CVE-2018-4441 is a memory corruption vulnerability affecting multiple Apple products, including iOS, tvOS, watchOS, Safari, iTunes for Windows, and iCloud for Windows. The vulnerability is due to improper memory handling, which could allow an attacker to corrupt memory and potentially execute arbitrary code or cause a denial of service. The issue was addressed by Apple with improved memory handling in the affected products.

This repository is a proof-of-concept (PoC) exploit for CVE-2018-4441, targeting the PlayStation 4's WebKit engine on firmware 6.20. The exploit is delivered as a set of JavaScript files and an HTML page (index.html) intended to be hosted on a web server and accessed via the PS4's browser. The main exploit logic is in wkexploit.js, which establishes arbitrary read/write primitives and leaks object addresses by exploiting a bug in JavaScriptCore's array handling. Once these primitives are established, index.html sets up a ROP (Return-Oriented Programming) framework (rop.js) to execute code in the context of the browser process. The syscalls.js file provides a mapping of system calls for post-exploit actions. The exploit demonstrates its capabilities by running syscalls such as sys_getpid and sys_getuid, showing code execution in userland. The exploit does not provide a full jailbreak or kernel exploit, but is a significant step toward further exploitation. The repository is well-structured, with each file serving a clear purpose in the exploit chain. No hardcoded network endpoints or IP addresses are present; the main fingerprintable endpoints are the file paths themselves, which must be hosted and accessed by the target PS4.
