There is a workaround for this vulnerability.\r\n\r\nCisco has made free software available to address these\r\nvulnerabilities for affected customers.\r\n\r\nCommon Vulnerabilities and Exposures (CVE) identifier CVE-2008-0027\r\nhas been assigned to this vulnerability.\r\n\r\nThis advisory is posted at \r\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080116-cucmctl.shtml.\r\n\r\nAffected Products\r\n=================\r\n\r\nNote: Cisco Unified CallManager Versions 4.2, 4.3, 5.1 and 6.0 have\r\nbeen renamed as Cisco Unified Communications Manager. CUCM Versions\r\n3.3, 4.0, 4.1 and 5.0 retain the Cisco Unified CallManager name.\r\n\r\nVulnerable Products\r\n+------------------\r\n\r\nThese products are vulnerable:\r\n\r\n * Cisco Unified CallManager 4.0\r\n * Cisco Unified CallManager 4.1 Versions prior to 4.1(3)SR5c\r\n * Cisco Unified Communications Manager 4.2 Versions prior to 4.2(3)\r\n SR3\r\n * Cisco Unified Communications Manager 4.3 Versions prior to 4.3(1)\r\n SR1\r\n\r\nThe version of software running on a CUCM 4.x system can be\r\ndetermined by navigating to Help > About Cisco Unified CallManager\r\nand selecting the Details button via the CUCM Administration\r\ninterface.\r\n\r\nProducts Confirmed Not Vulnerable\r\n+--------------------------------\r\n\r\nCUCM Versions 3.3, 5.0, 5.1, 6.0, 6.1 and Cisco CallManager Express\r\nare not affected by this vulnerability. No other Cisco products are\r\ncurrently known to be affected by this vulnerability.\r\n\r\nDetails\r\n=======\r\n\r\nCisco Unified Communications Manager (CUCM) is the call processing\r\ncomponent of the Cisco IP telephony solution that extends enterprise\r\ntelephony features and functions to packet telephony network devices,\r\nsuch as IP phones, media processing devices, voice-over-IP (VoIP)\r\ngateways, and multimedia applications.\r\n\r\nWhen a CUCM server is deployed in secure mode, a Certificate Trust\r\nList (CTL) is used by Cisco Unified IP Phone devices to verify the\r\nidentity of CUCM servers. The CTL contains public keys and other\r\ninformation to allow the Cisco IP Phone devices to establish a\r\ntrusted relationship with a CUCM server. The CTL is provisioned using\r\nthe CTL Provider service on a CUCM server and with the CTL Provider\r\nclient on an administrator workstation. The CTL Provider service\r\nneeds to be enabled during the initial configuration of a CUCM server\r\n/cluster or when changes are required to the CTL. Please consult the\r\nWorkarounds section of this advisory for information on how to\r\ndetermine if the CTL Provider service is enabled on a CUCM server.\r\n\r\nThe CTL Provider service of the CUCM contains a heap overflow\r\nvulnerability that could allow a remote, unauthenticated user to\r\ncause a DoS condition or execute arbitrary code. The CTL Provider\r\nservice listens on TCP port 2444 by default, but the port can be\r\nmodified by the user. This issue is documented in Cisco Bug ID\r\nCSCsj22605.\r\n\r\nVulnerability Scoring Details\r\n=============================\r\n\r\nCisco has provided scores for the vulnerabilities in this advisory\r\nbased on the Common Vulnerability Scoring System (CVSS). The CVSS\r\nscoring in this Security Advisory is done in accordance with CVSS\r\nVersion 2.0.\r\n\r\nCVSS is a standards-based scoring method that conveys vulnerability\r\nseverity and helps determine urgency and priority of response.\r\n\r\nCisco has provided a base and temporal score. Customers can then\r\ncompute environmental scores to assist in determining the impact of\r\nthe vulnerability in individual networks.\r\n\r\nCisco has provided an FAQ to answer additional questions regarding\r\nCVSS at\r\n\r\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\r\n\r\nCisco has also provided a CVSS calculator to help compute the\r\nenvironmental impact for individual networks at\r\n\r\nhttp://intellishield.cisco.com/security/alertmanager/cvss \r\n\r\nCSCsj22605 - CUCM CTL Provider Heap Overflow Vulnerability\r\n\r\nCVSS Base Score - 10 \r\n\r\n Access Vector - Network\r\n Access Complexity - Low\r\n Authentication - None\r\n Confidentiality Impact - Complete\r\n Integrity Impact - Complete\r\n Availability Impact - Complete\r\n\r\nCVSS Temporal Score - 8.3 \r\n\r\n Exploitability - Functional\r\n Remediation Level - Official-Fix\r\n Report Confidence - Confirmed\r\n\r\nImpact\r\n======\r\n\r\nSuccessful exploitation of this vulnerability may result in a DoS\r\ncondition or the execution of arbitrary code.\r\n\r\nSoftware Versions and Fixes\r\n===========================\r\n\r\nWhen considering software upgrades, also consult \r\nhttp://www.cisco.com/go/psirt and any subsequent advisories to \r\ndetermine exposure and a complete upgrade solution.\r\n\r\nIn all cases, customers should exercise caution to be certain the\r\ndevices to be upgraded contain sufficient memory and that current\r\nhardware and software configurations will continue to be supported\r\nproperly by the new release. If the information is not clear, contact\r\nthe Cisco Technical Assistance Center (TAC) or your contracted\r\nmaintenance provider for assistance.\r\n\r\nWorkarounds\r\n===========\r\n\r\nIt is possible to workaround the vulnerability by disabling the CTL\r\nProvider service when not in use. Access to the CTL Provider service\r\nis required for the initial configuration of the CUCM authentication\r\nand encryption features, or during configuration updates. For the\r\nCUCM 4.x systems, please consult the following documentation for\r\ndetails on how to disable the CUCM services:\r\n\r\nhttp://www.cisco.com/en/US/products/sw/voicesw/ps556/products_administration_guide_chapter09186a008070ec49.html\r\n\r\nFiltering traffic to the affected CUCM systems on screening devices\r\ncan be used as a mitigation technique for this vulnerability. To\r\nmitigate the CTL Producer service overflow, access to TCP port 2444\r\nshould be permitted only between the CUCM servers and administrator\r\nworkstations running the CTL Provider client. There is currently no\r\nsupported method to configure filtering directly on a CUCM system.\r\n\r\nIt is possible to change the default ports of the CTL Provider (TCP\r\nport 2444) service. If changed, filtering should be based on the port\r\nvalue used. The value of the port can be viewed in CUCM\r\nAdministration interface by following the System > Service Parameters\r\nmenu and selecting the CTL Provider service.\r\n\r\nFilters blocking access to TCP port 2444 should be deployed at the\r\nnetwork edge as part of a transit access control list (tACL). Further\r\ninformation about transit access control lists is available in the\r\nwhite paper "Transit Access Control Lists: Filtering at Your Edge,"\r\nwhich is available at the following link:\r\n\r\nhttp://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801afc76.shtml\r\n\r\nAdditional mitigations that can be deployed on Cisco devices within\r\nthe network are available in the Cisco Applied Mitigation Bulletin\r\ncompanion document for this advisory:\r\n\r\nhttp://www.cisco.com/warp/public/707/cisco-amb-20080116-cucmctl.shtml\r\n\r\nObtaining Fixed Software\r\n========================\r\n\r\nCisco has released free software updates that address these\r\nvulnerabilities. Prior to deploying software, customers should\r\nconsult their maintenance provider or check the software for feature\r\nset compatibility and known issues specific to their environment.\r\n\r\nCustomers may only install and expect support for the feature sets\r\nthey have purchased.
