Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP application that is affected by a
security bypass vulnerability.

Description :

The version of Drupal installed on the remote host includes at least

can script access to whatever forms the module is designed to protect
from automated abuse.
