CVE-2022-21285

Takeover by adjacent high-privileged attackers

Published Jan 19, 2022 · Updated Sep 24, 2024

An unspecified flaw in affected Oracle MySQL Cluster releases allows attackers to take over the cluster from an adjacent network. Oracle identifies only the Cluster: General component and multiple protocols; it has not published the flawed locus or incorrect operation. Successful exploitation requires attackers with high privileges on the physical communication segment and interaction by another person.
