Cisco Unified Communications Manager contains a vulnerability that could allow an authenticated, remote attacker to execute arbitrary commands on a targeted device. Updates are not available.
A vulnerability in Cisco Unified Communications Manager (Unified CM) could allow an authenticated, remote attacker to execute commands on the underlying operating system with the privileges of the database user.
The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by submitting malicious input to the affected function.
Proof-of-concept code that demonstrates an exploit of this vulnerability is publicly available.
Cisco has confirmed the vulnerability in a security advisory; however, software updates are not available.
Cisco Unified CM versions 9.1(2) and prior are affected.
To exploit this vulnerability, an attacker requires authenticated access to the targeted system. Authenticated access may require the attacker to access trusted, internal networks. These access requirements 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
An authenticated, remote attacker could exploit the vulnerability to execute arbitrary commands with the privileges of the database user, which could allow the attacker to launch additional attacks.
The vulnerability is due to improper validation of user-supplied input by the affected software.
An authenticated, remote attacker could exploit the vulnerability by submitting crafted input to the affected function on a targeted device. When the malicious input is processed by the underlying operating system on the device, the attacker could execute arbitrary commands with the privileges on the database user, which could allow the attacker to launch additional attacks.
Administrators are advised to contact the vendor regarding future updates and releases.
The security vulnerability applies to the following combinations of products.
Cisco Unified Communications Manager
