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
NetApp Clustered Data ONTAP 8.3.1 does not properly verify X.509 certificates from TLS servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

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 · moderate confidence

NetApp Clustered Data ONTAP 8.3.1 fails to properly validate X.509 certificates during TLS handshakes, allowing attackers to present malicious certificates and intercept encrypted communications. This certificate validation bypass enables man-in-the-middle attacks where attackers can impersonate trusted TLS servers and capture sensitive data in transit.

MitigationApply the vendor patch for this vulnerability. If immediate patching is not feasible, implement network segmentation and TLS-inspecting proxies or VPN controls to mitigate MITM risks on affected paths.

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 NetApp Clustered Data ONTAP is installed
    Use system inventory or NetApp commands such as 'system node show' or check the storage system identification to verify the product name.
    Affected if The system is running NetApp Clustered Data ONTAP.
  2. Check the installed version
    Execute the version command for Clustered Data ONTAP (e.g., 'version' or 'system node image show' to view installed software versions).
    Affected if The version reported is exactly 8.3.1.
  3. Verify TLS functionality is in use
    Check if TLS-enabled services or protocols are configured (e.g., review TLS/SSL-enabled interfaces, check for HTTPS, NDMP over TLS, or other encrypted management access).
    Affected if TLS is enabled or configured on the system and the version is 8.3.1.

The environment is affected only if NetApp Clustered Data ONTAP version 8.3.1 is installed and TLS certificate validation is in use.
