How to exploit Joomla 1.5.x
Posted 03 December 2008 - 10:18 AM
1. Getting to the admin Control Panel
2. Uploading shell
3. Messing... =)
We will call the website 'xxxxx.com' for the purposes of this website.
-First we must find a vulnerable host. All versions of Joomla! are vulnerable until next release, but there is a way you can prevent this attack. We will google dork around for a vulnerable website.
Google d0rk ----> intext:"Welcome to the Frontpage"
Now, we choose: xxxxx.com
To test if it is vulnerable we put this at the end of the url:
enter the character:
as the token. If all went well you should be redirected to a page where you can change the admin password. Now go back to xxxxx.com and add:
to the end of the url. Try and login with admin (the default) as the user and the changed pass. I f it didn't work, it means you have the wrong username. This could become a very big guessing game =). I would suggest visiting the forums and looking for the admin username.
Finally! We are on the admin Control Panel of xxxxx.com! Time to upload shell...
Now click on the
icon.Then click on the
tab. Now scroll to the bottom of the page and disable
Check mime types
and add php as a legal file extension. Now get your php shell, I will use locus7s (a variant of c99) as my shell. You can get these shells anywhere. Save it as a php file on your disk. Now go back to the main Control Panel and go to the
and browse your shell from your computer press upload and wait for it to finish. When it says
you may proceed to the messing section =)...
Now go back to xxxxx.com and add
/images/yourshell.php (replace yourshell.php by the name of the shell you uploaded. I would recommend giving your shell a secret name, otherwise people will re-access your shell.)
Now you should be on the shell interface. This might look kind of messed up when you are a beginner, but don't worry...
Click on the folder icon that says
Now go to
and press the
or the button on the far right above the text box. Now you may edit the front page =). Don't forget to press the
Last but not least, go back to the main shell interface and click the
button and now go to
and click on
Now clear the bottom part with your IP and click
Now you're clear to leave =).

I run a Joomla site myself. And decided to test this out. My version is [Joomla! 1.5.6 Production/Stable [ Vusani ] 12-August-2008 22:00 GMT]
Putting index.php?option=com_user&view=reset&layout=confirm at the end of my URL gives me a screen asking me to confirm the token. Entering ' does not send me to a change password screen. It just flicks back to the same 'enter token' screen.
So either your method doesnt work or i have a newer version, which either way i am glad for! Haha.
One question is why do you need to upload the shell? If you have the admin username and password, you can change anything you want anyway via the articles and the main menu/home? Or would this be a backdoor as such... if the owner ends up changing the admin password?
One thing i find interesting in security flaws in Online software like this... is most users aren't that technical. And it's hard to upgrade to a latest version. You can't just log in to the console and press 'update'. You have to do a whole reinstall in most cases, that freaks people out. And not only that, why will the user know they are vulnerable unless they visit sp0it sites? (or they find their frontpage changed.. haha)

I believe all 1.5 versions prior to 1.5.6 are vulnerable.
My version is [Joomla! 1.5.6 Production/Stable [ Vusani ] 12-August-2008 22:00 GMT]
After uploading the php shell, you could do alot more things than just changing the contents of your Joomla site. Like running a bnc, or iroffer or maybe getting root on the box
One question is why do you need to upload the shell?
The System admins do/should know if a web app that they host has some vulnerabilites, so it should be their job to upgrade. But as we can see not all of them do that
why will the user know they are vulnerable unless
The tutorial is just an expansion of
A decent attempt.
1 . Go to url : target.com/index.php?option=com_user&view=reset&layout=confirm
2. Write into field "token" char ' and Click OK.
3. Write new password for admin
4. Go to url : target.com/administrator/
5. Login admin with new password

Also one thing that might be mentioned is as admin you can also enable FTP access through the control panel. You could then FTP in as admin and upload whatever you want... your shell for example, no need to do it via Media if you don't want to.

Expand the article or just put it into an ordered list and save us the time.
