Message-id: <20080213.sql@psirt.cisco.com> Date: Wed, 13 Feb 2008 15:20:00 -0000 From: Cisco Systems Product Security Incident Response Team <psirt@...co.com> To: full-disclosure@...ts.grok.org.uk Cc: psirt@...co.com Subject: Cisco Security Advisory: SQL injection in Cisco Unified Communications Manager -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: SQL injection in Cisco Unified Communications Manager Document ID: 100358 Advisory ID: cisco-sa-20080213-cucmsql http://www.cisco.com/warp/public/707/cisco-sa-20080213-cucmsql.shtml Revision 1.0 For Public Release 2008 February 13 1600 UTC (GMT) - --------------------------------------------------------------------- Summary ======= Cisco Unified Communications Manager is vulnerable to a SQL Injection attack in the parameter key of the admin and user interface pages. A successful attack could allow an authenticated attacker to access information such as usernames and password hashes that are stored in the database. Cisco has released free software updates that address this vulnerability. Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-0026 leavingcisco.com has been assigned to this vulnerability. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080213-cucmsql.shtml. Affected Products ================= Vulnerable Products +------------------ Cisco Unified Communication Manager 5.0/5.1 versions prior to 5.1(3a) and 6.0/6.1 versions prior to 6.1(1a) are affected by this vulnerability. The software version of a CallManager or Unified Communications Manager system can be determined by navigating to Show > Software via the administration interface. For Unified Communications Manager, the software version can also be determined by running the show version active command in the Command Line Interface (CLI). Products Confirmed Not Vulnerable +-------------------------------- Cisco CallManager or Unified Communication Manager systems prior to 5.0 are not affected by this vulnerability. No 3.x and 4.x releases are vulnerable. No other Cisco products are known to be affected by this vulnerability. Details ======= Cisco Unified CallManager/Communications Manager (CUCM) is the call processing component of the Cisco IP telephony solution. This solution extends enterprise telephony features and functions to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. An attacker can trigger this SQL injection vulnerability by entering a specially crafted value is entered in the key parameter of either the admin or user interface page. Attacks against this vulnerability are conducted through the web interface and use the http or https protocol. A successful attack could terminate a SQL call and force a connection to the back-end database resulting in the disclosure of potentially sensitive information such as usernames and password hashes. This vulnerability is documented as bug ID CSCsk64286 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 performed 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 CSCsl08519 - SQL Injection Vulnerability in User And Admin Interface Pages CVSS Base Score - 4 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - Partial Integrity Impact - None Availability Impact - None CVSS Temporal Score - 3.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== An authenticated attacker may be able to exploit this vulnerability to extract records from the Cisco Unified Communications Manager database. A successful attack might retrieve sensitive data such as user names, passwords hashes, and information from call records. An attacker cannot use this vulnerability to alter or delete call record information from the database. 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. Version 5.1 - Fixed Release 5.1(3a): http://www.cisco.com/pcgi-bin/tablebuild.pl/callmgr-51?psrtdcat20e2 Version 6.1 - Fixed Release 6.1(1a) http://www.cisco.com/pcgi-bin/tablebuild.pl/callmgr-61?psrtdcat20e2 Workarounds =========== There are no workarounds for this vulnerability. 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/products/prod_warranties_item09186a008088e31f.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@...co.com or security-alert@...co.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@...co.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. Free upgrades for non-contract customers must be requested through the TAC.
