Frequently Asked Questions
Which deployments should be prioritized for triage?
Prioritize Oracle MySQL Server versions 8.4.0 through 8.4.12, 9.7.0 through 9.7.3, and 26.7.0 through 26.7.1. For MySQL Cluster, affected ranges are 8.0.0 through 8.0.49, 8.4.0 through 8.4.12, 9.7.0 through 9.7.3, and 26.7.0 through 26.7.1.
What level of access does an attacker need?
An attacker must already be highly privileged and have network access to the affected server or cluster through multiple protocols. No user interaction is required.
What is the expected impact if exploitation succeeds?
Successful exploitation can hang the affected service or cause frequently repeatable crashes, resulting in complete denial of service. The supplied CVSS vector indicates no confidentiality or integrity impact.
How can we determine whether an environment is affected?
Identify whether the deployment is MySQL Server or MySQL Cluster, then compare its exact installed version with the affected version ranges. The available data does not identify any configuration-specific condition that would exclude an affected version.
