An unauthenticated arbitrary file upload vulnerability exists in Tiki Wiki CMS Groupware version 15.1 and earlier via the ELFinder component's default connector (connector.minimal.php), which allows remote attackers to upload and execute malicious PHP scripts in the context of the web server. The vulnerable component does not enforce file type validation, allowing attackers to craft a POST request to upload executable PHP payloads through the ELFinder interface exposed at /vendor_extra/elfinder/.
