CVE-2023-22111

Name of the Vulnerable Software and Affected Versions MySQL Server versions 8.0.33 and prior

Description The issue is related to the MySQL Server product of Oracle MySQL, specifically the Server: UDF component. It allows a high privileged attacker with network access via multiple protocols to compromise the MySQL Server. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of the MySQL Server. The vulnerability is easily exploitable and can be used to perform a denial-of-service (DoS) attack.

Recommendations For versions 8.0.33 and prior, update to a version later than 8.0.33 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation. Additionally, monitor the server for signs of a denial-of-service attack and have a plan in place to quickly respond to such an incident.
