Detailsinfo

A vulnerability was found in WWBN AVideo up to 25.x and classified as critical. Affected by this issue is an unknown code of the file view/hls.php of the component HLS Streaming Endpoint. The manipulation of the argument videoDirectory with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality. CVE summarizes:

WWBN AVideo is an open source video platform. Prior to version 26.0, the HLS streaming endpoint (`view/hls.php`) is vulnerable to a path traversal attack that allows an unauthenticated attacker to stream any private or paid video on the platform. The `videoDirectory` GET parameter is used in two divergent code paths — one for authorization (which truncates at the first `/` segment) and one for file access (which preserves `..` traversal sequences) — creating a split-oracle condition where authorization is checked against one video while content is served from another. Version 26.0 contains a fix for the issue.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-33292 since 03/18/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. 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:view/hls.php it is possible to find vulnerable targets with Google Hacking.

Upgrading to version 26.0 eliminates this vulnerability.
