适用场景

  • ONTAP 9
  • FSx
  • Cloud Volumes ONTAP (CVO)
  • SMB/CIFS
  • Netlogon (NTLM身份验证)
  • CVE-2022-38023 - Netlogon RPC特权提升漏洞

问题解答

1.为使用NTLMv1或NTLMv2进行域身份验证而配置的ONTAP功能 、例如 CIFS、Vscan、RBAC、域通道等会受到影响

 ::> set advanced ::*> vserver cifs session show -vserver <vserver> -fields auth-mechanism,address,windows-user node vserver session-id connection-id address auth-mechanism windows-user ------------ --------- -------------------- ------------- ------------ -------------- ------------ netapp-01a <vserver> 17134789207261194186 2550496605 10.62.125.88 NTLMv2 DEMO\user6 netapp-01b <vserver> 17134789207261194188 2550496606 10.216.29.42 Kerberos DEMO\Administrator 2 entries were displayed. 

注意:如果Kerberos身份验证尝试失败,则 默认 回退为NTLM (NTLMv1或NTLMv2)。

2.影响:在DC服务器修补程序升级后、使用NTLM的所有CIFS域身份验证都将失败:  RFE 1514175

3.   在 2023年6月13日之前需要执行SU530中规定的操作- 安装Microsoft的CVE-2022-38023修补程序时、将进入"默认强制实施"阶段

 

这些阶段对ONTAP有何影响?

Microsoft阶段

发生了哪些变化

这对ONTAP 9有何影响?

我有哪些选择?

2023年7月-执行阶段

2023年7月11日发布的Windows更新将删除 设置 QuiqureSeal:1的功能

强制将QuiqureSeal设置为  2,将忽略注册表值的内容。

  • 升级到固定版本的 RFE 1514175
  • 确保客户端使用Kerberos身份验证将避免依赖Netlogon/NTLM域身份验证
设置了"RequieSeal":1后的ONTAP影响:
  • 域控制器可能会将以下事件ID 5838记录为 警告
设置了"RequieSeal":2后的ONTAP影响:
FAILURE: Pass-through authentication failed. (NT Status: NT_STATUS_NO_LOGON_SERVERS(0xc000005e))
  • EMS还会在以下事件中指明无可用DC。

secd.netlogon.noServers: None of the Netlogon servers configured for Vserver (vs1) are currently accessible via the network.

  • 域控制器可能会将以下事件ID 5838记录为 错误。
