A remote code execution vulnerability exists in ZZ Inc. KeyMouse Windows versions 3.08 and prior due to the application's failure to authenticate update requests. An attacker can exploit this by triggering an update process on a vulnerable installation, allowing execution of arbitrary code.

This repository provides a working proof-of-concept exploit for CVE-2022-24644, a remote code execution vulnerability in ZZ Inc. KeyMouse 3.08 for Windows. The exploit leverages the application's insecure update mechanism, which fetches update information and binaries from www.keymouse.com over HTTP without authentication or signature verification. The attacker sets up a malicious HTTP server (cve-2022-24644_poc.py) that mimics the legitimate update server, serving a crafted versions.txt and a malicious executable (proof.exe, compiled from proof.c). The README details the steps: the target's hosts file or DNS must be manipulated to redirect www.keymouse.com to the attacker's server. When the KeyMouse application checks for updates, it downloads and executes proof.exe as Administrator, resulting in a command shell being opened at high integrity. The repository contains three files: a README with exploitation instructions, a Python HTTP server script, and a C source file for the payload. The exploit is operational and demonstrates real code execution on the target.
