Hello,

There is a KB: https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/Microsoft_Security_Advisory%3A_CVE-2020-1472_impact_on_NetApp_appliance_running_CIFS_NFS_utilizing_Netlogon_servers

Apparently this is your case:

7-Mode supports Netlogon Secure Channel on fixed releases (8.2.5P5 7-Mode)
Review the details in 1343982: Support Netlogon Secure Channel in 7-mode for CVE-2020-1472
- Workaround 1: NetApp recommendation is to upgrade to 8.2.5P5
  - A new option was introduced to enable support for secure netlogon (cifs.netlogon.secure_channel.enable)
  - This option is vfiler scoped. It must be enabled on all vfilers involved in domain authentication
- Workaround 2: Microsoft has a workaround to allow vulnerable netlogon secure connections via GPO
For more information, contact Netapp Technical Support

I guess you gotta go with workaround 2. I believe this system does not have support and running an upgrade would be risky.

Regards,

Pedro

Sorry I did not get what you mean to say.

I think you should follow the Microsoft workaround: https://support.microsoft.com/en-us/topic/how-to-manage-the-changes-in-netlogon-secure-channel-connections-associated-with-cve-2020-1472-f7e8cc17-0309-1d6a-304e-5ba73cd1a11e#bkmk_thegrouppolicy

Hello my friend,

Sorry I won't be able to do that. But try to find this security policy on your windows machine/GPO:

You got to ALLOW the setting (this will make your environment susceptible to security risks). If your system is 7-mode, this appears to be the only option. If you are running ONTAP and have a support contact, open a case with NetApp. IF you don't have a support contract, then you should stick with the workaround that I mentioned.

Regards,

Pedro
