Natas 4

http://natas4.natas.labs.overthewire.org/

This one says:

Access disallowed. You are visiting from "" while authorized users should come only from "http://natas5.natas.labs.overthewire.org/" 

It's likely using the comically misspelled "HTTP Referer" header to figure out where you came from.

What happens if we intercept the request to http://natas4.natas.labs.overthewire.org/ with BURP proxy, add an "HTTP Referer" header, and set it to "http://natas5.natas.labs.overthewire.org/"?


Success!
