When I go on the page it says that `Only the Admin can see the flag` `And you aren't the admin`
Lets's take a look at network requests, localstorage, cookies itd. as in standard web challenge.
It looks like there are tow cookies
I changed the first cookie value to 1 The second cookie is a md5 hash which states `anonymous` So I calculated md5 of `admin` and the hash is `21232f297a57a5a743894a0e4a801fc3` After refreshing the page I am an admin.
