Attack-Flow Graph

Executive Summary

This is a denial-of-service vulnerability in MySQL Server and MySQL Cluster versions 9.7.0 to 9.7.1. It allows a low-privileged attacker with network access to cause the server or cluster to hang or crash repeatedly by exploiting the GIS component.

Detection Guidance

Detecting this vulnerability requires checking the installed version of MySQL Server or MySQL Cluster. Compare your version against the affected versions (9.7.0 to 9.7.1). Use commands like 'mysql --version' or check package managers (e.g., 'dpkg -l | grep mysql-server' for Debian-based systems). If vulnerable, update immediately.

Impact Analysis

If you use MySQL Server or MySQL Cluster versions 9.7.0-9.7.1, an attacker could disrupt database operations by making the system unavailable. This could lead to downtime, data unavailability, and potential loss of service for applications relying on the database.

Compliance Impact

This vulnerability could impact compliance by causing unplanned downtime, leading to violations of availability requirements in GDPR (data protection) and HIPAA (healthcare data). Unavailability of critical data may result in non-compliance with service level agreements and regulatory obligations.

Mitigation Strategies

Upgrade MySQL Server and MySQL Cluster to versions later than 9.7.1 to address the vulnerability. Apply the latest patches from Oracle as soon as possible.
