Executive Summary

This vulnerability exists in the MySQL Server product of Oracle MySQL, specifically in the Server: Information Schema component. It affects supported versions 8.0.0-8.0.45, 8.4.0-8.4.8, and 9.0.0-9.6.0.

The vulnerability is easily exploitable by a high privileged attacker who has network access through multiple protocols. Successful exploitation can lead to unauthorized read access to a subset of data accessible by the MySQL Server.

The CVSS 3.1 base score is 2.7, indicating a low severity impact focused on confidentiality.

Impact Analysis

If exploited, this vulnerability can allow a high privileged attacker with network access to gain unauthorized read access to some data within the MySQL Server.

This means sensitive or confidential information stored in the affected MySQL Server versions could be exposed without authorization.

However, the impact is limited to confidentiality only, with no impact on integrity or availability.

Mitigation Strategies

To mitigate this vulnerability, Oracle strongly advises customers to apply the latest Critical Patch Update patches immediately.

These patches are cumulative and include security fixes for MySQL Server among many other Oracle products.

Remaining on actively supported versions and promptly installing the provided patches will help prevent exploitation of this vulnerability.

Compliance Impact

This vulnerability allows unauthorized read access to a subset of MySQL Server accessible data by a high privileged attacker with network access.

Such unauthorized data access could potentially impact compliance with data protection regulations like GDPR and HIPAA, which require protection of sensitive and personal data from unauthorized disclosure.

However, the CVE description does not provide specific details on the types of data affected or the extent of the impact on compliance.
