CVE-2022-21280
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 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 confidenceThis is a vulnerability in the MySQL Cluster product's Cluster:General component affecting versions 7.4.34 and prior, 7.5.24 and prior, 7.6.20 and prior, and 8.0.27 and prior. The flaw allows a high-privileged attacker with physical access to the communication segment attached to the hardware where MySQL Cluster executes to compromise the cluster, potentially achieving full takeover. Exploitation is difficult, requiring both physical proximity access and human interaction from a non-attacker person.

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 if MySQL Cluster is installedCheck for ndbd or ndbmtd processes running, or look for MySQL Cluster binaries in common installation paths like /usr/sbin/ndbd, /usr/bin/mysql, or check for ndbcluster in my.cnf configuration files.Affected if MySQL Cluster binaries or ndbcluster configuration is found on the system.
-
Determine the installed MySQL Cluster versionRun 'mysql --version' or check the ndbd --version output if available, or inspect the installed RPM/deb package version using package manager commands like 'rpm -qa | grep mysql-cluster' or 'dpkg -l | grep mysql-cluster'.Affected if The version number returned is 7.4.x at 34 or lower, 7.5.x at 24 or lower, 7.6.x at 20 or lower, or 8.0.x at 27 or lower.
-
Verify the Cluster:General component is in useCheck the my.cnf configuration file for the ndbcluster storage engine being enabled (look for 'ndbcluster' under [mysqld] section) and check for ndb-connectstring parameters pointing to management nodes.Affected if The ndbcluster storage engine is enabled in the MySQL configuration.
-
Check physical access exposureReview network documentation and physical security controls to determine if the network segment connected to the MySQL Cluster hardware is accessible to unauthorized high-privileged users.Affected if The hardware hosting MySQL Cluster or its communication network segment lacks physical security controls or is accessible to non-authorized personnel.
You are affected if MySQL Cluster with ndbcluster enabled is running a version within 7.4.x through 7.4.34, 7.5.x through 7.5.24, 7.6.x through 7.6.20, or 8.0.x through 8.0.27, and the hardware or its network segment has insufficient physical access controls.

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 · scopedUpgrade MySQL Cluster to version 8.0.28 or later (and corresponding patched versions for 7.4.x, 7.5.x, 7.6.x branches). Additionally, enforce strict physical security controls on network segments and hardware hosting the cluster to reduce attack surface.
MySQL Cluster 7.4.35+/7.5.25+/7.6.21+/8.0.28+ (first version beyond each affected branch)
- 1. Identify the currently running MySQL Cluster version using 'mysql --version' or checking the ndb_mgmd process
- 2. Plan maintenance window as this upgrade requires cluster downtime
- 3. Backup all MySQL Cluster data using mysqldump orndb_desc backup
- 4. For MySQL Cluster 7.4.x: Upgrade to version 7.4.35 or later
- 5. For MySQL Cluster 7.5.x: Upgrade to version 7.5.25 or later
- 6. For MySQL Cluster 7.6.x: Upgrade to version 7.6.21 or later
- 7. For MySQL Cluster 8.0.x: Upgrade to version 8.0.28 or later
- 8. Download MySQL Cluster from official Oracle MySQL downloads page
