New security vulnerability on all high sierra OS that allows anyone to gain root access to the computer. If you are prompted to login for something, example could be logging into your computer or to disable your firewall, all that you have to do is change the username to "root" and leave the password blank and hit enter two or three times and it passes the login and your set. Crazy flaw that needs to be patched immediately!!!
