Answer

  • CVE-2022-38023 is only for RPC_NETLOGON, not specifically for NTLM.
  • RPC_NETLOGON is only used when communicating to Active Directory Domain Controllers
  • CVE-2022-38023 does not impact local authenticated CIFS users

Additional Information

 
  • To ensure that local accounts are being evaluated, the client has to pass credentials as "cifsservername\local-user".
  • Here's an example of a new use using that format: net use z: \\IP_SVM\share1 /user:cifsservername\local-user"
  • If the credentials are not passed as "cifsservername\local-user", ONTAP will attempt to use passthrough and refer those credentials to the local DC
