Apple Releases MacOS High Sierra Security Fix For Critical Root Danger


Apple today released Security Update 2017-001 to fix a severe vulnerability that enables access to the root superuser account with a blank password on any Mac running macOS High Sierra version 10.13.1.

The critical bug came to the limelight after it was tweeted by developer Lemi Ergin yesterday, this bug lets anyone gain administrator privileges by merely entering the username "root" and a blank password in System Preferences > Users & Groups.

The security update is now available in the Mac App Store now, which needs to be installed by all users using macOS High Sierra as soon as possible. Regardless, if the user updates his device, Apple said the security update would be automatically installed on all Macs running macOS High Sierra 10.13.1.

Apple has since apologized for the vulnerability in a statement issued to MacRumors:

Security is a top priority for every Apple product, and regrettably, we stumbled with this release of macOS.

When our security engineers became aware of the issue Tuesday afternoon, we immediately began working on an update that closes the security hole. This morning, as of 8 a.m., the update is available for download, and starting later today it will be automatically installed on all systems running the latest version (10.13.1) of macOS High Sierra.

We greatly regret this error and we apologize to all Mac users, both for releasing with this vulnerability and for the concern it has caused. Our customers deserve better. We are auditing our development processes to help prevent this from happening again.

The vulnerability does not affect macOS Sierra or any other previous version of the operating system.
