CVE-2023-22026

Name of the Vulnerable Software and Affected Versions MySQL Server versions 5.7.42 and prior MySQL Server versions 8.0.31 and prior

Description A vulnerability in the MySQL Server product allows a high-privileged attacker with network access via multiple protocols to compromise the server. Successful attacks can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of the MySQL Server. The issue is related to insufficient input validation in the Server: Optimizer component.

Recommendations For MySQL Server versions 5.7.42 and prior, update to a version later than 5.7.42 to resolve the issue. For MySQL Server versions 8.0.31 and prior, update to a version later than 8.0.31 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
