This repository contains a proof-of-concept (POC) exploit for CVE-2021-43224, a vulnerability in the Windows Common Log File System (CLFS) driver. The main code file, 'poc.cpp', is a C++ program that uses the CLFS API to create or open a log file at a specific path, registers a manageable log client, and queries log file information. This sequence of operations triggers a denial of service (BSOD) on vulnerable Windows systems. The exploit is local and requires execution on the target machine. The repository includes Visual Studio project files for building the POC, a README describing the exploit and its effects, and a single code file implementing the exploit logic. No remote or network endpoints are involved; the attack vector is purely local, targeting the CLFS driver via crafted file operations.
