Base vector

AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: MySQL Server versions 8.0.22 and prior

Description: The issue is related to insufficient input validation in the Server: Stored Procedure component of 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 8.0.22 and prior, update to a version later than 8.0.22 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation. Additionally, restrict access to the Server: Stored Procedure component to prevent potential attacks.
