Attack-Flow Graph

Executive Summary

This vulnerability exists in the MySQL Server product of Oracle MySQL, specifically in the InnoDB 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.

If successfully exploited, the attacker can cause the MySQL Server to hang or crash repeatedly, resulting in a complete denial of service (DoS).

Impact Analysis

The main impact of this vulnerability is on the availability of the MySQL Server. An attacker with high privileges and network access can exploit this vulnerability to cause the server to hang or crash repeatedly.

This results in a denial of service (DoS), making the MySQL Server unavailable to legitimate users and potentially disrupting business operations that depend on the database.

Compliance Impact

The vulnerability allows a high privileged attacker to cause a denial of service (DoS) by crashing or hanging the MySQL Server, impacting availability.

However, there is no information provided about any impact on confidentiality or integrity of data, which are critical factors for compliance with standards like GDPR or HIPAA.

Therefore, based on the available information, this vulnerability primarily affects availability but does not directly indicate non-compliance with data protection regulations.
