AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions MySQL Server versions 8.0.20 and prior

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

Recommendations For versions 8.0.20 and prior, update to a version later than 8.0.20 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation. Avoid using the MySQL Server with high-privileged access until the issue is resolved. At the moment, there is no information about additional mitigation measures.
