Cisco Unified Service Monitor and Cisco Unified Operations Manager are products from the Cisco Unified Communications Management Suite. They provides a way to continuously monitor active calls supported by the Cisco Unified Communications System.
Two vulnerabilities exist in Cisco Unified Service Monitor and Cisco Unified Operations Manager software that could allow an unauthenticated, remote attacker to execute arbitrary code on affected servers. These vulnerabilities can be triggered by sending a series of crafted packets to the affected server over TCP port 9002.
Both of these vulnerabilities are documented in Cisco bug ID CSCtn42961 ( registered customers only) and have been assigned CVE ID CVE-2011-2738.

In installations of Cisco Unified Service Monitor or Cisco Unified Operations Manager where these applications are running on the same system, as the DMF Broker, the administrator can change the following registry key as a workaround:
Change the Args parameter of of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Cisco\Resource Manager\CurrentVersion\Daemons\DfmBroker from --output --port=9002 to --output --port=9002 --accept=127.0.0.1,<hostname>
Note: <hostname> is the hostname of the Cisco Unified Service Monitor and Cisco Unified Operations Manager system. Restart the Daemon Manager after updating the registry.
Mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link: http://www.cisco.com/warp/public/707/cisco-amb-201100914-cusm-lms.shtml
