The Session Initiation Protocol (SIP) implementation in IPTel SIP Express Router 0.8.9 and earlier 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

This issue affects legacy IPTel SIP Express Router versions 0.8.9 and earlier. A remote party could send malformed SIP INVITE messages that may crash the service and, according to the CVE description, could possibly allow arbitrary code execution. The business risk is highest where this old SIP router is still reachable from untrusted networks. Exposure is likely limited to organizations still running IPTel SIP Express Router 0.8.9 or earlier, especially internet-facing SIP signaling infrastructure. The bundle’s affected-product metadata is incomplete, so inventory confirmation is required. Treat as a high-priority legacy exposure check, not a broad emergency. If affected SIP infrastructure is internet-facing or business-critical, prioritize remediation or isolation because the stated impacts include service outage and possible code execution. Mitigation focus: Inventory any IPTel SIP Express Router deployments and confirm exact versions.; Check IPTel and CERT guidance for fixed versions or vendor-recommended remediation.; Restrict SIP access to trusted networks and known peers where operationally possible..
