apianti Posted November 29, 2017 Share Posted November 29, 2017 Apparently there appears to be a vulnerability where you can authenticate with root user and no password. https://www.reddit.com/r/apple/comments/7g6y06/anyone_can_login_as_root_with_empty_password_on/ https://twitter.com/lemiorhan/status/935578694541770752 https://news.ycombinator.com/item?id=15800676 4 Link to comment https://www.insanelymac.com/forum/topic/330098-macos-high-sierra-root-user-vulnerability/ Share on other sites More sharing options...
Maniac10 Posted November 29, 2017 Share Posted November 29, 2017 Apple always brings the best user experience, this time it's a vulnerability even a 5 year old can exploit. For now as countermeasure just change the root user's password with: passwd root Link to comment https://www.insanelymac.com/forum/topic/330098-macos-high-sierra-root-user-vulnerability/#findComment-2541274 Share on other sites More sharing options...
David-B Posted November 29, 2017 Share Posted November 29, 2017 Has anyone here tried it? I know they say you shouldn't, but it seems harmless as long as you set a root password.

smolderas Posted November 29, 2017 Share Posted November 29, 2017 MacOS came always with root account without password. It was always deactivated though, and one would always activate it explicitly.
