Name of the Vulnerable Software and Affected Versions MySQL Server versions 5.6.34 and earlier MySQL Server versions 5.7.16 and earlier

Description The issue is related to inadequate access control in the MySQL Server component, specifically in the Server: Replication subcomponent. 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 MySQL Server versions 5.6.34 and earlier, update to a version later than 5.6.34 to resolve the issue. For MySQL Server versions 5.7.16 and earlier, update to a version later than 5.7.16 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
