CVE-2026-33293 Details
Description
WWBN AVideo is an open source video platform. Prior to version 26.0, the `deleteDump` parameter in `plugin/CloneSite/cloneServer.json.php` is passed directly to `unlink()` without any path sanitization. An attacker with valid clone credentials can use path traversal sequences (e.g., `../../`) to delete arbitrary files on the server, including critical application files such as `configuration.php`, causing complete denial of service or enabling further attacks by removing security-critical files. Version 26.0 fixes the issue.
A path traversal vulnerability has been identified in WWBN AVideo versions prior to 26.0, specifically within the CloneSite plugin. The issue arises in the 'deleteDump' parameter of 'plugin/CloneSite/cloneServer.json.php', where user input is directly passed to the 'unlink()' function without proper path sanitization. This flaw allows attackers with valid clone credentials to manipulate the file path by using traversal sequences to delete arbitrary files on the server. Critical application files, such as 'configuration.php', can be targeted, leading to a complete denial of service or facilitating further attacks by removing essential security files.
Users are advised to update to AVideo version 26.0 or later, where this vulnerability has been patched. The fix involves adding proper path validation to the 'deleteDump' parameter, ensuring that only files within the designated 'clonesDir' directory can be deleted.
