Updating macOS can bring back the nasty "root" security bug

Updating macOS can bring back the nasty

Apple quickly posted a Terminal-based fix to its support pages before reissuing the security patch with a permanent solution a few hours later. Reportedly, users who had "not yet upgraded their operating system from the original version of High Sierra 10.13.0, to the most recent version 10.13.1, but had downloaded the patch, say the "root" bug reappears when they install the most recent macOS system update".

Numerous users have confirmed to Wired that Apple's hastily rolled out bug fix is far from flawless itself.

A day after a researcher discovered a huge login security flaw in the latest version of Apple's macOS High Sierra operating system, the company said that it would review its software development process.

This has been an incredibly terrible week for Apple's operating systems.

Forbes writer Thomas Fox-Brewster wrote yesterday that the bug "may go down as one of the most embarrassing vulnerabilities in Apple history".

It is noted that remotely realize the vulnerability impossible - the attacker must still have direct access to your device. Furthermore, for those installing again after updating to macOS 10.13.1, Apple doesn't say that a reboot is required. As a temporary measure Apple recommends to activate the root user and set the password manually.

Tests of the flaw indicated that it could be used to alter a user's system settings that normally require a chosen username and password.

You'd think that would be the end of Apple's software troubles for this week, but you'd be wrong.

"Oh my god that should not work but it does", another user responded yesterday on the forum. "Some bug in authentication is ENABLING root with no password the first time it fails!"

The serious and surprising root security bug in macOS High Sierra is back for some users, shortly after Apple declared it fixed.

In the case of a fix for this latest vulnerability, "I would imagine [Apple] will be pushing it out as a high priority", Cluley said. "It seemed like the issue had been revealed, but Apple had not noticed yet".
