Detailsinfo

A vulnerability, which was classified as critical, was found in WWBN AVideo up to 29.0. Affected is some unknown processing of the component Endpoint. 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. In 29.0 and earlier, an unauthenticated remote attacker can read arbitrary image files anywhere on disk that the PHP user can open — including private user-profile photos that the application's normal serving wrappers gate behind ACLs, admin-uploaded thumbnails, encrypted-video poster frames, and image content under sibling-app directories reachable via .. traversal. The endpoint requires no authentication.
