WebGUI Authentication Bypass Allows Remote CLI Execution on NEC UNIVERGE IX‑R/IX‑V

An authentication bypass vulnerability exists in the WebGUI of Series UNIVERGE IX-R/IX-V. A user could bypass authentication and execute arbitrary CLI commands by tampering with WebGUI messages and sending them to the device via internet.

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.

Command Injection vulnerability in NEC Corporation UNIVERGE IX from Ver9.2 to Ver10.10.21, for Ver10.8 up to Ver10.8.27, for Ver10.9 up to Ver10.9.14 and UNIVERGE IX-R/IX-V Ver1.2.15 and earlier allows a attacker to inject an arbitrary CLI commands to be executed on the device via the management interface.
