CVE-2017-7117 is a memory corruption vulnerability in the WebKit component used by multiple Apple products, including iOS, Safari, iCloud for Windows, iTunes for Windows, and tvOS, prior to version 11 (or 7.0/12.7 for iCloud/iTunes). The vulnerability can be triggered by a remote attacker through a specially crafted web page, leading to memory corruption and potentially arbitrary code execution or application crash.

This repository contains a proof-of-concept (POC) exploit for CVE-2017-7117, a type confusion and use-after-free vulnerability in JavaScriptCore (JSC) affecting iOS 10.3.4 and earlier, Safari before 11.0, and WebKitGTK 2.16.0. The main exploit is implemented in 'poc.js', which demonstrates how to trigger the vulnerability to leak the memory address of a JavaScript object (addrof primitive). The exploit works by manipulating the JIT compiler's type inference, freeing a large array, and then spraying memory to locate a target object. The README provides detailed background, setup instructions, and explains the exploit's mechanism. The code is a POC and does not provide full arbitrary read/write or code execution, but establishes a crucial primitive for further exploitation. No network or file system endpoints are present; the attack vector is browser-based, requiring execution in a vulnerable JSC environment.
