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

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.
    (CVE-2021-3711)

  - 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.
