Oracle · Mysql Server · CVE-2023-21912
**Name of the Vulnerable Software and Affected Versions**
MySQL Server versions 5.7.41 and prior
MySQL Server versions 8.0.30 and prior
**Description**
The issue allows an unauthenticated attacker with network access via multiple protocols to compromise MySQL Server, resulting in the unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. This is due to insufficient input validation in the Server: Security: Privileges component.
**Recommendations**
For MySQL Server versions 5.7.41 and prior, update to a version later than 5.7.41.
For MySQL Server versions 8.0.30 and prior, update to a version later than 8.0.30.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
