MacOS High Sierra unlocks App Store Preferences with any password

MacOS High Sierra unlocks App Store Preferences with any password”

A bug has been discovered in macOS 10.13.2 that allows you to unlock the App Store system preferences using any username and password as long as you are logged in as a local admin. The App Store settings are also unlocked by default, meaning the password would only be requested if the user has clicked on the padlock icon to prevent settings being changed.

In November previous year, a serious "root" flaw was discovered in macOS High Sierra that allowed anyone to log into the admin account simply by using the username "root" with a blank password after repeatedly clicking on the login button multiple times.

The impact is small as it's only preferences for one application and, to get to it, you need to log into the operating system - and that password layer seems just fine.

The macOS High Sierra 10.13.2 update improves the stability, compatibility and security of your Mac.

While the discovery of the flaw may be alarming for some Mac users, the potential for it to be exploited in an attack is perhaps limited.

The flaw allows anyone with access to your Mac to enter any password in the App Store section of the System Preferences app which clearly shouldn't happen. If it is unlocked, lock it and then try unlocking it using your username and any password. The flaw follows a series of notable security bugs that shipped in recent weeks including the notorious root access flaw that allowed anyone to access critical account settings and more. That would leave those flaws exploitable on the machine. Apple has reportedly already fixed the bug in beta versions of the next macOS High Sierra update.
