This repository provides a working exploit for CVE-2021-35448, a remote code execution vulnerability in the Remote Mouse (WiFi Mouse) application for Windows. The main script, 'CVE-2021-35448.py', is a Python exploit that connects to the target's TCP port 1978 and sends specially crafted packets to execute arbitrary commands. The exploit supports two main modes: executing a custom command or establishing a reverse shell. For the reverse shell, it serves 'powercat.ps1' via a local HTTP server and instructs the target to download and execute it, which then connects back to the attacker's listener, providing a PowerShell shell. The repository includes the main exploit script, a PowerShell script for reverse shells ('powercat.ps1'), and a README with usage instructions and background. The exploit is operational and can be used for both command execution and interactive shells, provided the target is running the vulnerable application.
