SOLUTION
As you can see that the hint takes you to HTTP cookie wiki page that means it has to do something with cookies. So Just open the developers tool in your browser and reload the page and then in storage section of the developer tools you'll see a cookie with name user which is set to unknown.
Okay we have the cookie now but how will this be helpful? well if you noticed that as you visit the given link it written I am gROOT see that capitalization on ROOT that means this will give acess to ROOT so just change the user: unknown in the cookie we found to user: ROOT and reload the page.
