PROBLEM
While investigating Mr. Green for something completely unrelated, we found this login page. Maybe you can find a way in?
SOLUTION
It's a login form and if you are good in CTFs the first thing that might hit you is the SQLi but it's not it is just a login page.
Try admin
for both username and password
