"There is a version of Form Mail Script, a PHP script by Ralf Stadtaus,
installed on the remote host that suffers from a remote file include
vulnerability involving the 'script_root' parameter of the
'inc/formmail.inc.php' script.  By leveraging this flaw, an attacker
may be able to view arbitrary files on the remote host or to execute
arbitrary PHP code, possibly taken from third-party hosts if PHP's
'register_globals' setting is enabled." );
