REDHAT-BUG-2504855: Medium severity Oracle MySQL Server vulnerability

Q: Who is realistically exposed to this issue?

Exposure is limited to affected MySQL Server and MySQL Cluster deployments where an attacker can log on to the infrastructure hosting the database software and already has high privileges. The issue is locally exploitable, not remotely exploitable under the supplied CVSS vector.

Q: What access does an attacker need to exploit it?

An attacker needs local infrastructure access, a valid logon, and high privileges. Exploitation is rated difficult and does not require user interaction.

Q: Which versions are affected?

Affected MySQL Server versions are 8.4.0 through 8.4.10 and 9.7.0 through 9.7.1. Affected MySQL Cluster versions are 8.0.0 through 8.0.47, 8.4.0 through 8.4.10, and 9.7.0 through 9.7.1.

Q: What is the potential impact of successful exploitation?

A successful attack can result in takeover of MySQL Server or MySQL Cluster. Confidentiality, integrity, and availability can all be affected.
