Cisco said an attacker does not have to be authenticated to exploit the flaw. The flaw affects Cisco UCM versions 4.2, 4.3, 5.1 and 6.0 and Cisco Unfied CallManager versions 3.3, 4.0, 4.1 and 5.0. An update is available to fix the flaw.

A possible workaround could be implemented by disabling the CTL Provider service when not in use. Filtering traffic to the affected systems on screening devices can also mitigate the threat, Cisco said.

There are no known active exploits in the wild, Cisco said.
