CVE-2019-0752 is a remote code execution vulnerability in the Internet Explorer scripting engine caused by improper handling of objects in memory. The flaw is described as a scripting engine memory corruption issue in which crafted web content can trigger unsafe memory operations while Internet Explorer processes scriptable objects. Successful exploitation can corrupt process memory and allow attacker-controlled code to execute in the context of the browser process.

This repository contains a proof-of-concept (PoC) exploit for CVE-2019-0752, a write-what-where vulnerability in Internet Explorer 11's scripting engine on Windows 10 x64 (32-bit IE). The exploit is implemented in a single HTML file (exploit.html) that combines JavaScript and VBScript to manipulate DOM elements and memory structures. The exploit achieves arbitrary read/write in memory, locates KERNEL32.dll, resolves the address of WinExec, and hijacks a vtable to execute arbitrary commands. The payload is not hardcoded and does not use external scripts like PowerShell, making it stealthier. The only fingerprintable endpoint is the string '\..\splwow64', used internally in the exploit's memory manipulation. The README provides context and references the original ZDI blog post. The exploit is a functional PoC and demonstrates code execution, but does not include a weaponized or easily customizable payload.
