Critical 10.0
In plain English
A critical-severity OS command injection in AVideo from WWBN. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 13.3% (higher than 96% of all known vulnerabilities). Ready-made attack tooling exists: Nuclei.
Official description
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.
