According to its self-reported version number, the detected Drupal application is affected by a vulnerability in Symfony library X-Original-URL and X-Rewrite-URL HTTP headers support.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Web application components can sometimes rely on request HTTP headers like 'X-Original-URL' or 'X-Rewrite-URL' to override the original path of this request. Attackers can leverage this vulnerability to conduct further attacks in order to bypass restrictions or conduct cache poisonning attacks.

Multiple vulnerabilities were discovered in the Symfony PHP framework which could lead to cache bypass, authentication bypass, information disclosure, open redirect, cross-site request forgery, deletion of arbitrary files, or arbitrary code execution.

Several security vulnerabilities have been discovered in symfony, a PHP web application framework. Numerous symfony components are affected: Security, bundle readers, session handling, SecurityBundle, HttpFoundation, Form, and Security\Http.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its self-reported version, the instance of Drupal running on the remote web server is 8.x prior to 8.5.6. It is, therefore, affected by a restriction bypass vulnerability in the embedded Symfony library.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
