CVE-2018-0834 is a memory corruption vulnerability in the scripting engine used by Microsoft Edge and ChakraCore on Windows 10 (Gold, 1511, 1607, 1703, 1709) and Windows Server 2016. The vulnerability arises from improper handling of objects in memory by the scripting engine, which can be triggered by a specially crafted web page. Successful exploitation allows an attacker to execute arbitrary code in the context of the current user.

This repository contains a working exploit for CVE-2018-0834, a vulnerability in Microsoft's ChakraCore JavaScript engine (used in Microsoft Edge). The main exploit logic is in 'a.js', which demonstrates a full browser exploit chain: it achieves arbitrary read/write via a crafted fake object, leaks the base addresses of ChakraCore, ntdll, kernel32, and rpc4 modules, and constructs a ROP chain to bypass modern mitigations (CFG, DEP, ASLR). The exploit culminates in executing 'C:\Windows\SysWOW64\calc.exe' using WinExec, proving arbitrary code execution. The exploit is operational and tailored for a specific vulnerable version of ChakraCore, as evidenced by the use of static offsets and module base calculations. The repository also includes a README.md with a brief description and a message.txt file containing debug output and stack traces from ChakraCore, likely to assist in exploit development or debugging. No network endpoints are present; the attack vector is browser-based, targeting users who visit a malicious web page or open a crafted JavaScript file in a vulnerable environment.
