MySQL vulnerability analysis and mitigation

A vulnerability has been identified in the MySQL Server product of Oracle MySQL, specifically in the Server: Optimizer component. The affected versions include MySQL Server 8.0.35 and prior, as well as 8.2.0 and prior. This vulnerability (CVE-2024-20970) is characterized as easily exploitable and allows high-privileged attackers with network access via multiple protocols to compromise MySQL Server (Oracle Advisory).

The vulnerability has been assigned a CVSS 3.1 Base Score of 4.9 (Medium severity), with the following vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H. The scoring indicates that while the vulnerability is network-accessible (AV:N) and requires low attack complexity (AC:L), it necessitates high privileges (PR:H) and no user interaction (UI:N). The scope is unchanged (S:U), with no impact on confidentiality (C:N) or integrity (I:N), but high impact on availability (A:H) (NVD).

Successful exploitation of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. The impact is primarily focused on system availability, with no direct effects on data confidentiality or integrity (Oracle Advisory).

Oracle has released patches to address this vulnerability in their January 2024 Critical Patch Update. Users are strongly advised to update to the latest version of MySQL Server that includes these security fixes (Oracle Advisory).
