MySQL 8.0.x < 8.0.27 Multiple Vulnerabilities (Oct 2021 CPU)

critical Nessus Plugin ID 154258
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote database server is affected by multiple vulnerabilities.


The version of MySQL running on the remote host is 8.0.x prior to 8.0.27. It is, therefore, affected by multiple vulnerabilities, including the following, as noted in the October 2021 Critical Patch Update advisory:

- A vulnerability in the OpenSSL component that can result in a takeover of the MySQL server.

- An easily exploitable vulnerability in the Kerberos component of MySQL server that allows an unauthenticated, remote attacker to affect availability. (CVE-2021-36222)

- An easily exploitable vulnerability in the cURL component that allows an unauthenticated, remote attacker to affect the availability of the MySQL Server. (CVE-2021-22926)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to MySQL version 8.0.27 or later.
