Name of the Vulnerable Software and Affected Versions Oracle MySQL versions 5.6.42 and prior Oracle MySQL versions 5.7.24 and prior Oracle MySQL versions 8.0.13 and prior

Description The issue is related to insufficient access control in the MySQL Server component, specifically in the Server: Replication subcomponent. This allows a high-privileged 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 of the MySQL Server, leading to a denial of service.

Recommendations For Oracle MySQL version 5.6.42 and prior, update to a version later than 5.6.42 to resolve the issue. For Oracle MySQL version 5.7.24 and prior, update to a version later than 5.7.24 to resolve the issue. For Oracle MySQL version 8.0.13 and prior, update to a version later than 8.0.13 to resolve the issue. As a temporary workaround, consider restricting access to the Server: Replication component to minimize the risk of exploitation.
