CVE-2005-4466: Heap-based buffer overflow in the SIPParser function in i3sipmsg.dll in Interaction SIP Proxy before 3.0.01...

Heap-based buffer overflow in the SIPParser function in i3sipmsg.dll in Interaction SIP Proxy before 3.0.011 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a REGISTER request with a SPI version number that contains a large number of space or tab characters.

Security readout for executives and security teams

This is an old remote memory corruption flaw in Interaction SIP Proxy before 3.0.011. A malformed SIP REGISTER request can crash the service and may allow arbitrary code execution. Business urgency depends on whether any legacy Interaction SIP Proxy instance is still deployed and reachable. Exposure is most likely in legacy voice or contact-center environments running Interaction SIP Proxy earlier than 3.0.011, especially where SIP traffic can reach the proxy from untrusted networks. Treat this as a legacy exposure hunt, not a broad emergency. If the product is present and reachable, prioritize remediation because remote denial of service is documented and code execution is possible. Mitigation focus: Identify any Interaction SIP Proxy deployments and their versions.; Upgrade vulnerable instances to 3.0.011 or later where vendor-supported.; Restrict SIP access to trusted peers and network segments..
