## Description
This module exploits a UAF vulnerability in WebKit's JavaScriptCore library, CVE-2016-4657.
## Vulnerable Application
The exploit should work on 32-bit or 64-bit devices running iOS 9.3.4 or earlier, though it has been tested so far on 64-bit devices running 9.3.1.
## Verification Steps
* Start msfconsole
* `use exploit/apple_ios/browser/webkit_trident`
* `set LHOST` and `SRVHOST` as appropriate
* exploit
* Browse to the given URL with a vulnerable device from Safari
* Note that the payload is specially created for this exploit, due to sandbox
limitations that prevent spawning new processes.
## Scenarios
### 64bit (ME279NF/A) running iOS 9.3.1:
