## Overview

A vulnerability in the CLI of multiple Cisco Unified Communications products could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device as the root user.

This vulnerability is due to improper validation of user-supplied command arguments. An attacker could exploit this vulnerability by executing crafted commands on the CLI of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of an affected device as the root user. To exploit this vulnerability, the attacker must have valid administrative credentials.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
