Synopsis

According to its self-reported version number, the version of Cisco TelePresence Video Communication Server is affected by a command injection vulnerability known as Shellshock in its included GNU Bash shell. 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. The API over HTTP(S) and/or SSH can therefore be exploited.
An attacker must be authenticated before the system is exposed to this exploit.
Solution
Upgrade to version 7.2.4 / 8.1.2 / 8.2.2 / 8.5 or later.See Also
