Описание

Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Group Replication GCS). 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 MySQL. An authenticated, remote attacker with high privileges could cause a complete Denial of Service (DoS) by exploiting a vulnerability in the Group Replication component over the network. Successful exploitation causes the server or cluster to hang or crash repeatedly, disrupting database availability.

Отчет

This vulnerability is rated as having a Moderate impact for Red Hat Enterprise Linux environments because exploiting it requires high-level administrative privileges over the network and only affects system availability without compromising confidentiality or integrity. In standard Red Hat deployments, Group Replication is not enabled by default, significantly limiting the exposed attack surface unless high-availability clustering has been explicitly configured. Consequently, the issue is restricted to systems utilizing this optional replication topology and cannot be leveraged by unauthenticated or low-privileged users.
