Name of the Vulnerable Software and Affected Versions Oracle MySQL versions 8.0.15 and prior

Description The issue is related to insufficient access control in the MySQL Server component, specifically in the Server: Optimizer subcomponent. This allows an attacker with network access via multiple protocols to compromise the MySQL Server. Successful attacks can result in the ability to cause a hang or frequently repeatable crash (complete DOS) of the MySQL Server. The vulnerability can be exploited by an attacker to disrupt the service using the MySQL protocol.

Recommendations For versions 8.0.15 and prior, update to a version later than 8.0.15 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
