Attack-Flow Graph

Executive Summary

This is a denial-of-service (DoS) vulnerability in MySQL Server and MySQL Cluster. It allows a high-privileged attacker with network access to cause the server or cluster to hang or crash repeatedly by exploiting issues in client programs. The attack requires significant access and is not easy to execute.

Impact Analysis

If exploited, this vulnerability could disrupt database operations by making the MySQL Server or Cluster unavailable. This leads to downtime, loss of service, and potential data access issues for applications relying on these databases.

Compliance Impact

This vulnerability could impact compliance by causing unplanned downtime, leading to violations of availability requirements in GDPR or HIPAA. Unauthorized disruptions may also affect data integrity and access controls.

Mitigation Strategies

Upgrade MySQL Server and MySQL Cluster to versions beyond the affected ranges (8.4.12+, 9.7.3+, 26.7.1+ for Server; 8.0.49+, 8.4.12+, 9.7.3+, 26.7.1+ for Cluster). Apply the latest patches from Oracle to address the vulnerability.
