Vulnerability from variot

Unspecified vulnerability in the RTSP inspection feature on the Cisco Application Control Engine (ACE) Module with software before A2(3.2) for Catalyst 6500 series switches and 7600 series routers, and the Cisco Application Control Engine (ACE) 4710 appliance with software before A3(2.6), allows remote attackers to cause a denial of service (device reload) via crafted RTSP packets over TCP, aka Bug IDs CSCta85227 and CSCtg14858. The Cisco Application Control Engine Application Control Engine is a solution for a portfolio of load balancing and application delivery products. RTSP is used for RealAudio, RealNetworks, Apple QuickTime 4, RealPlayer and Cisco IP/TV links. RTSP applications use TCP and UDP port 554 as control channels. Modules and applications only support RTSP over TCP. Devices that only enable RTSP detection are affected by this vulnerability. RTSP detection is not enabled by default. Note: To exploit this vulnerability, you need to complete a three-way handshake. Only Transit communication can trigger this vulnerability, and the target communication for the affected device is not affected by this vulnerability. An attacker can exploit this issue to cause an affected device to crash and reload, denying service to legitimate users. This issue is tracked by Cisco bug IDs CSCta85227 and CSCtg14858. Workarounds that mitigate some of the vulnerabilities are available.

Note: These vulnerabilities are independent of each other. For specific version information, refer to the Software Versions and Fixes section of this advisory.

Note: This vulnerability is independent from the other RSTP and SIP inspection vulnerabilities described in this advisory. SIP inspection is disabled by default. All rights reserved.

Products Confirmed Not Vulnerable +--------------------------------

The Cisco ACE XML Gateway, the Cisco ACE Web Application Firewall, and the Cisco ACE GSS 4400 Series Global Site Selector Appliances are not affected by any of the vulnerabilities that are described in this advisory.

No other Cisco products are currently known to be affected by these vulnerabilities. Multiple vulnerabilities exist in both products. These vulnerabilities are independent of each other. The following information provides the details about each of the vulnerabilities that are addressed in this advisory. Deep packet inspection is a special case of application inspection where the ACE examines the application payload of a packet or a traffic stream and makes decisions based on the content of the data. During HTTP deep inspection, the main focus of the application inspection process is on HTTP attributes such as the HTTP header, the URL, and to a limited extent, the payload. User-defined regular expressions can also be used to detect "signatures" in the payload.

SIP Inspection DoS Vulnerability ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

SIP is used for call handling sessions, especially two-party conferences. SIP inspection is disabled by default.

Note: TCP or UDP SIP packets may cause a device reload. 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:

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 software table (below) describes the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. Administrators can disable RTSP inspection by issuing the "no inspect rtsp" command under the respective policy map.

Note: This workaround is only feasible if RTSP inspection is not needed or required in a load-balancing deployment.

    "data": "Unspecified vulnerability in the RTSP inspection feature on the Cisco Application Control Engine (ACE) Module with software before A2(3.2) for Catalyst 6500 series switches and 7600 series routers, and the Cisco Application Control Engine (ACE) 4710 appliance with software before A3(2.6), allows remote attackers to cause a denial of service (device reload) via crafted RTSP packets over TCP, aka Bug IDs CSCta85227 and CSCtg14858. The Cisco Application Control Engine Application Control Engine is a solution for a portfolio of load balancing and application delivery products. RTSP is used for RealAudio, RealNetworks, Apple QuickTime 4, RealPlayer and Cisco IP/TV links. RTSP applications use TCP and UDP port 554 as control channels. Modules and applications only support RTSP over TCP. Devices that only enable RTSP detection are affected by this vulnerability. RTSP detection is not enabled by default. Note: To exploit this vulnerability, you need to complete a three-way handshake. Only Transit communication can trigger this vulnerability, and the target communication for the affected device is not affected by this vulnerability. \nAn attacker can exploit this issue to cause an affected device to crash and reload, denying service to legitimate users. \nThis issue is tracked by Cisco  bug IDs CSCta85227 and CSCtg14858. \nWorkarounds that mitigate some of the vulnerabilities are available. \n\nNote: These vulnerabilities are independent of each other. For\nspecific version information, refer to the Software Versions and\nFixes section of this advisory. \n\nNote: This vulnerability is independent from the other RSTP and SIP\ninspection vulnerabilities described in this advisory. SIP inspection is disabled by default.

Multiple\nvulnerabilities exist in both products. These vulnerabilities are\nindependent of each other. The following information\nprovides the details about each of the vulnerabilities that are\naddressed in this advisory. Deep packet inspection is a special case of application\ninspection where the ACE examines the application payload of a packet\nor a traffic stream and makes decisions based on the content of the\ndata. During HTTP deep inspection, the main focus of the application\ninspection process is on HTTP attributes such as the HTTP header, the\nURL, and to a limited extent, the payload. User-defined regular\nexpressions can also be used to detect \"signatures\" in the payload. \n\nSIP Inspection DoS Vulnerability\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nSIP is used for call handling sessions, especially two-party\nconferences. SIP inspection is disabled by default. \n\nNote: TCP or UDP SIP packets may cause a device reload. The CVSS\nscoring in this Security Advisory is done in accordance with CVSS\nversion 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\nCSCta85227, CSCtg14858 - RTSP Inspection DoS Vulnerability\n\nCVSS Base Score - 7.8\n\nAccess Vector           - Network\nAccess Complexity       - Low\nAuthentication          - None\nConfidentiality Impact  - None\nIntegrity Impact        - None\nAvailability Impact     - Complete\n\nCVSS Temporal Score - 6.4\n\nExploitability          - Functional\nRemediation Level       - Official-Fix\nReport Confidence       - Confirmed\n\nCSCtb54493 - HTTP, RTSP, and SIP Inspection DoS Vulnerability\n\nCVSS Base Score - 7.8\n\nAccess Vector           - Network\nAccess Complexity       - Low\nAuthentication          - None\nConfidentiality Impact  - None\nIntegrity Impact        - None\nAvailability Impact     - Complete\n\nCVSS Temporal Score - 6.4\n\nExploitability          - Functional\nRemediation Level       - Official-Fix\nReport Confidence       - Confirmed\n\nCSCta20756 - SSL DoS Vulnerability\n\nCVSS Base Score - 7.8\n\nAccess Vector           - Network\nAccess Complexity       - Low\nAuthentication          - None\nConfidentiality Impact  - None\nIntegrity Impact        - None\nAvailability Impact     - Complete\n\nCVSS Temporal Score - 6.4\n\nExploitability          - Functional\nRemediation Level       - Official-Fix\nReport Confidence       - Confirmed\n\nCSCta65603, CSCta71569 - SIP Inspection DoS Vulnerability\n\nCVSS Base Score - 7.8\n\nAccess Vector           - Network\nAccess Complexity       - Low\nAuthentication          - None\nConfidentiality Impact  - None\nIntegrity Impact        - None\nAvailability Impact     - Complete\n\nCVSS Temporal Score - 6.4\n\nExploitability          - Functional\nRemediation Level       - Official-Fix\nReport Confidence       - Confirmed\n\nImpact\n======\n\nSuccessful exploitation of any of the vulnerabilities described in\nthis security advisory may cause a reload of the affected device. \nRepeated exploitation could result in a sustained DoS condition. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult:\n\nhttp://www.cisco.com/go/psirt\n\nand any subsequent advisories to determine exposure and a\ncomplete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. \n\nEach row of the software table (below) describes the earliest\npossible releases that contain the fix (along with the anticipated\ndate of availability for each, if applicable) are listed in the\n\"First Fixed Release\" column of the table. The \"Recommended Release\"\ncolumn indicates the releases which have fixes for all the published\nvulnerabilities at the time of this Advisory. A device running a\nrelease in the given train that is earlier than the release in a\nspecific column (less than the First Fixed Release) is known to be\nvulnerable. Cisco recommends upgrading to a release equal to or later\nthan the release in the \"Recommended Releases\" column of the table. \nAdministrators can disable RTSP inspection by issuing the \"no inspect\nrtsp\" command under the respective policy map. \n\nNote: This workaround is only feasible if RTSP inspection is not\nneeded or required in a load-balancing deployment. \n\nHTTP, RTSP, and SIP Inspection DoS Vulnerability\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nThis vulnerability can be mitigated by disabling HTTP, RTSP, and SIP\ninspection if they are not required. \n\nAdministrators can disable HTTP inspection by issuing the \"no inspect\nhttp\" command under the respective policy map. \n\nAdministrators can disable RTSP inspection by issuing the \"no inspect\nrtsp\" command under the respective policy map. \n\nAdministrators can disable SIP inspection by issuing the \"no inspect\nsip\" command under the respective policy map. \n\nNote: This workaround is only feasible if HTTP, RTSP, and SIP\ninspections are not needed or required in a load-balancing\ndeployment. \n\nSSL DoS Vulnerability\n~~~~~~~~~~~~~~~~~~~~~\n\nThere are no workarounds available to mitigate this vulnerability. \n\nSIP Inspection DoS Vulnerability\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nThis vulnerability can be mitigated by disabling SIP inspection if it\nis not required. SIP inspection is disabled by default. \nAdministrators can disable SIP inspection by issuing the \"no inspect\nsip\" command under the respective policy map. \n\nNote: This workaround is only feasible if SIP inspection is not\nneeded or required in a load-balancing deployment. \n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities. Prior to deploying software, customers should\nconsult their maintenance provider or check the software for feature\nset compatibility and known issues specific to their environment. \n\nCustomers may only install and expect support for the feature sets\nthey have purchased.
