## Description

A vulnerability in Cisco BroadWorks could allow an authenticated, local attacker to elevate privileges to the root user on an affected device. The vulnerability is due to insufficient input validation by the operating system CLI. An attacker could exploit this vulnerability by issuing a crafted command to the affected system. A successful exploit could allow the attacker to execute commands as the root user. To exploit this vulnerability, an attacker must have valid BroadWorks administrative privileges on the affected device.
