Описание

Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Optimizer). Supported versions that are affected are MySQL Server: 8.4.0-8.4.12, 9.7.0-9.7.3, 26.7.0-26.7.1; MySQL Cluster: 8.0.0-8.0.49, 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server, MySQL Cluster. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server, MySQL Cluster. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

A flaw was found in the MySQL Server Optimizer. A remote attacker with high privileges can exploit this vulnerability over network protocols to cause the server to hang or crash repeatedly. This issue results in a complete denial of service (DoS) for the database service.

Отчет

This flaw is rated as Moderate impact for Red Hat Enterprise Linux because exploitation requires an attacker to already possess high administrative privileges on the target database instance. Although an authenticated administrator can trigger a denial of service by causing the database server process to terminate unexpectedly or stop responding during query optimization, the vulnerability does not compromise data confidentiality or integrity. Furthermore, standard database deployments restrict elevated account privileges to authorized administrators, significantly limiting potential exposure.
