Cisco IOS 12.1YD, 12.2T, 12.3 and 12.3T, when configured for the IOS Telephony Service (ITS), CallManager Express (CME) or Survivable Remote Site Telephony (SRST), allows remote attackers to cause a denial of service (device reboot) via a malformed packet to the SCCP port.

Security readout for executives and security teams

This issue affects Cisco IOS devices running embedded voice call-processing features. A remote malformed SCCP packet can force the device to reboot, disrupting phone services and potentially branch communications. The bundle does not provide CVSS, CWE, or detailed fixed-release information. Exposure is likely limited to Cisco IOS routers configured for ITS, CallManager Express, or SRST with SCCP reachable from untrusted or broad internal networks. Treat as a resilience risk for legacy Cisco voice infrastructure. Prioritize if affected routers support emergency calling, branch telephony, or sites without redundant call processing. Mitigation focus: Review Cisco’s vendor advisory for fixed releases or supported workarounds.; Inventory IOS devices running ITS, CME, or SRST features.; Reduce SCCP reachability to trusted voice-management segments where feasible..
