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 · unedited
Clustered Data ONTAP versions prior to 9.1P15 and 9.3 prior to 9.3P7 are susceptible to a vulnerability which discloses sensitive information to an unauthenticated user.

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 confidence

Clustered Data ONTAP versions prior to 9.1P15 and 9.3 prior to 9.3P7 contain an information disclosure vulnerability that allows unauthenticated attackers to gain access to sensitive system information without requiring valid credentials.

MitigationUpgrade Clustered Data ONTAP to version 9.1P15 or later, or 9.3P7 or later, to resolve the vulnerability.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Clustered Data ONTAP is installed
    Run the command 'system node show' or 'version' in the ONTAP CLI to identify the system and verify it is a Clustered Data ONTAP storage system.
    Affected if The system is running Clustered Data ONTAP and responds to ONTAP CLI commands.
  2. Retrieve the ONTAP version
    Execute the 'version' command in the ONTAP CLI or run 'system node show -fields version' to obtain the exact installed version number.
    Affected if The command returns a version number.
  3. Compare version against affected ranges
    Check if the installed version falls within: 9.0.x, any 9.1 version prior to 9.1P15, or any 9.3 version prior to 9.3P7. These versions contain the vulnerability.
    Affected if The installed version is 9.0.x, 9.1.x prior to 9.1P15, or 9.3.x prior to 9.3P7.
  4. Verify the system is network-accessible
    Confirm that the ONTAP management interface or API endpoints are reachable from network locations, as the vulnerability allows unauthenticated attackers to access sensitive system information remotely.
    Affected if The ONTAP management LIF or API is exposed to untrusted networks without proper access controls.

A system is affected if it runs Clustered Data ONTAP version 9.0.x, 9.1.x before 9.1P15, or 9.3.x before 9.3P7 and has its management interface network-accessible.
