ENS for Storage Authentication Failure - CVE-2022-38023

Technical Articles ID: KB96598
Last Modified: 2023-07-04 08:46:58 Etc/GMT

Environment

Endpoint Security Storage Protection (ENSSP) 2.x

Problem

ENS for Storage using Windows NTLM authentication might fail due to enforcement of Net logon RPC sealing via Windows updates.

ENS for Storage experiences authentication failures, when using the NetApp OnTap AV Connector.

Cause

Owing to security vulnerability CVE-2022-38023, Microsoft updated Windows to use Net Logon RPC sealing.
This update sets the enforcement mode for Netlogn RPCSeal, causing clients to experience Windows/NTLM authentication failures.

This change inadvertently impacts the ability of ENS for Storage to successfully logon to the OnTap shares and you then see scan failures for these shares.

Solution

Upgrade the existing versions of ONTAP releases to allow the continued use of Windows NTLM authentication.
For more information, see the NetApp Support Bulletin.
