CVE-2024-21198

Name of the Vulnerable Software and Affected Versions: MySQL Server versions 8.0.39 and prior MySQL Server versions 8.4.2 and prior MySQL Server versions 9.0.1 and prior

Description: The issue is related to insufficient input validation in the Server: DDL component of Oracle MySQL Server. It allows a high-privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.

Recommendations: For MySQL Server versions 8.0.39 and prior, update to a version later than 8.0.39 to resolve the issue. For MySQL Server versions 8.4.2 and prior, update to a version later than 8.4.2 to resolve the issue. For MySQL Server versions 9.0.1 and prior, update to a version later than 9.0.1 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
