CVE-2026-14952Network attack vector

Sensitive file disclosure via unauthenticated HTTP endpoints

Published Aug 20, 2026 · Updated Aug 20, 2026

Missing authentication in Frauscher Diagnostic System FDS 102 2.1.0 through 2.13.3 allows remote attackers to read sensitive files over HTTP. The FDS Web server serves /FdsBackup.zip and files under /downloads/* without checking for a valid session. Network access to the web interface is sufficient, exposing detailed railway signaling and track-layout information without reported write or service-interruption impact.
