CVE-2023-27314
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedONTAP 9 versions prior to 9.8P19, 9.9.1P16, 9.10.1P12, 9.11.1P8, 9.12.1P2 and 9.13.1 are susceptible to a vulnerability which could allow a remote unauthenticated attacker to cause a crash of the HTTP service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceNetApp ONTAP 9 versions prior to 9.8P19, 9.9.1P16, 9.10.1P12, 9.11.1P8, 9.12.1P2 and 9.13.1 contain a pre-authentication vulnerability allowing a remote unauthenticated attacker to crash the HTTP service, resulting in denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed ONTAP versionRun `version` command in ONTAP CLI or use `system node show -fields version` to display the ONTAP versionAffected if The version matches any of these: >= 9.0 and < 9.8, 9.8, 9.9.1, 9.10.0, 9.10.1, 9.12.0, or 9.13.0
-
Confirm HTTP service is enabledCheck if the HTTP service is active by running `system services web show` or verifying that the management interface accepts HTTP connectionsAffected if HTTP service is enabled and accessible on the management interface
You are affected if your ONTAP version matches the affected ranges AND the HTTP management service is enabled and network-accessible.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade ONTAP 9 to version 9.8P19, 9.9.1P16, 9.10.1P12, 9.11.1P8, 9.12.1P2, 9.13.1 or later. Since this is exploitable without authentication, immediately restricting network access to management interfaces should be considered as an interim control.
9.13.1 (or the appropriate patched version: 9.8P19, 9.9.1P16, 9.10.1P12, 9.11.1P8, or 9.12.1P2)
- 1. Identify current ONTAP version using `version -v` command
- 2. Based on current version, determine the minimum required patch release from: 9.8P19, 9.9.1P16, 9.10.1P12, 9.11.1P8, 9.12.1P2, or 9.13.1
- 3. Download the appropriate patch from the NetApp Support Portal (support.netapp.com)
- 4. Review NetApp upgrade documentation and release notes for pre-upgrade requirements
- 5. Create a backup of the cluster configuration
- 6. Schedule a maintenance window as upgrade will require a brief service interruption
- 7. Apply the patch following NetApp's documented upgrade procedure for the specific version
- 8. Verify the upgrade was successful and HTTP service is operational
