CVE-2024-21194

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 the InnoDB component of the MySQL Server product. 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. The vulnerability is easily exploitable and can be triggered by an attacker with network access.

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.
