Description
Joomla Extension - ordasoft.com - Unauthenticated Remote Code Execution in OrdaSoft Joomla CCK < 8.3.16 - site/uploader.php is reached through the component’s normal frontend routing (task=getContent), a task with no authentication or ACL check anywhere in the dispatch chain. The handler validates the uploaded file’s content with a real magic-byte MIME check, but the extension allow-list that would otherwise restrict the saved file’s extension was present in the source and commented out. The saved file’s extension was taken directly from the attacker-supplied filename with no validation, and the file was written to a path directly under the Joomla web root that is executed by the PHP handler. An image/PHP polyglot, a file whose header bytes satisfy the MIME check with PHP source appended after, passed the content check while carrying a .php extension of the attacker’s choosing.
