macOS Bug Lets Local Admin Unlock App Store System Prefs With Any Password | #Apple #CyberSecurity #NobodyIsPerfect #Awareness | Apple, Mac, MacOS, iOS4, iPad, iPhone and (in)security... | Scoop.it

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. This means that if your account is an admin and you leave the computer unattended, anyone can change the App Store settings on the Mac without your knowledge.

While this is not as serious as the recent bug that allowed you to gain macOS root access by entering no password repeatedly, it does show that there are some serious code auditing issues in macOS regarding how passwords can be used. This is twice now in as little as three months that the password field was able to be used in macOS to gain extra privileges.


As shown in the video above, using this bug is really simple. Just open up the App Store system preferences and if the little padlock icon is locked, click on it. macOS will then prompt you for a username and password. Enter any username and password you want and press Unlock and the App Store system preferences will become unlocked. This allows you to change settings such as what updates to install, whether to install security updates, and more.
