Arbitrary file read via path prefix bypass
Published Jan 10, 2024 · Updated Nov 4, 2025
Path traversal in WWBN AVideo 11.6 and dev commit 15fed957fb allows remote authenticated users to read arbitrary server files. The isValidURLOrPath check accepts paths beginning with /var/www/ without ensuring the resolved path remains beneath an allowed directory, and decideMoveUploadedToVideos copies the selected file into the web-accessible videos directory. Video-upload permission is required; the demonstrated path exposes non-PHP files readable by the web service account.
