The following flaw was found in Symfony, a PHP framework for web projects: Applications with ESI or SSI support enabled, that use the FragmentListener, are vulnerable to unauthorized access. A malicious user can call any controller via the /_fragment path by providing an invalid hash in the URL (or removing it), bypassing URL signing and security rules. FragmentListener throws an AccessDeniedHttpException in case URL is not signed correctly. However, the ExceptionListener triggers kernel events again by making a sub-request. Since the FragmentListener does no signing for sub-requests, the controller is called even though the original request was forbidden. As a result the user receives a 403 response with content generated by the controller. This issue is fixed in Symfony 2.3.29, 2.5.12, and 2.6.8.
