CVE-2023-32330

Server takeover via improper certificate validation

Published Feb 7, 2024 · Updated Nov 3, 2025

Improper certificate validation in IBM Security Verify Access 10.0.0.0 through 10.0.6.1 allows attackers to take control from adjacent networks. IBM identifies insecure calls as the affected locus but does not disclose which call accepts an untrusted certificate or endpoint. No credentials or user interaction are required, but exploitation requires an adjacent network position and high-complexity conditions; success compromises the server.
