Attack-Flow Graph

Executive Summary

This is a denial-of-service (DoS) vulnerability in MySQL Server and MySQL Cluster. It allows an unauthenticated attacker with local system access to crash the database service repeatedly, causing prolonged downtime.

Detection Guidance

This vulnerability affects MySQL Server and MySQL Cluster versions 8.4.0-8.4.10, 9.7.0-9.7.1, and 8.0.0-8.0.47. Detection requires checking installed versions against these ranges. Use commands like 'mysql --version' or 'mysqld --version' to identify the running version. If affected versions are found, apply the latest patches from Oracle immediately.

Impact Analysis

If exploited, it can disrupt database operations, leading to service unavailability, data access issues, and potential business disruptions for applications relying on MySQL.

Compliance Impact

This vulnerability causes denial-of-service (DoS) conditions in MySQL Server or Cluster, leading to system unavailability. Such disruptions may violate compliance requirements in GDPR (availability of personal data processing systems) and HIPAA (access to protected health information systems). Unauthorized downtime could result in non-compliance with availability and integrity controls.

Mitigation Strategies

Upgrade MySQL Server and MySQL Cluster to versions 8.4.11 or later, or 9.7.2 or later, as these versions address the vulnerability. Apply the latest patches from Oracle immediately to prevent potential denial-of-service attacks.
