CVE-2022-32761Public exploitNetwork attack vector

Authenticated file read via unrestricted image URL

Published Aug 22, 2022 · Updated Apr 15, 2025

Arbitrary file read in WWBN AVideo 11.6 and dev master commit 3f7c0364 allows remote authenticated users to read host files via HTTP. The objects/aVideoEncoderReceiveImage.json.php handler passes the user-controlled downloadURL_image value through url_get_contents to PHP file_get_contents without restricting it to remote URLs, then stores the content at a web-accessible JPG path. The requester needs video-upload permission and must own the referenced video; successful access exposes any file readable by the web service, including configuration files containing database credentials.
