4 Steps Hacking Jcow Social Networking Web Server via Arbitrary Code Execution


 4 Steps Hacking Jcow Social Networking Web Server via Arbitrary Code Execution

After very long times I didn't write about hacking webserver, today "again" when surfing around I've found that Jcow Social netwoking engine can be exploited and the exploit ranking marked as "excellent".
So actually what happen when you have this Jcow vulnerable version??The simple thing is the attacker can go through your web server directory and doing everything there. For example if you hosting your Jcow vulnerable version(on unsecure hosting also :-) ) you can own your web server directory.
In this example, let's say I have a Jcow vulnerable web server in IP address 192.168.8.94. Actually it's better to try installing your own web server, but if you want to find out Jcow in the wild you can search through Google dork "intext:Powered by Jcow 4.2.0" and register as normal user there. In this tutorial I have already register as username : victim and password also victim :-)
Okay I hope you understand what I say above :-P to make it more realistic, let's try the tutorial…

Level : Medium

Victim Server : work fine if victime use Windows XP SP3
Victim vulnerable application : JCow 4.2
Attacker O.S : obiously you need Backtrack 5 R1

Requirement :

Here only you need bellow two item.
Which is your actual need.

1#. Metasploit framework

2.# Jcow.rb exploit mediafire.com

Now lets start this article.

4 Steps Hacking Jcow Social Networking Web Server via Arbitrary Code Execution Process:

1.# first of all you simly  Copy the 

downloaded jcow.rb exploit from the 

download link above and copy it into /pentest/exploits/framework/modules/exploits/remote/ folder(for example see the command below).
cp jcow.rb /pentest/exploits/framework/modules/exploits/remote/
now you see the text "framework" in blue color it's only because I'm using 

Backtrack 5 R1 and using metasploit 

v4.0.1, so the name was depends on 

your Metasploit version, maybe on your 

computer it can be "framework3" or 

"framework2" so on..so dont have

confused.

2.# now when you copy successfully 

after that,simply  Open your Metasploit 

console and then use the exploit you just added before see bellow 


msf > use exploit/remote/jcow


3.# now when you complete step 2 , The 

next step we need to view the available 

switch for this exploit by running show 

options command, and then configured it(see the text with red color).

msf  exploit(jcow) > set rhost 192.168.8.94 --> set the target IP
rhost => 192.168.8.94
msf exploit(jcow) > set username victim --> set the username
username => victim
msf exploit(jcow) > set password victim --> set the password
password => victim
msf exploit(jcow) > set uri jcow --> only if jcow not in/directory fill it here
uri => jcow
Importent:::?

Set uri can be used if jcow was not 

installed on webserver main directory

for example http://web-server.com/jcow.

4#. now your work has been almost  

done ,After everything was set up 

successfully, the next thing to do was 

exploiting or running the exploit by using

  exploit command.
