Synopsis

The remote Cisco TelePresence Conductor device is affected by a command injection vulnerability.

Description

According to its self-reported version number, remote Cisco TelePresence Conductor device is affected by a command injection vulnerability in GNU Bash known as Shellshock. The vulnerability is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system.
