"The version of MySQL running on the remote host is 8.0.x prior to 8.0.22. It is, therefore, affected by multiple
vulnerabilities, including the following, as noted in the October 2020 Critical Patch Update advisory:

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Security: LDAP Auth). 
  Supported versions that are affected are 8.0.21 and prior. Easily exploitable vulnerability allows 
  low privileged attacker with access to the physical communication segment attached to the hardware 
  where the MySQL Server executes to compromise MySQL Server. Successful attacks of this vulnerability 
  can result in takeover of MySQL Server (CVE-2020-14878).

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions
  that are affected are 8.0.21 and prior. Easily exploitable vulnerability allows high privileged attacker 
  with network access via multiple protocols to compromise MySQL Server. Successful attacks of this 
  vulnerability can result in takeover of MySQL Server (CVE-2020-14828)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that
  are affected are 5.7.31 and prior and 8.0.21 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-2020-14775). 

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