Описание

Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Pluggable Auth). 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. Difficult to exploit vulnerability allows unauthenticated 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 as well as unauthorized update, insert or delete access to some of MySQL Server, MySQL Cluster accessible data. CVSS 3.1 Base Score 6.5 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H).

A flaw was found in the Pluggable Authentication component of MySQL. An unauthenticated remote attacker could exploit this vulnerability across multiple network protocols to cause the server to hang or crash repeatedly, resulting in a Denial of Service (DoS). In addition, successful exploitation may allow unauthorized modification, insertion, or deletion of accessible database records.

Отчет

This vulnerability is rated as having a Moderate impact because exploitation requires satisfying complex attack conditions despite being remotely accessible without prior authentication. Under standard Red Hat Enterprise Linux deployments, database instances are typically shielded behind internal networks or firewalls, further limiting exposure to untrusted network traffic. While a successful exploit could trigger service instability or partial record manipulation, confidentiality remains unaffected and exploitation cannot be executed trivially.
