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, potentially achieving full takeover (C:H/I:H/A:H). Exploitation is difficult, requiring adjacent network access, high privileges, and human interaction from a person other than the attacker.

MitigationUpgrade MySQL Cluster to a patched version (8.0.28 or later, or newer versions for 7.4/7.5/7.6 branches). If immediate patching is not feasible, restrict physical access to the network segment and enforce strict access controls on high-privileged accounts.

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 MySQL Cluster installation
    Run 'mysql --version' or check for ndbd/ndb_mgmd processes via 'ps aux | grep ndb' to verify MySQL Cluster components are present
    Affected if MySQL Cluster binaries or processes are found on the system
  2. Identify MySQL Cluster version
    Execute 'mysql --version' or log into mysql and run 'SELECT VERSION();' to obtain the exact version string
    Affected if The installed version matches 7.4.x, 7.5.x, 7.6.x, or 8.0.x
  3. Compare version against affected ranges
    Check if 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
    Affected if Installed version is >= 7.4.0 and <= 7.4.34, OR >= 7.5.0 and <= 7.5.24, OR >= 7.6.0 and <= 7.6.20, OR >= 8.0.0 and <= 8.0.27
  4. Check for NetApp Oncommand Insight
    List installed packages or running services related to Oncommand Insight via package manager or service list
    Affected if NetApp Oncommand Insight is installed (all versions are affected)
  5. Check for NetApp Oncommand Workflow Automation
    List installed packages or running services related to Oncommand Workflow Automation via package manager or service list
    Affected if NetApp Oncommand Workflow Automation is installed (all versions are affected)

User is 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, or if NetApp Oncommand Insight or Oncommand Workflow Automation are installed.

dbcve · scoped
Upgrade available Upgrade to a release after 8.0.27
Interim mitigation

Upgrade MySQL Cluster to a patched version (8.0.28 or later, or newer versions for 7.4/7.5/7.6 branches). If immediate patching is not feasible, restrict physical access to the network segment and enforce strict access controls on high-privileged accounts.

Recommended fix Moderate confidence

MySQL Cluster 7.4.35+, 7.5.25+, 7.6.21+, or 8.0.28+ depending on your current major version

  1. Identify the currently running MySQL Cluster version using `mysql --version` or checking the ndb_mgm client
  2. For MySQL Cluster 7.4.x: upgrade to version 7.4.35 or later
  3. For MySQL Cluster 7.5.x: upgrade to version 7.5.25 or later
  4. For MySQL Cluster 7.6.x: upgrade to version 7.6.21 or later
  5. For MySQL Cluster 8.0.x: upgrade to version 8.0.28 or later
  6. Download the appropriate MySQL Cluster distribution from https://downloads.mysql.com/archives/community/
  7. Stop the MySQL Cluster services on all nodes (ndb_mgmd, ndbd, mysqld)
  8. Install the new MySQL Cluster packages on all cluster nodes
Caveat Upgrading MySQL Cluster requires careful planning; ensure compatibility with application MySQL clients and test in staging first as minor version upgrades may introduce behavioral changes
