Zero-day vulnerability in macOS Mojave bypasses system-level privacy permissions

According to security researchers, Apple 's macOS Mojave distributed to users all over the world on Monday contains an implementation of security protection that may expose personal data.

As highlighted by Digita Security's Patrick Wardle, this unique flaw allows unprivileged applications to bypass system level permissions and remove user information from specific applications. Wardle found several security issues related to Apple. Recently, there was leakage of confidential data by the Adware Doctor application.

At the Worldwide Developers Conference held last June, Apple introduced a MacOS security feature that explicitly permits the use of specific applications and hardware. Specifically, you need to be able to access it when camera, microphone, messaging, message, Safari, Time Machine, iTunes backup, location, routine, and system cookie are available. 39, macOS Mojave is running.

Uploaded with short video On TwitterWardle has demonstrated to bypass at least one of these protections.

A simple demo shows the first failed attempt to access and copy the contact via Terminal, which is the result expected as part of Apple 's security measures. After that, Wardle runs an unprivileged application (called "breakMojave") and finds and accesses the Mac address book.

With secure access, Wardle can execute list commands and display all files in private folders, including metadata and images.

To talk to TechCrunchWardle states that this exploit is not a "universal solution" of extended access authorization features, but the possibility to exploit this procedure to access protected data when the user logs in macOS There was a point. As you can see, this flaw is rarely a major problem for most users, but in some circumstances it may be embarrassing.

Security researchers have kept secret details of bugs to protect the public, but said they would turn bypass and pay attention to Apple's shortage. Bug bonus on Mac. Certainly, Wardle's script submits a report to "bugbounty@apple.com. ERROR: MacOS Bug Bonus Program was not found: /"

Apple is currently running the iOS bug program that started in 2016. It provides up to $ 200,000 for bugs related to bootable firmware components even when there are no bugs. The incentive initiative for Mac has not yet begun.

With the current bug …
