So I have been assigned the task of getting into this website. The task is to bypass a webserver login block, which gives me the error of "You are not authorized to view this page". The previous assignments have involved looking at the page source code and finding vulnerabilities to exploit, so I am assuming I have to do the same for this one. The professor said it involved cookies.
This is all I really have to go on. He just told us to get into the website by any means.
