"According to its self-reported version, Cisco Unity Connection running on the remote host is affected by a
denial of service (DoS) vulnerability. Due to improper API authentication and incomplete verification of the API
request, an unauthenticated, remote attacker can send a specially crafted HTTP request to a specific API causing a
DoS condition due to high CPU utilization. A successful attack can negatively impact user traffic and management.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
