RFI (Remote File Inclusion) : Website Hacking TuT

Thnks to owner Minhal Mehdi
Remote File Inclusion (RFI) is a type of vulnerability most often found on websites. It allows an attacker to include a remote file, usually through a script on the web server. The vulnerability occurs due to the use of user-supplied input without proper validation. This can lead to something as minimal as outputting the contents of the file, but depending on the severity, to list a few it can lead to:
Code execution on the web server
Code execution on the client-side such as JavaScript which can lead to other attacks such as cross site scripting (XSS).
Denial of Service (DoS)
Data Theft/Manipulation

Lets Start 
1st Step : Find a Vunerable websites using Google Dork

“inurl:index.php?page=” its Most Popular Dork of RFI hacking

This will show all the pages which has “index.php?page=” in their URL, Now to test whether the website is vulnerable to Remote file Inclusion or not the hacker use the following command

see example of this website

So the hacker url will become

If after executing the command the homepage of the google shows up then then the website is vulnerable to this attack if it does not come up then you should look for a new target. In my case after executing the above command in the address bar Google homepage shows up indicating that the website is vulnerable to this attack.

Now the hacker would upload the shells to gain access. The most common shells used are c99 shell or r57 shell. I would use c99 shell. You can download c99 shell from the link below:

The hacker would first upload the shells to a webhosting site such as,, or another free hosts etc.

Now here is how a hacker would execute the shells to gain access. Lets say that the url of the shell is

Now here is how a hacker would execute the following command to gain access

Don't Forget To  add “?” after .txt at the end of url or else the shell will not execute. Now the hacker is inside the website and he could do anything with it
