Detailsinfo

A vulnerability was found in WWBN AVideo up to 25.x. It has been classified as critical. Affected is the function glob of the file listFiles.json.php of the component POST Parameter Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. CVE summarizes:

WWBN AVideo is an open source video platform. Prior to version 26.0, the `listFiles.json.php` endpoint accepts a `path` POST parameter and passes it directly to `glob()` without restricting the path to an allowed base directory. An authenticated uploader can traverse the entire server filesystem by supplying arbitrary absolute paths, enumerating `.mp4` filenames and their full absolute filesystem paths wherever they exist on the server — including locations outside the web root, such as private or premium media directories. Version 26.0 contains a patch for the issue.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-33238 since 03/18/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

By approaching the search of inurl:listFiles.json.php it is possible to find vulnerable targets with Google Hacking.

Upgrading to version 26.0 eliminates this vulnerability. Applying the patch 870cf24a7632d4f1a5d5549b59103c18f39e3a21 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
