Welcome to our dedicated page on a recent critical security issue discovered in the MySQL database software, specifically within the 'Server: X Plugin' component of Oracle MySQL. This vulnerability is identified as CVE-2024-21196 and here, at LinuxPatch, our goal is to help you understand what this means for you and how to address this vulnerability effectively.
CVE-2024-21196 has been classified with a severity rating of 'MEDIUM' and a CVSS score of 6.5. This particular security flaw is noteworthy due to its potential impact on the availability of MySQL Server, facilitating conditions for a Denial of Service (DoS) attack. The affected versions include 8.0.39 and prior, 8.4.2 and prior, and 9.0.1 and prior. It is important to note that this vulnerability allows even a low privileged attacker, who has network access via multiple protocols, to compromise the MySQL Server.
MySQL is an immensely popular open-source relational database management system. As a staple in software stacks for many web applications, MySQL is known for its reliability, robustness, and flexibility, making it a preferred choice for both small development projects and large-scale enterprise applications. The component under threat, the Server: X Plugin, enhances MySQL's capabilities by enabling document store operations through X Protocol, adding another layer of functionality on top of the traditional SQL support.
The identified vulnerability within the Server: X Plugin can be exploited to cause a hang or repeatable crash of the MySQL Server, leading to a complete Denial of Service. This kind of threat is particularly dangerous because it affects the database's availability, potentially leading to significant downtime and disruption of services. According to the official CVE details, the attack can be mounted with low effort from an attacker with low privileges, and it does not require any user interaction, which underscores the critical nature of this vulnerability.
To mitigate the risks associated with CVE-2024-21196, it is crucial to update your MySQL Server installations to the latest version that has addressed this vulnerability. Patching the affected systems promptly is essential in preventing potential exploits.
