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
SMB in Data ONTAP operating in 7-Mode versions prior to 8.2.5P3 has weak cryptography which when exploited could lead to information disclosure or addition or modification of data.

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

SMB protocol in NetApp Data ONTAP 7-Mode prior to version 8.2.5P3 uses weak cryptographic algorithms, allowing remote attackers to intercept or manipulate SMB traffic to achieve information disclosure or unauthorized data modification.

MitigationUpgrade Data ONTAP 7-Mode to version 8.2.5P3 or later to obtain corrected SMB cryptography implementations.

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. Identify the Data ONTAP deployment mode
    Run the command 'version' or check the system prompt. Look for indication of 7-Mode versus clustered Data ONTAP (cDOT). 7-Mode systems display a numeric version, while clustered Data ONTAP shows Cluster-Mode.
    Affected if The system is running Data ONTAP 7-Mode (not clustered Data ONTAP)
  2. Determine the installed Data ONTAP 7-Mode version
    Run the 'version' command and note the exact version number displayed (for example, 8.1.4, 8.2.0, 8.2.5, etc.).
    Affected if The version is 8.2.5 or any version below 8.2.5 (for example, 8.2.4, 8.2.0, 8.1.x, 8.0.x)
  3. Verify SMB service is enabled and configured
    Run 'smb status' or check the SMB configuration via 'options smb' to confirm SMB is actively serving shares.
    Affected if SMB is enabled and the system is configured to serve SMB shares to clients
  4. Inspect SMB security settings (optional)
    Check SMB encryption and signing options via 'options smb' or 'smb encrypt' settings if available in the configuration.
    Affected if Weak SMB encryption or signing algorithms are in use (legacy or disabled security settings)

You are affected if the system runs Data ONTAP 7-Mode with SMB enabled and the version is 8.2.5 or any earlier version (the vulnerability is fixed in version 8.2.5P3 and later).

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.

dbcve · scoped
Upgrade available Upgrade to 8.2.5 or later
Fixed in 8.2.5
Interim mitigation

Upgrade Data ONTAP 7-Mode to version 8.2.5P3 or later to obtain corrected SMB cryptography implementations.

Recommended fix High confidence

Data ONTAP 8.2.5P3 or later

  1. Identify the current Data ONTAP 7-Mode version by running the 'version' command
  2. Obtain Data ONTAP 8.2.5P3 or a later fixed release from the NetApp Support site
  3. Review NetApp's upgrade documentation for 7-Mode systems
  4. Perform a backup of critical data before upgrading
  5. Follow the documented upgrade procedure to install 8.2.5P3 or later
  6. Verify the SMB version and confirm the upgrade was successful using 'smb status' or similar commands
Caveat Minor patch upgrade within 8.x lineage; standard upgrade risks apply (review release notes for any configuration changes)

Generated from the published advisory — verify against the referenced sources before acting.
