Summary

A vulnerability in the command-line interface (CLI) of the Cisco Prime 
Collaboration server could allow an authenticated, local attacker to access

The vulnerability is due to insufficient sanitization of user-supplied input.
An attacker could exploit this vulnerability by bypassing policy restrictions
and executing commands on the underlying operating system. The user needs to 
log in to the device with valid administrator-level credentials.
