Unauthenticated version disclosure via HTTP response headers
Published Jan 7, 2022 · Updated Sep 16, 2024
Information disclosure in IBM Security Verify Access 10.0.0, 10.0.1.0, and 10.0.2.0 allows remote attackers to read version data via HTTP headers. The public advisory does not identify the header name or emitting code path; it confirms that HTTP responses expose sensitive product version information. No authentication or user interaction is required, and the disclosed data supports product fingerprinting and planning of further attacks.
