What the vulnerability does

01Description

A vulnerability in the log subscription subsystem of the Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. The vulnerability is due to insufficient validation of user-supplied input on the web and command-line interface.

A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.
