MySQL vulnerability analysis and mitigation

Overview

CVE-2020-2761 is a security vulnerability affecting the Server: Security: Privileges component of Oracle MySQL Server versions 8.0.18 and prior. The vulnerability was disclosed and patched as part of Oracle's April 2020 Critical Patch Update (Oracle CPU).

Technical details

The vulnerability has been assigned a CVSS v3.0 base score of 4.9 (MEDIUM), with the following vector: CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H. This indicates that the vulnerability requires high privileges to exploit, can be attacked over the network, has low attack complexity, requires no user interaction, and could potentially impact system availability (Oracle CPU).

Impact

A successful exploitation of this vulnerability could allow an attacker with high privileges to cause a denial of service condition affecting the availability of MySQL Server (Oracle CPU, NetApp Advisory).

Mitigation and workarounds

Oracle has released patches to address this vulnerability in MySQL version 8.0.19. Users are strongly recommended to upgrade to this version or later. Until patches can be applied, limiting network access and restricting privileged user access can help reduce the risk (Oracle CPU, NetApp Advisory).
