Cisco Unified Communications Manager Remote Blind SQL Injection Vulnerability

Cisco Unified Communication Manager (Unified CM) contains a vulnerability that could allow an unauthenticated, remote attacker to execute a blind Structured Query Language (SQL) injection.

The vulnerability is due to improper validation of user-supplied requests by the Cisco Unified CM. An attacker could exploit this vulnerability by injecting SQL commands. An exploit could allow the attacker to leverage metadata to recreate encrypted information within the database. This metadata could be used to reconstruct encrypted credentials.

Proof-of-concept code that demonstrates an exploit of this vulnerability is publicly available.

Cisco has confirmed the vulnerability in a security advisory and has released a temporary fix.

To exploit this vulnerability, an attacker may require access to trusted, internal networks to send crafted requests to the affected software. This access requirement could limit the likelihood of a successful exploit.

Cisco Unified CM version 8.0 reached the End of Software Maintenance on October 23, 2012. Customers using Cisco Unified CM 8.0(x) versions should contact their Cisco support team for assistance in upgrading to a supported version of Cisco Unified CM.

Cisco Unified CM is the only product confirmed to be vulnerable. Additional voice products may be affected by one or more of the individual vulnerabilities that are described in the advisory. The following products are being investigated but have not yet been confirmed as vulnerable:

Cisco Emergency Responder

Cisco Unified Contact Center Express

Cisco Unified Customer Voice Portal

Cisco Unified Presence Server/Cisco IM and Presence Service

Cisco Unity Connection

This vulnerability can be exploited over the default management ports, TCP port 8080 or 8443.
