tag_summary = "According to its version number, the remote version of phpbb
  is prone to an authentication-bypass vulnerability because it fails
  to properly enforce privilege requirements on some operations.

  Attackers can exploit this vulnerability to gain unauthorized access
  to the affected application, which may aid in further attacks.

  Versions prior to phpBB 3.0.4 are vulnerable.";
