CVE-2019-0539 is a remote code execution vulnerability in Microsoft's Chakra scripting engine used by Microsoft Edge and ChakraCore. According to the provided content, the flaw exists in the way the Chakra scripting engine handles objects in memory, resulting in memory corruption. Microsoft refers to it as the "Chakra Scripting Engine Memory Corruption Vulnerability." Successful exploitation would involve triggering the memory-handling flaw through crafted script content processed by the vulnerable engine.

This repository contains a proof-of-concept exploit for CVE-2019-0539, a vulnerability in Microsoft's ChakraCore JavaScript engine. The repository consists of two files: a minimal README and the main exploit script 'p0c.js'. The exploit script is written in JavaScript and demonstrates advanced exploitation techniques, including the creation of arbitrary read/write primitives, stack pivoting, and the construction of a ROP chain. The script is intended to be run in a vulnerable ChakraCore environment, such as a browser or standalone engine, and is capable of hijacking control flow to achieve code execution. The exploit is a proof-of-concept and does not include a weaponized or fully automated payload, but it provides a solid foundation for further exploitation. No network endpoints or external services are referenced; the exploit operates entirely within the JavaScript engine's memory space.
