Lab setup is the same as previously mentioned in my last tutorial. Also the methodology is the same.
Limitation in last tutorial of bash bug : In that demonstration I was managed to exploit bash successfully, somehow I could not make sure from client side(my end) that exploitation has gone successful or not. For that I went to vulnerable VM machine and went to that particular directory and checked that the files has been created successfully or not.
Advantage of this technique : In this technique I am making a new header with a variable, in which I will give arbitiary comamnds in order to exploit in the victim''s box. On top of that the result of that command's output will be reflected back at my burp sute's response. So this is the smartness of this payload that we do not need to go to server's end in order to confirm that has our exploitation been successful or not. We can do this by sitting at client side only since the output will be reflected to us.
