Deeper analysis
Vulnerability CVE-2022-21279 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 requires an attacker to be positioned on the same physical network segment as the target hardware and to obtain high privileges along with interaction from another user.
An attacker meeting those conditions can achieve full takeover of the MySQL Cluster instance, resulting in loss of confidentiality, integrity, and availability. The CVSS 3.1 vector reflects the combination of adjacent-network access, high attack complexity, high privileges, and required user interaction.
Oracle's January 2022 Critical Patch Update and the related NetApp advisory address the issue through vendor-supplied patches for the affected MySQL Cluster releases. Organizations are advised to apply the updates to eliminate the vulnerability.
The associated EPSS score reached a peak of 0.1491 with no material increase after disclosure.
