CVE-2023-22114 - Vulnerability in MySQL Server InnoDB Component Leads to Denial of Service

The MySQL Server product of Oracle MySQL, specifically the InnoDB component, has been found to have a significant vulnerability that could be easily exploited by a high privileged attacker with network access. The supported versions affected by this vulnerability include versions 8..34 and prior, as well as version 8.1.. Successful exploitation can result in unauthorized ability to cause a hang or frequently repeatable crash, leading to a complete denial of service (DoS) situation for MySQL Server. The CVSS 3.1 Base Score for this vulnerability stands at 4.9, with the primary impact on the availability of the server. The CVSS Vector is defined as (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

Code Snippet

While the details of the affected code are not publicly disclosed, it's crucial for organizations to apply patches and take the necessary steps to secure their databases. Regularly reviewing and updating your MySQL Server installation, coupled with following industry best practices for security, can mitigate the risks associated with this vulnerability.

It's essential to apply any available patches or updates from Oracle to address this vulnerability. For information on the latest patches and updates, visit the Oracle Critical Patch Update Advisory here and the MySQL Release Notes here.

Exploit Details

This vulnerability allows a high privileged attacker with network access via multiple protocols to exploit the InnoDB component of MySQL Server. It particularly affects the 8..34 and prior versions and the 8.1. version of the software. A successful attack would enable the attacker to compromise the MySQL Server and cause a complete denial of service situation.

To exploit this vulnerability, an attacker would need to have a high level of privilege, which might be obtained through techniques such as social engineering, or by exploiting other vulnerabilities within the system. Once the attacker gains access, they could perform actions that would cause the server to crash or hang, disrupting the normal operation of the system.

The impact of this vulnerability is significant, as a successful exploit could lead to a complete DoS situation for the MySQL Server. This would disrupt the normal operation of any applications or services that rely on the affected MySQL Server, potentially causing significant downtime and loss of critical data.

Prevention and Mitigation

To protect against this vulnerability, it's crucial to ensure that your MySQL Server installation is up-to-date and has the appropriate patches applied. Regularly review and update your MySQL Server installation, following industry best practices for security. You should also employ strong access controls, ensuring only authorized users have access to sensitive systems.

Make sure to monitor your environment for any signs of unauthorized access or unusual activity. Implementing robust logging and monitoring solutions can help detect and prevent potential exploitation attempts.
