Frequently Asked Questions
Which deployments are affected?
Affected supported versions are MySQL Server 9.7.0 through 9.7.3 and 26.7.0 through 26.7.1, and MySQL Cluster 9.7.0 through 9.7.3 and 26.7.0 through 26.7.1. The affected component is Server: RAPID.
What level of access does an attacker need?
An attacker needs high privileges and network access through multiple protocols. No user interaction is required, and exploitation is rated as difficult.
What is the expected impact if exploitation succeeds?
Successful exploitation can allow an attacker to hang the server or cause frequently repeatable crashes, resulting in complete denial of service. The stated CVSS impacts are limited to availability; confidentiality and integrity impacts are not listed.
How can I determine whether my environment is exposed?
Identify whether you run MySQL Server or MySQL Cluster and compare the deployed version to the affected ranges. Exposure also requires that a high-privileged attacker can reach the service over the relevant network protocols.
