CVE-2005-3667

NVD-CWE-OtherPublished: November 18, 2005· Updated: Jun 16, 2026

5.0
CVSS v3.1

Official Description

Multiple unspecified vulnerabilities in multiple unspecified implementations of Internet Key Exchange version 1 (IKEv1) have multiple unspecified attack vectors and impacts related to denial of service, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of information in the original sources, it is likely that this candidate will be REJECTed once it is known which implementations are actually vulnerable. In addition, since "denial of service" is an impact and not a vulnerability, it is unknown which underlying vulnerabilities are actually covered by this particular candidate.

Technical Analysis

CVE-2005-3667 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
