The Internet Key Exchange version 1 (IKEv1) implementation in NEC UNIVERGE IX1000, IX2000, and IX3000 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.

Security readout for executives and security teams

This CVE affects IKEv1 handling in NEC UNIVERGE IX1000, IX2000, and IX3000 devices. A remote attacker could send crafted IKE packets that may crash the device and possibly run arbitrary code. Public details are limited, and severity is not scored. Exposure is most relevant where NEC UNIVERGE IX1000, IX2000, or IX3000 devices accept IKEv1 traffic, especially from untrusted networks. The source bundle does not provide version ranges or CPEs. Treat this as an exposure-driven legacy infrastructure risk. Prioritize review if these NEC VPN devices are internet-facing or still support IKEv1, but avoid assuming active exploitation or a confirmed patch without vendor guidance. Mitigation focus: Identify NEC UNIVERGE IX1000, IX2000, and IX3000 devices in the environment.; Check NEC vendor guidance for affected firmware, fixes, or replacement direction.; Disable IKEv1 where it is not operationally required and vendor-supported..
