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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20080213-cucmsql.

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 ( registered customers only) .

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
