Deeper analysis
CVE-2022-21289 affects the Cluster: General component of Oracle MySQL Cluster in versions 7.4.34 and earlier, 7.5.24 and earlier, 7.6.20 and earlier, and 8.0.27 and earlier. It is a difficult-to-exploit flaw that can be leveraged by a high-privileged attacker who already has access to the physical network segment connected to the affected hardware.
An attacker meeting those prerequisites can achieve full takeover of the MySQL Cluster instance, resulting in loss of confidentiality, integrity, and availability. Successful exploitation also requires a separate user to perform an action that completes the attack.
Oracle’s January 2022 Critical Patch Update and related NetApp security advisories address the issue, directing administrators to apply the corresponding fixes for the listed MySQL Cluster releases. The referenced Zero Day Initiative advisory provides additional technical context on the vulnerability.
The associated EPSS score has remained flat at its peak value of 0.1143 with no material upward movement after disclosure.
