Google Researcher Releases iOS Exploit—Could Enable iOS 11 Jailbreak

iOS 11 jailbreak exploit

As promised last week, Google’s Project Zero researcher Ian Beer right now publicly disclosed an exploit which works on almost all 64-bit Apple devices running iOS 11.1.2 or earlier, which can be used to build an iOS jailbreak, allowing users to run apps via non-Apple sources.

On Monday morning, Beer shared the details on the exploit, dubbed “tfp0,” which leveraged double-free memory corruption vulnerabilities inside kernel, the core of the operating system.

Here, “tfp0” stands for “task for pid 0” or the kernel task port—which gives users full control over the core of the operating system.

The Project Zero researcher responsibly reported these vulnerabilities to Apple in October, which were patched by the company with the Discharge of iOS 11.2 on 2nd December.

While Beer says he has successfully tested his proof of concept exploit on the iPhone 6s in addition to also also 7, in addition to also also iPod Touch 6G, he believes which his exploit should work on all 64-bit Apple devices.

Another security researcher confirmed which the exploit released by Beer also works on his Apple TvOS 11.x in addition to also also TV 4K running iOS 11.1.2.

What’s worse? Since Apple’s iOS mobile operating system in addition to also also macOS desktop operating system share the same code base, the kernel for macOS can be also vulnerable to the bug, according to a report published by Project Zero on Google’s Chromium Blog.

Beer said he has also successfully tested the vulnerability on macOS 10.13, running on a MacBook Air 5.2, which Apple patched in macOS 10.13.1.

Earlier versions of the operating systems are still vulnerable to the exploit, which basically grants complete core access to the operating system in addition to also also which can be actually what the jailbreak community requires.

Although we have not heard any news about iOS jailbreaks via the jailbreak community via very long, Beer’s exploit could be the basis for a future iOS 11 jailbreak, allowing iPhone in addition to also also iPad users to install third-party OS customizations via apps which are restricted by Apple.

If iOS 11.1.2 jailbreak surfaces in upcoming days, you can still downgrade to iOS 11.1.2 using iTunes even if you have updated to iOS 11.2 because Apple can be still signing the operating system.
