Detailsinfo

A vulnerability was found in WWBN AVideo up to 26.0. It has been declared as critical. Affected by this vulnerability is the function Plugin::getDatabaseFileName of the file objects/pluginRunDatabaseScript.json.php of the component Parameter Handler. The manipulation of the argument name with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginRunDatabaseScript.json.php` endpoint accepts a `name` parameter via POST and passes it to `Plugin::getDatabaseFileName()` without any path traversal sanitization. This allows an authenticated admin (or an attacker via CSRF) to traverse outside the plugin directory and execute the contents of any `install/install.sql` file on the filesystem as raw SQL queries against the application database. Commit 81b591c509835505cb9f298aa1162ac64c4152cb contains a patch.
