If there is no way to manipulate the used HTTP_SERVER_VARS there is no way to include something. For sure not via $include_location. Let's take a look at the PHP-Manual: <http://www.php.net/manual/en/reserved.variables.php> * DOCUMENT_ROOT The document root directory under which the current script is executing, as defined in the server's configuration file. I guess if an attacker can manipulate the server's configuration file you have much more to worry about as a remote file inclusion. :-) * PHP_SELF The filename of the currently executing script, relative to the document root. * SCRIPT_FILENAME The absolute pathname of the currently executing script. If one of them can be manipulated from remote, than that may be a vulnerability in PHP or the webserver, but not in the PHP-scripts. So there is no vulnerability. Regards Carsten -- Dipl.-Inform.
