| Vector | AV:N/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
MySQL Server versions 5.7.33 and prior
MySQL Server versions 8.0.23 and prior
Description
The issue is related to insufficient input validation in the MySQL Server product of Oracle MySQL, specifically in the Server: DML component. This can be exploited by a remote attacker to cause a denial of service via 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 MySQL Server versions 5.7.33 and prior, update to a version later than 5.7.33 to resolve the issue.
For MySQL Server versions 8.0.23 and prior, update to a version later than 8.0.23 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
