Authenticated file disclosure via URL path traversal
Published Jan 10, 2024 · Updated Nov 4, 2025
Path traversal in WWBN AVideo dev master commit 15fed957fb allows remote authenticated users to read arbitrary server files. The aVideoEncoderReceiveImage.json.php handler accepts downloadURL_image, discards the URL prefix before /videos/, and passes the traversal-derived path to file_get_contents. Video-upload permission is required; retrieved bytes are stored as an image that the user can fetch, exposing files such as configuration.php and its cryptographic salt.
