Safari Webkit JIT Exploit for iOS 7.1.2

Description

This module exploits a JIT optimization bug in Safari Webkit. This allows us to write shellcode to an RWX memory section in JavaScriptCore and execute it. The shellcode contains a kernel exploit (CVE-2016-4669) that obtains kernel rw, obtains root and disables code signing. Finally we download and execute the meterpreter payload. This module has been tested against iOS 7.1.2 on an iPhone 4.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
