CVE-2021-2230

Name of the Vulnerable Software and Affected Versions Oracle MySQL Server versions 8.0.23 and prior

Description The issue is related to insufficient input validation in the Server: Optimizer component of Oracle MySQL Server. 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 Oracle MySQL Server versions 8.0.23 and prior, update to a version later than 8.0.23 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
