Memory leak in the Call Telephony Integration (CTI) Framework authentication for Cisco CallManager 3.0 and 3.1 before 3.1(3) allows remote attackers to cause a denial of service (crash and reload) via a series of authentication failures, e.g. via incorrect passwords.

Security readout for executives and security teams

This is an old Cisco CallManager denial-of-service issue. Repeated failed CTI authentication attempts can leak resources until the service crashes and reloads. The source bundle does not show data theft, code execution, or confirmed active exploitation. Exposure is limited to organizations still running Cisco CallManager 3.0 or 3.1 before 3.1(3), especially where CTI authentication is reachable by untrusted users or networks. Treat as a legacy availability risk. It matters most if old CallManager systems still support business telephony or contact-center workflows. Prioritize inventory and upgrade or isolation over emergency response unless matching exposure exists. Mitigation focus: Identify any Cisco CallManager 3.0 or 3.1 deployments.; Upgrade affected systems to Cisco's fixed release guidance, including 3.1(3) or later.; If upgrade is delayed, restrict CTI access to trusted networks where feasible..
