A memory corruption vulnerability in the Internet Explorer scripting engine affects Microsoft Windows 7 SP1, Windows Server 2008 and 2008 R2 SP1, Windows 8.1, Windows RT 8.1, Windows Server 2012 and 2012 R2, Windows 10 Gold/1511/1607/1703/1709, and Windows Server 2016. According to the provided description, the issue arises from how Internet Explorer handles objects in memory. A remote attacker can trigger the flaw via specially crafted web content, causing memory corruption in the browser process and enabling code execution in the security context of the current user.

This repository contains a multi-stage exploit chain targeting CVE-2017-11907, a heap overflow vulnerability in jscript.dll on Windows. The structure includes: - A Visual Studio C++ project (OxidResolver) implementing a DCOM/RPC server that, when triggered, impersonates a client and launches a process (cmd.exe) as SYSTEM, enabling privilege escalation. - A malicious PAC file (wpad.dat) designed to be served via WPAD on a local network. This file contains obfuscated JScript code that exploits the heap overflow in jscript.dll when processed by Internet Explorer. - A JScript proof-of-concept (PoC_for_IE.js) that demonstrates the heap overflow exploit. - Readme files referencing the vulnerability and providing context. The exploit works by luring a Windows 10 machine to use a malicious WPAD server, causing Internet Explorer to process the PAC file and trigger the heap overflow. The overflow allows remote code execution, which is then used to interact with the OxidResolver binary to escalate privileges to SYSTEM. The attack chain leverages network, browser, and local vectors, and is operational with real payloads for both code execution and privilege escalation.
