Cisco CallManager 3.2 and earlier, 3.3 before 3.3(5)SR1, 4.0 before 4.0(2a)SR2c, and 4.1 before 4.1(3)SR2 allow remote attackers to (1) cause a denial of service (CPU and memory consumption) via a large number of open TCP connections to port 2000 and (2) cause a denial of service (fill the Windows Service Manager communication queue) via a large number of TCP connections to port 2001, 2002, or 7727.

Security readout for executives and security teams

This vulnerability affects older Cisco CallManager systems and can let a remote attacker disrupt call-management availability by opening many TCP connections. The business impact is service degradation or outage for voice communications, especially if the affected ports are reachable from untrusted networks. Exposure is most likely in legacy Cisco CallManager deployments that still run the listed versions and allow access to TCP ports 2000, 2001, 2002, or 7727 from broad internal, partner, or internet-reachable networks. Treat this as a legacy voice-availability risk. Prioritize remediation where CallManager supports business-critical telephony or has broad network exposure. It is not KEV-listed, but outages can still be operationally significant. Mitigation focus: Upgrade affected Cisco CallManager versions to the fixed releases named in the Cisco advisory.; Review Cisco’s advisory for any version-specific workaround or operational guidance.; Restrict access to the affected TCP ports to trusted voice-management networks only..
