Drupal 8 before 8.2.8 and 8.3 before 8.3.1 allows critical access bypass by authenticated users if the RESTful Web Services (rest) module is enabled and the site allows PATCH requests.

According to its self-reported version number, the detected Drupal application is affected by an access bypass vulnerability due to an unspecified flaw when the RESTful Web Services (rest) module is enabled and the site allows PATCH requests. An authenticated, remote attacker can exploit this to bypass critical access restrictions.

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

-     [8.3.1](https://www.drupal.org/project/drupal/releases/8     .3.1)

  - [Drupal Core - Critical - Access Bypass -     SA-CORE-2017-002](https://www.drupal.org/SA-CORE-2017-00     2)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
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 8.2.8 or 8.3.x prior to 8.3.1. It is, therefore, affected by an access bypass vulnerability due to an unspecified flaw when the RESTful Web Services (rest) module is enabled and the site allows PATCH requests. An authenticated, remote attacker can exploit this to bypass critical access restrictions.

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