Cisco Unified Communications Manager Denial of Service Vulnerability

A vulnerability in the Tomcat service throttling mechanism of the Cisco Unified Communications Manager could allow an authenticated, remote attacker to cause a denial of service (DoS) condition.

The vulnerability is due to sending multiple authenticated requests to Cisco Unified Communications Manager. An attacker could exploit this vulnerability by causing the Cisco Unified Communications Manager Management page to become slow or unresponsive.

Cisco has confirmed the vulnerability; however, software updates are not available.

To exploit this vulnerability, an attacker must authenticate to the targeted device. This access requirement may reduce the likelihood of a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
