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
Vulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: General). Supported versions that are affected are 7.4.34 and prior, 7.5.24 and prior, 7.6.20 and prior and 8.0.27 and prior. Difficult to exploit vulnerability allows high privileged attacker with access to the physical communication segment attached to the hardware where the MySQL Cluster executes to compromise MySQL Cluster. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of MySQL Cluster. CVSS 3.1 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H).

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

Vulnerability in MySQL Cluster allows a high-privileged attacker with physical access to the network segment to compromise the cluster. The attack is difficult to exploit, requires human interaction, and can result in complete takeover of MySQL Cluster due to high impact on confidentiality, integrity, and availability.

MitigationApply Oracle's Critical Patch Update for this vulnerability or upgrade to MySQL Cluster 7.4.35+, 7.5.25+, 7.6.21+, or 8.0.28+. Implement network segmentation and physical security controls as defense-in-depth measures.

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 if MySQL Cluster is installed
    Run 'mysql --version' or check for mysqld process, or examine MySQL error log for version string
    Affected if MySQL Cluster version falls within 7.4.0-7.4.34, 7.5.0-7.5.24, 7.6.0-7.6.20, or 8.0.0-8.0.27
  2. Check NetApp Oncommand Insight installation
    Verify if Oncommand Insight software is present on the system using package manager or installed applications list
    Affected if Oncommand Insight is installed (all versions are affected)
  3. Check NetApp Oncommand Workflow Automation installation
    Verify if Oncommand Workflow Automation software is present on the system using package manager or installed applications list
    Affected if Oncommand Workflow Automation is installed (all versions are affected)
  4. Verify network exposure and physical access controls
    Assess whether the MySQL Cluster or NetApp systems are on a network segment accessible to untrusted users and whether physical security controls are in place
    Affected if System is on an exposed network segment without adequate physical security controls

You are affected if running any version of MySQL Cluster within the affected ranges (7.4.x through 8.0.27) or any version of NetApp Oncommand Insight or Oncommand Workflow Automation, and the attacker has physical access to the network segment.

Upgrade available Upgrade to a release after 8.0.27
Interim mitigation

Apply Oracle's Critical Patch Update for this vulnerability or upgrade to MySQL Cluster 7.4.35+, 7.5.25+, 7.6.21+, or 8.0.28+. Implement network segmentation and physical security controls as defense-in-depth measures.

Recommended fix High confidence

MySQL Cluster 7.4.35+, 7.5.25+, 7.6.21+, or 8.0.28+ (or latest 8.0.x stable release)

  1. 1. Identify the currently running MySQL Cluster version using: `ndb_mgm -e 'show'` or checking mysqld version
  2. 2. For MySQL Cluster 7.4.x: Upgrade to version 7.4.35 or later
  3. 3. For MySQL Cluster 7.5.x: Upgrade to version 7.5.25 or later
  4. 4. For MySQL Cluster 7.6.x: Upgrade to version 7.6.21 or later
  5. 5. For MySQL Cluster 8.0.x: Upgrade to version 8.0.28 or later
  6. 6. Download the appropriate MySQL Cluster distribution from dev.mysql.com or your organization's package repository
  7. 7. Perform a rolling upgrade following Oracle's documented procedure to maintain cluster availability
  8. 8. After upgrade, verify the cluster is operational and the new version is running: `ndb_mgm -e 'show'`
Caveat Minor version upgrades within same major.minor series typically have low risk; however, always review Oracle's release notes for deprecation notices and ensure application compatibility before production upgrade
