Check if you are vulnerable description
Cisco Emergency Responder, Unified Communications Manager, Unified Communications Manager IM and Presence Service, and Unity Connection are listed as affected. The available record does not state what an attacker can achieve or what access is required, so practical exploitability cannot be assessed from this information.
mitigation
Apply Cisco's applicable software-hardening updates for each affected product; the available record does not identify fixed versions. Limit access to affected systems to trusted networks and authorized administrators while identifying the appropriate update.
