There seems to be a major flaw in Apple’s macOS High Sierra operating system that allows anyone to log into a machine and gain system administrator access without so much as entering a password. The vulnerability has been publicly disclosed on Twitter; it’s not clear whether the problem was privately reported to Apple ahead of time, which is the encouraged practice when security vulnerabilities are uncovered. (The company maintains an invite-only bug bounty program.) Despite its incredibly alarming simplicity, The Verge is not reproducing the steps here.
However, The Verge has been able to confirm the major security issue remains present as of MacOS 10.13.1, the current release of High Sierra. When the problem is exploited, the user is authenticated into a “System Administrator” account and is given full ability to view files and even reset or change passwords for pre-existing users on that machine. Apple ID email addresses can be removed and altered, as well.
The level of unbridled access this security hole permits — and it abruptly being made public — will almost certainly prompt Apple to move fast in releasing a critical update for its Mac operating system.
