Multiple Vulnerabilities in Cisco Unified Communications Manager
Advisory ID: cisco-sa-20130717-cucm
Revision 1.0
For Public Release 2013 July 17 16:00 UTC (GMT)
+---------------------------------------------------------------------
Summary
=======
Cisco Unified Communications Manager (Unified CM) contains multiple vulnerabilities that could be used together to
allow an unauthenticated, remote attacker to gather user credentials, escalate privileges, and execute commands to gain
full control of the vulnerable system. A successful attack could allow an unauthenticated attacker to access, create or
modify information in Cisco Unified CM.
On June 6, 2013, a French security firm, Lexfo, delivered a public presentation on VoIP security that included a
demonstration of multiple vulnerabilities used to compromise Cisco Unified CM. During the presentation, the researchers
demonstrated a multistaged attack that chained a number of vulnerabilities Structured Query Language (SQL) resulted in
a complete compromise of the Cisco Unified CM server. The attack chain used the following types of vulnerabilities:
Blind Structured Query Language (SQL) injection
Command injection
Privilege escalation
Cisco PSIRT greatly appreciates the opportunity to work with researchers on security vulnerabilities and welcomes the
opportunity to review and assist in product reports.
Cisco has released a Cisco Options Package (COP) file that addresses three of the vulnerabilities documented in this
advisory. Cisco is currently investigating the remaining vulnerabilities. Workarounds that mitigate these
vulnerabilities are not available.
