Attack-Flow Graph

Executive Summary

This is a denial-of-service (DoS) vulnerability in MySQL Server and MySQL Cluster versions 9.7.0 to 9.7.1. It involves the JSON Duality component and allows a high-privileged attacker with network access to cause the server to hang or crash repeatedly by exploiting improper handling of JSON operations.

Detection Guidance

This vulnerability affects MySQL Server and MySQL Cluster versions 9.7.0 to 9.7.1. To detect it, check the installed version of MySQL Server or MySQL Cluster on your system using commands like 'mysql --version' or 'mysql-cluster --version'. Compare the output with the affected versions listed.

Impact Analysis

If you use MySQL Server or MySQL Cluster versions 9.7.0-9.7.1, an attacker could exploit this flaw to disrupt database availability, leading to service outages or degraded performance. This could affect applications relying on the database for critical operations.

Compliance Impact

This vulnerability primarily impacts availability, which could lead to data processing delays or interruptions. While not directly violating GDPR or HIPAA, repeated outages may affect compliance with requirements for timely data access or processing, depending on specific use cases.

Mitigation Strategies

Upgrade MySQL Server and MySQL Cluster to a version beyond 9.7.1 immediately. If upgrading is not possible, restrict network access to the MySQL service and ensure only trusted users have high privileges. Monitor for unusual activity or crashes in the MySQL service.
