AI-suggested
1. Apply official Oracle patches or updates for MySQL Cluster as soon as they become available to remediate the vulnerability. 2. Restrict network access to MySQL Cluster nodes using firewalls and network segmentation to limit exposure to trusted hosts and administrators only. 3. Enforce strict access controls and least privilege principles for users with high privileges on MySQL Cluster to reduce the risk of insider threats or privilege escalation exploitation. 4. Monitor and audit privileged user activities and database logs for unusual or unauthorized data modification attempts. 5. Implement robust backup and recovery procedures to restore data integrity and availability in case of successful exploitation. 6. Consider deploying intrusion detection/prevention systems (IDS/IPS) to detect anomalous network traffic patterns targeting MySQL Cluster protocols. 7. Regularly review and update security policies related to database access and network configurations to minimize attack vectors. 8. Conduct penetration testing and vulnerability assessments focusing on MySQL Cluster environments to identify and remediate potential weaknesses proactively.
Description
Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected are 8.0.0-8.0.41, 8.4.0-8.4.4 and 9.0.0-9.2.0. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server as well as unauthorized update, insert or delete access to some of MySQL Server accessible data. CVSS 3.1 Base Score 5.5 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H).
