CVE-2022-4978 affects Remote Control Server 3.1.1.12 maintained by Steppschuh. The product exposes a custom UDP-based control protocol that accepts remote keyboard input events. When authentication is disabled—which is stated to be the default configuration—the server does not verify the sender before processing these input events. An attacker on the same network can send a crafted sequence of keystroke commands to the server, use those simulated keystrokes to open a system shell, and then execute arbitrary commands on the target host. This results in unauthenticated remote code execution via the exposed remote input/control functionality.

This repository contains a single Metasploit module (remote_control_collection_rce.rb) that exploits an unauthenticated remote code execution vulnerability (CVE-2022-4978) in the Remote Control Server component of the Remote Control Collection by Steppschuh. The exploit targets Windows systems running the vulnerable server (tested on version 3.1.1.12) with default (no password) configuration. The module communicates with the server over UDP port 1926, simulating keyboard input to open a command prompt and execute commands. It starts an HTTP server to host a payload (default: windows/shell/reverse_tcp), instructs the target to download the payload using certutil.exe, and then executes it, providing the attacker with a reverse shell. The exploit leaves artifacts on disk and may cause screen effects. The code is operational and customizable within the Metasploit framework.
