CVE-2022-21490

Name of the Vulnerable Software and Affected Versions Oracle MySQL Cluster versions 7.4.35 and prior Oracle MySQL Cluster versions 7.5.25 and prior Oracle MySQL Cluster versions 7.6.21 and prior Oracle MySQL Cluster versions 8.0.28 and prior

Description The issue is related to insufficient input validation in the Cluster: General component of Oracle MySQL Cluster, allowing a high-privileged attacker with access to the physical communication segment to compromise the MySQL Cluster. Successful attacks require human interaction from a person other than the attacker and can result in the takeover of MySQL Cluster.

Recommendations For Oracle MySQL Cluster version 7.4.35 and prior, update to a version later than 7.4.35. For Oracle MySQL Cluster version 7.5.25 and prior, update to a version later than 7.5.25. For Oracle MySQL Cluster version 7.6.21 and prior, update to a version later than 7.6.21. For Oracle MySQL Cluster version 8.0.28 and prior, update to a version later than 8.0.28. As a temporary workaround, consider restricting access to the physical communication segment attached to the hardware where the MySQL Cluster executes to minimize the risk of exploitation.
