CVE-2003-1115: The Session Initiation Protocol (SIP) implementation in Nortel Networks Succession Communication Server 200...

The Session Initiation Protocol (SIP) implementation in Nortel Networks Succession Communication Server 2000, when using SIP-T, allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted INVITE messages, as demonstrated by the OUSPG PROTOS c07-sip test suite.

Security readout for executives and security teams

A legacy Nortel SIP server could be crashed, and possibly compromised, by malformed SIP INVITE traffic when SIP-T is used. For organizations still operating this platform, the main business risk is disruption of voice or telecom services. The source bundle does not confirm active exploitation or a specific vendor fix. Exposure is most likely in organizations still running Nortel Networks Succession Communication Server 2000 with SIP-T enabled, especially where SIP signaling is reachable from untrusted networks or carrier interconnects. Treat as high priority only if the named legacy Nortel SIP platform is still in use. The issue can affect telecom availability, but evidence is old and incomplete. Mitigation focus: Identify any Nortel Succession Communication Server 2000 deployments.; Confirm whether SIP-T is enabled or externally reachable.; Check vendor or maintainer guidance for fixes or supported migration paths..
