For this tutorial you need :
Mozilla Firefox
Live HTTP Headers -> https://addons.mozilla.org/en-US/firefox…p-headers/
Find an website which allows you to upload .jpg , .png or any other extension
So now once you have found a website , we are going to try and upload .php file
For example if i try to upload inj3ct0r.php
The server rejects the file and says wrong extension
Now we are going to rename our shell to
inj3ct0r.php.jpg
Now try opening the Image , Right click on it and open in new tab
Now go to the upload spot and click browse
Go to the Live Http Headers and run it
The Capture Box should be checked
Now upload the shell , Wait for it to load completely and our inj3ct0r.php.jpg should come up on the Live Http Headers
Highlight the shell name and click on the replay button
A new windows should popup , now we have to find our shell name for example inj3ct0r.php.jpg and rename is to inj3ct0r.php
Now when you have done that click the replay button again
The page should refresh
Now right click on the picture you upload and open in new Tab
There you go the shell should be there
