Vulnerability Title
WWBN/AVideo has an incomplete fix for a directory traversal bypass via query string in ReceiveImage downloadURL parameters
Source: CVE Program / CVE List V5
Vulnerability Description
WWBN AVideo is an open source video platform. In versions 29.0 and below, the directory traversal fix introduced in commit 2375eb5e0 for `objects/aVideoEncoderReceiveImage.json.php` only checks the URL path component (via `parse_url($url, PHP_URL_PATH)`) for `..` sequences. However, the downstream function `try_get_contents_from_local()` in `objects/functionsFile.php` uses `explode('/videos/', $url)` on the **full URL string** including the query string. An attacker can place the `/videos/../../` traversal payload in the query string to bypass the security check and read arbitrary files from the server filesystem. Commit bd11c16ec894698e54e2cdae25026c61ad1ed441 contains an updated fix.
