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.
