The clue indicates that we should somehow manipulate the cookie in order to getlogged-in as admin.
So I first browsed around the site to see what cookies get set, but all we getis the same encrypted cookie we can see on other problems. Looks like we haveto forge a new cookie.
It was then a matter of guesswork :
- `username=admin` : Nope.- `user=admin` : Nope.- `admin=True` (similar as the previous "Logon" task) : we get the flag: `picoCTF{n0l0g0n_n0_pr0bl3m_26b0181a}`
