REDHAT-BUG-2557799: Medium severity Oracle MySQL Server vulnerability
Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: JSON). 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 low 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 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

Frequently Asked Questions
Who is realistically exposed to this vulnerability?
MySQL Server and MySQL Cluster deployments running the affected supported version ranges are exposed if a low-privileged attacker can reach the service over the network using one of its supported protocols. The issue affects availability rather than confidentiality or integrity.
What level of access does an attacker need?
An attacker needs network access and low-privileged access to the affected MySQL Server or MySQL Cluster instance. No user interaction is required, and the attack complexity is rated low.
What is the likely impact of successful exploitation?
Successful exploitation can cause the affected MySQL Server or MySQL Cluster service to hang or repeatedly crash, resulting in a complete denial of service. The provided CVSS vector indicates no confidentiality or integrity impact.
Are default deployments affected?
The available information identifies affected product versions but does not state whether a default configuration is vulnerable. Exposure depends at minimum on network reachability and the attacker having low-privileged access.
