Drupal Captcha Bypass Vulnerability

Vulnerability Assessment Summary
Tries to bypass captcha when registering as a new user in Drupal

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
one third-party module that adds a 'captcha' to various forms such as
for user registration but which can be bypassed using a specially-
crafted 'edit[captcha_response]' parameter. As a result, a possible hacker
can script access to whatever forms the module is designed to protect
from automated abuse.
