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 through difficult-to-exploit attacks requiring human interaction. Successful exploitation can result in complete takeover of MySQL Cluster.

MitigationUpgrade MySQL Cluster to version 7.4.35 or later, 7.5.25 or later, 7.6.21 or later, or 8.0.28 or later. If immediate patching is not possible, restrict physical access to network segments 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. Check if MySQL Cluster processes are running
    Look for ndbd, ndb_mgmd, or mysqld processes with NDB support: ps aux | grep -E 'ndbd|ndb_mgmd' or check if MySQL was built with NDB cluster support via mysqld --verbose --help 2>/dev/null | grep -i ndb
    Affected if MySQL Cluster processes (ndbd, ndb_mgmd) are running or NDB storage engine is available
  2. Determine installed MySQL Cluster version
    Run mysql -V or connect to MySQL and execute SELECT VERSION(); and SELECT @@version_comment; to identify the exact version string
    Affected 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
  3. Check for NetApp Oncommand Insight installation
    Look for Oncommand Insight installation directories, services, or executables. Common paths include /opt/netapp/oci, /usr/local/oci, or check installed packages: dpkg -l | grep -i oncommand or rpm -qa | grep -i oncommand
    Affected if Oncommand Insight is installed (all versions affected)
  4. Check for NetApp Oncommand Workflow Automation installation
    Look for Oncommand Workflow Automation installation directories, services, or executables. Check installed packages: dpkg -l | grep -i oncommand or rpm -qa | grep -i oncommand
    Affected if Oncommand Workflow Automation is installed (all versions affected)

Environment is affected if MySQL Cluster version is 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 is installed regardless of version

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

Upgrade MySQL Cluster to version 7.4.35 or later, 7.5.25 or later, 7.6.21 or later, or 8.0.28 or later. If immediate patching is not possible, restrict physical access to network segments and enforce strict access controls on high-privileged accounts.

Recommended fix High confidence

MySQL Cluster 8.0.28+ (or 8.0.x latest), 7.6.21+, 7.5.25+, 7.4.35+ | NetApp patches per respective advisories

  1. For MySQL Cluster: Upgrade MySQL Server to version 8.0.28 or higher for the 8.0 branch
  2. For MySQL Cluster 7.4.x: Upgrade to version 7.4.35 or higher
  3. For MySQL Cluster 7.5.x: Upgrade to version 7.5.25 or higher
  4. For MySQL Cluster 7.6.x: Upgrade to version 7.6.21 or higher
  5. For NetApp Oncommand Insight: Apply the appropriate patch from NetApp advisory NTAP-20220120 or consult support.netapp.com for the specific patch for your version
  6. For NetApp Oncommand Workflow Automation: Apply the appropriate patch from NetApp advisory NTAP-20220120 or consult support.netapp.com for the specific patch for your version
  7. After upgrade, verify MySQL Cluster status and ensure all nodes are operational
  8. Test any critical applications that depend on MySQL Cluster functionality
Caveat MySQL Cluster upgrades may require cluster rolling restart; review Oracle MySQL upgrade documentation for compatibility considerations. NetApp product upgrades should follow standard NetApp upgrade procedures.
