WWBN AVideo is an open source video platform. In versions up to and including 26.0, multiple vulnerabilities in AVideo's CloneSite plugin chain together to allow a completely unauthenticated attacker to achieve remote code execution. The `clones.json.php` endpoint exposes clone secret keys without authentication, which can be used to trigger a full database dump via `cloneServer.json.php`. The dump contains admin password hashes stored as MD5, which are trivially crackable. With admin access, the attacker exploits an OS command injection in the rsync command construction in `cloneClient.json.php` to execute arbitrary system commands. Commit c85d076375fab095a14170df7ddb27058134d38c contains a patch.
