CVE-2021-2202

Name of the Vulnerable Software and Affected Versions Oracle MySQL Server versions 5.7.32 and prior Oracle MySQL Server versions 8.0.22 and prior

Description The issue is related to insufficient input validation in the Server: Replication component of the Oracle MySQL Server system. This can be exploited by a remote attacker to cause a denial of service using the MySQL network protocol. Successful attacks can result in the ability to cause a hang or frequently repeatable crash of the MySQL Server.

Recommendations For versions 5.7.32 and prior, update to a version later than 5.7.32 to resolve the issue. For versions 8.0.22 and prior, update to a version later than 8.0.22 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
