SSH Misconfiguration: Missing Authentication
Abstract
目標 SSH 伺服器不要求驗證。
Explanation
任何包含敏感資訊或具有特殊權限的功能的伺服器 (例如遠端管理面板) 都必須要求驗證才能存取。否則,攻擊者只需猜出常見使用者名稱,就可以竊取敏感資訊或控制目標主機。
用戶端可以使用
範例 1:以下 Paramiko 程式碼會嘗試使用「none」驗證要求向伺服器進行驗證。
用戶端可以使用
NoneAuth
驗證方法來確定可用的驗證方法。範例 1:以下 Paramiko 程式碼會嘗試使用「none」驗證要求向伺服器進行驗證。
client = SSHClient()
client.connect(host, port, auth_strategy=NoneAuth("user"))
