VectorAV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions MySQL Server versions 8.0.40 and prior MySQL Server versions 8.4.3 and prior MySQL Server versions 9.1.0 and prior
Description The vulnerability in the MySQL Server product of Oracle MySQL is related to the Server: Packaging component and can be exploited to cause a denial of service. This can be achieved by a high-privileged attacker with network access via multiple protocols, resulting in the ability to cause a hang or frequently repeatable crash of MySQL Server. The issue is related to resource exhaustion.
Recommendations For MySQL Server versions 8.0.40 and prior, update to a version later than 8.0.40 to resolve the issue. For MySQL Server versions 8.4.3 and prior, update to a version later than 8.4.3 to resolve the issue. For MySQL Server versions 9.1.0 and prior, update to a version later than 9.1.0 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
