Cisco Meeting Server Denial of Service Vulnerability

A vulnerability in Cisco Meeting Server versions prior to 2.2.2 could allow an authenticated, remote attacker to cause the system to reload, resulting in a denial of service (DoS) condition.

The vulnerability is due to video calls being made on systems with a particular configuration. An attacker could exploit this by knowing a valid URI that directs to a Cisco Meeting Server. An attacker could then make a video call and cause the system to reload.

There are no workarounds that address this vulnerability.
