Nginx version disclosure via enabled server tokens
Published Jan 30, 2024 · Updated May 29, 2025
Information disclosure in vantage6 UI before 4.2.0 allows remote attackers to obtain the bundled nginx version from HTTP responses. The Dockerfile leaves nginx server tokens enabled, causing the Server response header and generated error pages to include the nginx release. No authentication or user interaction is required; disclosure is limited to software-version information useful for identifying nginx-specific attack opportunities.
