Off-by-one error in the Certificate Trust List (CTL) Provider service (CTLProvider.exe) in Cisco Unified Communications Manager (CUCM, formerly CallManager) before 20070711 allow remote attackers to execute arbitrary code via a crafted packet that triggers a heap-based buffer overflow.

Security readout for executives and security teams

This flaw affects Cisco Unified Communications Manager, formerly CallManager. A malformed network packet to the CTL Provider service could trigger memory corruption and allow remote code execution. The bundle does not include CVSS scoring or proof of active exploitation, but the business impact is serious because CUCM supports enterprise voice communications. Exposure is likely limited to organizations running legacy Cisco Unified Communications Manager or CallManager deployments predating the 20070711 Cisco advisory. Internet exposure is not established in the bundle; assess internal voice, management, and service network reachability. Prioritize this for any still-running legacy CUCM environment. Remote code execution against voice infrastructure can disrupt communications and create a foothold. If no legacy CUCM exists, priority drops to confirmation and documentation. Mitigation focus: Review Cisco advisory cisco-sa-20070711-cucm for affected and fixed releases.; Inventory CUCM or CallManager systems and record exact versions.; Upgrade affected systems according to Cisco guidance..
