MySQL vulnerability analysis and mitigation

CVE-2021-2370 is a security vulnerability affecting MySQL Server versions 8.0.25 and prior. This vulnerability was disclosed as part of Oracle's July 2021 Critical Patch Update (Oracle CPU). The vulnerability allows high privileged attackers with network access to compromise MySQL Server through multiple protocols (NVD).

The vulnerability has been assigned a CVSS v3.1 base score of 4.9 (Medium), with the following vector: AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H. This indicates that the vulnerability requires network access and high privileges to exploit, but does not require user interaction. The impact primarily affects system availability, with no direct impact on confidentiality or integrity (Oracle CPU).

Successful exploitation of this vulnerability could allow an attacker to cause a denial of service (DoS) condition affecting the availability of MySQL Server. The vulnerability requires high privileges to exploit, limiting its potential impact to authenticated users with elevated access (NetApp Advisory).

Oracle has released patches to address this vulnerability in MySQL version 8.0.26. Users are strongly recommended to upgrade to this version or later to mitigate the risk. The fix is available through Oracle's Critical Patch Update from July 2021 (Oracle CPU).
