Cisco AnyConnect Secure Mobility Client Arbitrary Code Execution Vulnerability

A vulnerability in the inter-process communication (IPC) channel of Cisco AnyConnect Secure Mobility Client could allow an authenticated, local attacker to execute arbitrary code.

The vulnerability is due to a lack of input sanitization of certain IPC commands. An attacker could exploit this vulnerability by sending crafted messages over the IPC channel. A successful exploit could allow the attacker to write to arbitrary user space memory. This could allow an attacker to execute arbitrary code, disclose information, or crash the AnyConnect application.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.

To exploit this vulnerability, an attacker must authenticate and have local access to the system. These requirements may reduce the likelihood of a successful exploit.

Cisco indicates through the CVSS score that proof-of-concept code exists; however, the code is not known to be publicly available.
