to communicate to an affected device on TCP port 8999. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. This vulnerability could allow an unauthenticated, remote attacker to perform a limited number of actions on the system that should be restricted to authorized users. To successfully exploit this vulnerability the attacker would need the ability to communicate to an affected device on TCP port 8080. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability.

Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities Details ======= The Cisco TelePresence solution allows for immersive, in-person communication and collaboration over the network with colleagues, prospects, and partners even when they are located in opposite hemispheres. Unauthenticated Java Servlet Access +---------------------------------- A number of sensitive Java Servlets delivered via a Java Servlet framework in the Cisco Telepresence Multipoint Switch could allow a remote, unauthenticated attacker to perform actions that should be restricted to administrative users only. The attacker would need the ability to submit a crafted request to an affected device on TCP port 80, 443, or 8080. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities. * CTMS - CSCtf42008 ( registered customers only) has been assigned the CVE identifier CVE-2011-0383. * CTMS - CSCtf01253 ( registered customers only) has been assigned the CVE identifier CVE-2011-0384. An unauthenticated, remote attacker could submit a crafted request to an affected device that would allow for the placement of attacker-controlled content in arbitrary locations on the device. The attacker would need the ability to submit a crafted request to an affected device on TCP port 80 or 443. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. * CTMS - CSCth61065 ( registered customers only) has been assigned the CVE identifier CVE-2011-0385. An unauthenticated, adjacent attacker could exploit the vulnerability by submitting a malicious Cisco Discovery Protocol packet to the affected system. When parsed, the malicious packet may trigger a buffer overflow. Because Cisco Discovery Protocol works at the data link layer (Layer 2), an attacker must have a way to submit an Ethernet frame directly to an affected device. This may be possible in situations where the affected system is part of a bridged network or connected to a nonpartitioned device such as a network hub. * CTMS - CSCtd75766 ( registered customers only) has been assigned the CVE identifier CVE-2011-0379. Unauthorized Servlet Access +-------------------------- An unauthorized servlet access issue exists in the administrative web interface of Cisco TelePresence Multipoint Switch devices. The attacker would need the ability to submit a crafted request to an affected device on TCP port 80 or 443. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. * CTMS - CSCtf97164 ( registered customers only) has been assigned the CVE identifier CVE-2011-0387. An unauthenticated, remote attacker could trigger an out-of-memory condition on the servlet host by issuing a series of crafted requests. The attacker would need the ability to communicate to an affected device on TCP port 8999. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. * CTMS - CSCtg35825 ( registered customers only) has been assigned the CVE identifier CVE-2011-0388. An unauthenticated, remote attacker could send a malicious RTCP packet to a listening RTCP control port to crash the call control process. The attacker would need to have the ability to communicate to an affected device on a UDP port that was randomly selected and negotiated during call setup. Because the vulnerability is within a UDP-based service, the attacker would not be required to perform a handshake prior to making the crafted request. This could allow the attacker to spoof the source address of an attack. * CTMS - CSCth60993 ( registered customers only) has been assigned the CVE identifier CVE-2011-0389. A remote, unauthenticated attacker could send a malicious request to an affected device to trigger a crash of the call geometry process. The attacker would need the ability to communicate to an affected device on TCP port 9000. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. * CTMS - CSCtj44534 ( registered customers only) has been assigned the CVE identifier CVE-2011-0390.

The CGI implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.5.x allows remote attackers to execute arbitrary commands via a malformed request, related to "command injection vulnerabilities," aka Bug ID CSCtb31640. The problem is Bug ID CSCtb31640 It is a problem.Arbitrary commands may be executed by a third party via a malformed request. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. To exploit these vulnerabilities, an attacker must send a malformed request to the affected device's TCP port 8082. Cisco TelePresence endpoint devices are prone to multiple vulnerabilities. An attacker can exploit these issues to execute arbitrary commands, disclose potentially sensitive information, or cause denial-of-service conditions. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. The defect that is related to each component is covered in each associated advisory. To determine the current version of software that is running on the endpoint, access the device via SSH and issue the show version command. The output should resemble the following example. The version that is active on the system will be marked by an asterisk character (*). admin: show version primary Factory CTS 1.4.2(2194) *Slot 1 CTS 1.7.1(4750) P1 Slot 2 CTS 1.6.2(2835) P1 admin: In the preceding example, the system has versions 1.4.2, 1.6.2, and 1.7.1 loaded on the device and version 1.7.1 is currently active. A device is affected only by vulnerabilities that are present in the active software version. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco TelePresence solution allows for immersive, in-person communication and collaboration over the network with colleagues, prospects, and partners even when they are located in opposite hemispheres. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities: * Cisco TelePresence endpoint - CSCtb31685 ( registered customers only) has been assigned the CVE identifier CVE-2011-0373. Because the vulnerability is within a UDP based service, the attacker would not be required to perform a handshake prior to making the crafted request. However, due to the fact that this is an information disclosure issue the attacker would need to supply a valid return IP address to retrieve the information. An attacker with the ability to impersonate a Cisco TelePresence Manager system could remotely inject an invalid IP address into a configuration file that could cause a critical service on the device to crash. An endpoint affected by this issue will remain unusable until it has been manually restored to a known good state. Restoration of service may require an administrator to reload software on the affected device. The issue may require that the attacker perform an ARP spoofing or other form of impersonation attack. This vulnerability could allow an unauthenticated, adjacent attacker to trigger a buffer overflow condition. Because Cisco Discovery Protocol functions at the Data-Link (L2) layer, an attacker must submit an Ethernet frame directly to an affected device. This scenario may be possible when affected systems are part of a bridged network or connected to a nonpartitioned device such as a network hub. 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 Cisco Security Advisory is done in accordance with CVSS version 2.0.

Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 7.0 before 7.0(8.12), 7.1 and 7.2 before 7.2(5.2), 8.0 before 8.0(5.21), 8.1 before 8.1(2.49), 8.2 before 8.2(3.6), and 8.3 before 8.3(2.7) and Cisco PIX Security Appliances 500 series devices, when transparent firewall mode is configured but IPv6 is not configured, allow remote attackers to cause a denial of service (packet buffer exhaustion and device outage) via IPv6 traffic, aka Bug ID CSCtj04707. The problem is Bug ID CSCtj04707 It is a problem.By a third party IPv6 Service disruption through traffic (DoS) There is a possibility of being put into a state. When the security application device receives IPv6 communication but does not configure IPv6 operation, the number of available message buffers is reduced. IPv6 transit communication does not cause this problem. The administrator can submit the show blocks command to check the message buffer utilization. If the number of blocks is 0, the application device is affected by this vulnerability: ciscoasa# show blocks SIZE MAX LOW CNT 0 400 360 400 4 200 199 199 80 400 358 400 256 1412 1381 1412 1550 6274 0 0 ... An attacker can exploit these issues to disclose potentially sensitive information or to cause denial-of-service conditions. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110223-asa.shtml. Note: The Cisco Firewall Services Module (FWSM) is affected by one of these vulnerabilities. A separate Cisco Security Advisory has been published to disclose the vulnerability that affects the Cisco FWSM. That advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20110223-fwsm.shtml. Affected versions of Cisco ASA Software vary depending on the specific vulnerability. Vulnerable Products +------------------ For specific version information, refer to the Software Versions and Fixes section of this advisory. Transparent firewall mode is enabled on the appliance if the command "firewall transparent" is present in the configuration. The default firewall mode is routed, not transparent. Administrators can determine if SCCP inspection is enabled by issuing the "show service-policy | include skinny" command and confirming that output, such as what is displayed in the following example, is returned. ciscoasa# show service-policy | include skinny Inspect: skinny, packet 0, drop 0, reset-drop 0 Alternatively, a device that has SCCP inspection enabled has a configuration similar to the following: class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect skinny ... ! service-policy global_policy global Note: The service policy could also be applied to a specific interface instead of globally, which is displayed in the previous example. SCCP inspection is enabled by default. The following example displays an affected configuration (Cisco ASA Software version 8.0 and 8.1): router rip ... ! phone-proxy <instance name> media-termination address <IP address> ... <Rest of phone proxy feature configuration> Or (Cisco ASA Software version 8.2 and later): router rip ... ! media-termination <instance name> address <IP address> ! <Rest of phone proxy feature configuration> A security appliance is vulnerable if it is processing RIP messages ("router rip") and if a global media termination address is configured for the Cisco Phone Proxy feature (refer to previous example). Note that Cisco ASA Software versions 8.0 and 8.1 only allow a global media termination address. However, in Cisco ASA Software version 8.2 and later, it is possible to tie a media termination address to an interface. This configuration, which is accomplished by issuing the command "address <IP address> interface <interface name>" in media termination configuration mode, is not affected. Neither RIP nor the Cisco Phone Proxy feature is enabled by default. An affected configuration consists of the following minimum commands: crypto ca trustpoint <trustpoint name> keypair <keypair name> crl configure crypto ca server crypto ca certificate chain <trustpoint name> certificate ca 01 ... ! http server enable The local CA server is not enabled by default. Because Cisco PIX 500 Series Security Appliances reached the end of software maintenance releases milestone on July 28, 2009, no further software releases will be available. For more information, refer to the End of Life announcement at http://www.cisco.com/en/US/prod/collateral/vpndevc/ps5708/ps5709/ps2030/end_of_life_notice_cisco_pix_525_sec_app.html. How to Determine Software Versions +--------------------------------- To determine whether a vulnerable version of Cisco ASA Software is running on an appliance, administrators can issue the "show version" command. It offers firewall, intrusion prevention system (IPS), anti-X, and virtual private network (VPN) services. This vulnerability is documented in Cisco bug ID CSCtj04707 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0393. Appliances are only vulnerable if SCCP inspection is enabled. Only transit traffic can trigger this vulnerability; traffic that is destined to the appliance will not trigger the vulnerability. This vulnerability is documented in Cisco bug ID CSCtg69457 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0394. Appliances are vulnerable only if both RIP and the Cisco Phone Proxy feature are enabled. Note: the affected configuration requires that a global media termination address is configured, which is the only possible configuration option in Cisco ASA Software versions 8.0 and 8.1. However, it is possible to tie a media termination address to an interface in Cisco ASA Software version 8.2 and later. This configuration is not vulnerable. This vulnerability is documented in Cisco bug ID CSCtg66583 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0395. but not system:) when the security appliance is configured as a local CA server. No authentication is required. File systems could contain sensitive information, such as backup device configurations (which may contain passwords or shared secrets), Cisco ASA Software images, or digital certificates. This vulnerability is documented in Cisco bug ID CSCtk12352 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0396.

The problem is Bug ID CSCtg66583 It is a problem.By a third party RIP Service disruption through updates (DoS) There is a possibility of being put into a state. The Cisco Adaptive Security Appliance is an adaptive security appliance that provides modules for security and VPN services. Cisco ASA 5500 series security appliances are prone to multiple remote vulnerabilities. An attacker can exploit these issues to disclose potentially sensitive information or to cause denial-of-service conditions. FWSM is a firewall service module. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110223-asa.shtml. A separate Cisco Security Advisory has been published to disclose the vulnerability that affects the Cisco FWSM. That advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20110223-fwsm.shtml. Vulnerable Products +------------------ For specific version information, refer to the Software Versions and Fixes section of this advisory. Transparent Firewall Packet Buffer Exhaustion Vulnerability +---------------------------------------------------------- A packet buffer exhaustion vulnerability affects multiple versions of Cisco ASA Software when a security appliance is configured to operate in the transparent firewall mode. Transparent firewall mode is enabled on the appliance if the command "firewall transparent" is present in the configuration. The default firewall mode is routed, not transparent. Administrators can determine if SCCP inspection is enabled by issuing the "show service-policy | include skinny" command and confirming that output, such as what is displayed in the following example, is returned. ciscoasa# show service-policy | include skinny Inspect: skinny, packet 0, drop 0, reset-drop 0 Alternatively, a device that has SCCP inspection enabled has a configuration similar to the following: class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect skinny ... ! service-policy global_policy global Note: The service policy could also be applied to a specific interface instead of globally, which is displayed in the previous example. SCCP inspection is enabled by default. The following example displays an affected configuration (Cisco ASA Software version 8.0 and 8.1): router rip ... ! phone-proxy <instance name> media-termination address <IP address> ... ! media-termination <instance name> address <IP address> ! <Rest of phone proxy feature configuration> A security appliance is vulnerable if it is processing RIP messages ("router rip") and if a global media termination address is configured for the Cisco Phone Proxy feature (refer to previous example). Note that Cisco ASA Software versions 8.0 and 8.1 only allow a global media termination address. However, in Cisco ASA Software version 8.2 and later, it is possible to tie a media termination address to an interface. This configuration, which is accomplished by issuing the command "address <IP address> interface <interface name>" in media termination configuration mode, is not affected. An affected configuration consists of the following minimum commands: crypto ca trustpoint <trustpoint name> keypair <keypair name> crl configure crypto ca server crypto ca certificate chain <trustpoint name> certificate ca 01 ... ! http server enable The local CA server is not enabled by default. Because Cisco PIX 500 Series Security Appliances reached the end of software maintenance releases milestone on July 28, 2009, no further software releases will be available. For more information, refer to the End of Life announcement at http://www.cisco.com/en/US/prod/collateral/vpndevc/ps5708/ps5709/ps2030/end_of_life_notice_cisco_pix_525_sec_app.html. How to Determine Software Versions +--------------------------------- To determine whether a vulnerable version of Cisco ASA Software is running on an appliance, administrators can issue the "show version" command. It offers firewall, intrusion prevention system (IPS), anti-X, and virtual private network (VPN) services. The number of available packet buffers may decrease when a security appliance receives IPv6 traffic and is not configured for IPv6 operation. IPv6 transit traffic does not cause a problem. Administrators can check packet buffer utilization by issuing the command "show blocks" and inspecting the output for the number of available 1,550-byte blocks. If the number of blocks is zero (indicated by 0 in the CNT column), then the security appliance may be experiencing this issue. For example: ciscoasa# show blocks SIZE MAX LOW CNT 0 400 360 400 4 200 199 199 80 400 358 400 256 1412 1381 1412 1550 6274 0 0 ... This vulnerability is documented in Cisco bug ID CSCtj04707 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0393. Appliances are only vulnerable if SCCP inspection is enabled. Only transit traffic can trigger this vulnerability; traffic that is destined to the appliance will not trigger the vulnerability. This vulnerability is documented in Cisco bug ID CSCtg69457 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0394. Note: the affected configuration requires that a global media termination address is configured, which is the only possible configuration option in Cisco ASA Software versions 8.0 and 8.1. However, it is possible to tie a media termination address to an interface in Cisco ASA Software version 8.2 and later. This configuration is not vulnerable. This vulnerability is documented in Cisco bug ID CSCtg66583 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0395. but not system:) when the security appliance is configured as a local CA server. No authentication is required. File systems could contain sensitive information, such as backup device configurations (which may contain passwords or shared secrets), Cisco ASA Software images, or digital certificates. This vulnerability is documented in Cisco bug ID CSCtk12352 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0396.

Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 8.0 before 8.0(5.23), 8.1 before 8.1(2.49), 8.2 before 8.2(4.1), and 8.3 before 8.3(2.13), when a Certificate Authority (CA) is configured, allow remote attackers to read arbitrary files via unspecified vectors, aka Bug ID CSCtk12352. The problem is Bug ID CSCtk12352 It is a problem.A third party may be able to read arbitrary files. The Cisco Adaptive Security Appliance is an adaptive security appliance that provides modules for security and VPN services. The file system contains sensitive information such as backup device configuration (which may include a password or shared secret), Cisco ASA software image or digital certificate. An attacker can exploit these issues to disclose potentially sensitive information or to cause denial-of-service conditions. FWSM is a firewall service module. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110223-asa.shtml. Note: The Cisco Firewall Services Module (FWSM) is affected by one of these vulnerabilities. A separate Cisco Security Advisory has been published to disclose the vulnerability that affects the Cisco FWSM. That advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20110223-fwsm.shtml. Affected versions of Cisco ASA Software vary depending on the specific vulnerability. Vulnerable Products +------------------ For specific version information, refer to the Software Versions and Fixes section of this advisory. Transparent Firewall Packet Buffer Exhaustion Vulnerability +---------------------------------------------------------- A packet buffer exhaustion vulnerability affects multiple versions of Cisco ASA Software when a security appliance is configured to operate in the transparent firewall mode. Transparent firewall mode is enabled on the appliance if the command "firewall transparent" is present in the configuration. The default firewall mode is routed, not transparent. The "show firewall" command can also be used to determine the firewall operation mode: ciscoasa# show firewall Firewall mode: Transparent SCCP Inspection Denial of Service Vulnerability +---------------------------------------------- A denial of service vulnerability affects the SCCP inspection feature of Cisco ASA 5500 Series Adaptive Security Appliances. Administrators can determine if SCCP inspection is enabled by issuing the "show service-policy | include skinny" command and confirming that output, such as what is displayed in the following example, is returned. ciscoasa# show service-policy | include skinny Inspect: skinny, packet 0, drop 0, reset-drop 0 Alternatively, a device that has SCCP inspection enabled has a configuration similar to the following: class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect skinny ... ! service-policy global_policy global Note: The service policy could also be applied to a specific interface instead of globally, which is displayed in the previous example. SCCP inspection is enabled by default. The following example displays an affected configuration (Cisco ASA Software version 8.0 and 8.1): router rip ... ! phone-proxy <instance name> media-termination address <IP address> ... <Rest of phone proxy feature configuration> Or (Cisco ASA Software version 8.2 and later): router rip ... ! media-termination <instance name> address <IP address> ! <Rest of phone proxy feature configuration> A security appliance is vulnerable if it is processing RIP messages ("router rip") and if a global media termination address is configured for the Cisco Phone Proxy feature (refer to previous example). Note that Cisco ASA Software versions 8.0 and 8.1 only allow a global media termination address. However, in Cisco ASA Software version 8.2 and later, it is possible to tie a media termination address to an interface. This configuration, which is accomplished by issuing the command "address <IP address> interface <interface name>" in media termination configuration mode, is not affected. Neither RIP nor the Cisco Phone Proxy feature is enabled by default. An affected configuration consists of the following minimum commands: crypto ca trustpoint <trustpoint name> keypair <keypair name> crl configure crypto ca server crypto ca certificate chain <trustpoint name> certificate ca 01 ... ! http server enable The local CA server is not enabled by default. Because Cisco PIX 500 Series Security Appliances reached the end of software maintenance releases milestone on July 28, 2009, no further software releases will be available. For more information, refer to the End of Life announcement at http://www.cisco.com/en/US/prod/collateral/vpndevc/ps5708/ps5709/ps2030/end_of_life_notice_cisco_pix_525_sec_app.html. How to Determine Software Versions +--------------------------------- 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 8.3(1): ASA#show version | include Version Cisco Adaptive Security Appliance Software Version 8.3(1) Device Manager Version 6.3(1) Customers who use Cisco Adaptive Security Device Manager (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. It offers firewall, intrusion prevention system (IPS), anti-X, and virtual private network (VPN) services. The number of available packet buffers may decrease when a security appliance receives IPv6 traffic and is not configured for IPv6 operation. IPv6 transit traffic does not cause a problem. Administrators can check packet buffer utilization by issuing the command "show blocks" and inspecting the output for the number of available 1,550-byte blocks. If the number of blocks is zero (indicated by 0 in the CNT column), then the security appliance may be experiencing this issue. For example: ciscoasa# show blocks SIZE MAX LOW CNT 0 400 360 400 4 200 199 199 80 400 358 400 256 1412 1381 1412 1550 6274 0 0 ... This vulnerability is documented in Cisco bug ID CSCtj04707 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0393. Appliances are only vulnerable if SCCP inspection is enabled. Only transit traffic can trigger this vulnerability; traffic that is destined to the appliance will not trigger the vulnerability. This vulnerability is documented in Cisco bug ID CSCtg69457 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0394. Appliances are vulnerable only if both RIP and the Cisco Phone Proxy feature are enabled. Note: the affected configuration requires that a global media termination address is configured, which is the only possible configuration option in Cisco ASA Software versions 8.0 and 8.1. However, it is possible to tie a media termination address to an interface in Cisco ASA Software version 8.2 and later. This configuration is not vulnerable. This vulnerability is documented in Cisco bug ID CSCtg66583 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0395. No authentication is required. This vulnerability is documented in Cisco bug ID CSCtk12352 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0396. 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.

Use-after-free vulnerability in WebCore in WebKit before r77705, as used in Google Chrome before 11.0.672.2 and other products, allows user-assisted remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via vectors that entice a user to resubmit a form, related to improper handling of provisional items by the HistoryController component, aka rdar problem 8938557. WebKit is prone to a denial-of-service vulnerability. WebKit is a set of open source web browser engines jointly developed by companies such as KDE, Apple (Apple), and Google (Google), and is currently used by browsers such as Apple Safari and Google Chrome. A use-after-free vulnerability exists in WebCore in WebKit versions prior to r77705 used in Google Chrome versions prior to 11.0.672.2 and others. The vulnerability is related to improper handling of temporary items by the HistoryController component

The Dell DellSystemLite.Scanner ActiveX control in DellSystemLite.ocx 1.0.0.0 does not properly restrict the values of the WMIAttributesOfInterest property, which allows remote attackers to execute arbitrary WMI Query Language (WQL) statements via a crafted value, as demonstrated by a value that triggers disclosure of information about installed software. The DellSystemLite.Scanner ActiveX control is prone to a directory-traversal vulnerability and an information-disclosure vulnerability because the application fails to sufficiently sanitize user-supplied input. Exploiting these issues may allow an attacker to obtain sensitive information. DellSystemLite.ocx 1.0.0.0 is vulnerable; other versions may also be affected. Dell The DellSystemLite.Scanner control is a scanner control. ---------------------------------------------------------------------- Get a tax break on purchases of Secunia Solutions!

Directory traversal vulnerability in the GetData method in the Dell DellSystemLite.Scanner ActiveX control in DellSystemLite.ocx 1.0.0.0 allows remote attackers to read arbitrary files via directory traversal sequences in the fileID parameter. The DellSystemLite.Scanner ActiveX control is prone to a directory-traversal vulnerability and an information-disclosure vulnerability because the application fails to sufficiently sanitize user-supplied input. Exploiting these issues may allow an attacker to obtain sensitive information. DellSystemLite.ocx 1.0.0.0 is vulnerable; other versions may also be affected. Dell The DellSystemLite.Scanner control is a scanner control. ---------------------------------------------------------------------- Get a tax break on purchases of Secunia Solutions!

The Management Console (webagent.exe) in Cisco Security Agent 5.1, 5.2, and 6.0 before 6.0.2.145 allows remote attackers to create arbitrary files and execute arbitrary code via unspecified parameters in a crafted st_upload request. Authentication is not required to exploit this vulnerability. The flaw exists within the webagent.exe component which is handed requests by an Apache instance that listens by default on TCP port 443. When handling an st_upload request the process does not properly validate POST parameters used for a file creation. The contents of this newly created file are controllable via another POST variable. Successful exploits will allow attackers to modify agent policies and system configuration and perform other administrative tasks, resulting in the complete compromise of an affected device. Failed exploit attempts will result in a denial-of-service condition. This issue is tracked by Cisco Bug ID CSCtj51216. Malicious attackers can exploit these to exploit vulnerable systems. Cisco has released free software updates that address this vulnerability. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110216-csa.shtml.
