CVE-2022-21308
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 · uneditedVulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: General). Supported versions that are affected are 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 confidenceVulnerability in Oracle MySQL Cluster (versions 8.0.27 and prior) in the Cluster: General component. A high-privileged attacker with physical access to the network segment where MySQL Cluster operates can exploit this difficult-to-exploit flaw, which also requires human interaction from a person other than the attacker. Successful exploitation results in complete takeover of the MySQL Cluster with high impact to confidentiality, integrity, and availability.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed MySQL server versionRun 'mysql --version' or log into MySQL and execute 'SELECT VERSION();' to obtain the exact version stringAffected if The version returned is between 8.0.0 and 8.0.27 inclusive
-
Confirm MySQL Cluster is in useCheck if the 'ndb' or 'ndbcluster' storage engine is available and in use. Run 'SHOW ENGINES;' or query 'SHOW VARIABLES LIKE 'have_ndbcluster';' in MySQLAffected if The ndbcluster engine is present and active, indicating MySQL Cluster is deployed
-
Check for Netapp Oncommand Insight installationInspect system for Netapp Oncommand Insight software components, typically installed on Windows or Linux servers. Look for installation directories or use system inventory toolsAffected if Netapp Oncommand Insight is installed on the system
-
Check for Netapp Oncommand Workflow Automation installationInspect system for Netapp Oncommand Workflow Automation software components. Look for installation directories or use system inventory toolsAffected if Netapp Oncommand Workflow Automation is installed on the system
A user is affected if they run Oracle MySQL Cluster version 8.0.0 through 8.0.27, or have Netapp Oncommand Insight or Netapp Workflow Automation installed, with the additional requirement that the attacker has physical access to the network segment and can leverage human interaction

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 · scopedApply the relevant Oracle Critical Patch Update or upgrade MySQL Cluster to a version beyond 8.0.27. Additionally, enforce strict physical security and network segmentation to limit access to the hardware and communication segments where MySQL Cluster executes.
MySQL 8.0.28 or later for the Cluster component
- 1. For MySQL Cluster: Upgrade MySQL Server from 8.0.27 or earlier to version 8.0.28 or later, as this version addresses the vulnerability in the Cluster component.
- 2. For NetApp Oncommand Insight and Oncommand Workflow Automation: These products are listed as affected with 'all versions'. Consult NetApp's security advisory (security.netapp.com) for specific remediation guidance, as these products may require alternative mitigation or may be end-of-life with no patch available.
- 3. If upgrading is not immediately feasible, implement network segmentation to restrict physical access to the communication segment where MySQL Cluster operates, as the CVSS vector indicates the attacker requires Adjacent (AV:A) network access.
