Authenticated code execution via unrestricted PHP upload
Published Aug 20, 2026 · Updated Aug 25, 2026
Unrestricted file upload in Frauscher Diagnostic System FDS 102 2.8.0 through 2.13.3 allows remote authenticated users to execute code. The upload handler accepts PHP files without adequate file-type validation and stores them under the web-accessible /uploads path, where direct requests invoke the PHP interpreter. High-privileged application access is required; successful execution compromises the FDS web server and can expose, alter, or interrupt the underlying system.
