This repository contains a proof-of-concept (PoC) exploit for CVE-2022-30136, a vulnerability in the Windows Network File System (NFS) service (specifically NFS 4.1) that allows for a denial of service (BSOD) via a pool overflow. The main exploit code is in 'CVE-2022-30136.py', a Python script that crafts and sends a series of NFSv4.1 COMPOUND REQUEST packets to a specified target IP and port (default 2049). The exploit demonstrates the vulnerability by causing a crash in the NFS service, but does not achieve remote code execution. The README provides a detailed technical analysis of the vulnerability, the patch, and the exploit development process. The repository is structured with a single exploit script, a README with technical background and usage instructions, and a license file. The exploit is intended for research and demonstration purposes on vulnerable Windows Server systems.
