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

Name of the Vulnerable Software and Affected Versions Oracle MySQL Server versions 5.7.33 and prior Oracle MySQL Server versions 8.0.23 and prior

Description The issue is related to insufficient input validation in the Server: Group Replication Plugin 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 5.7.33 and prior, update to a version later than 5.7.33. For Oracle MySQL Server versions 8.0.23 and prior, update to a version later than 8.0.23. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
