Name of the Vulnerable Software and Affected Versions:
MySQL Server versions 8.0.36 and prior
MySQL Server versions 8.3.0 and prior
Description:
The issue is related to insufficient input validation in the Server: Optimizer component of Oracle MySQL Server. This can be exploited by a high-privileged attacker with network access via multiple protocols to compromise MySQL Server, resulting in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.
Recommendations:
For MySQL Server versions 8.0.36 and prior, update to a version that includes the fix for this issue.
For MySQL Server versions 8.3.0 and prior, update to a version that includes the fix for this issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
