Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues 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 8.0.23. It is, therefore, affected by multiple vulnerabilities, including the following, as noted in the January 2021 Critical Patch Update advisory:

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Stored Procedure). Supported   versions that are affected are 8.0.22 and prior. Easily exploitable vulnerability allows high privileged   attacker with network access via multiple protocols to compromise MySQL Server. While the vulnerability is in MySQL   Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can   result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2021-2046)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions   that are affected are 8.0.22 and prior. Easily exploitable vulnerability allows low privileged attacker with   network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can   result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2021-2024)

  - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are   affected are 5.7.32 and prior and 8.0.22 and prior. Difficult to exploit vulnerability allows unauthenticated   attacker with network access via multiple protocols to compromise MySQL Client. Successful attacks of this   vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of   MySQL Client. (CVE-2021-2011)

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