CVE-2005-4466 describes a heap-based buffer overflow in the SIPParser function of i3sipmsg.dll within Interaction SIP Proxy versions prior to 3.0.011. This vulnerability allows unauthenticated remote attackers to cause a denial of service and potentially execute arbitrary code by sending a specially crafted REGISTER request containing excessive space or tab characters in the SPI version number. With a CVSS score of 7.5, it is considered highly severe due to its network-based attack vector, low attack complexity, and potential for partial confidentiality, integrity, and availability impact. While not listed on CISA's KEV catalog and showing no active exploitation or significant community discussion, an ExploitDB entry (EDB-26922) exists, indicating public exploit code for a denial-of-service attack.
