Oracle reports :

This Critical Patch Update contains 31 new security fixes for Oracle MySQL. 6 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

An update of the mysql package has been released.

The version of MySQL running on the remote host is 5.7.x prior to 5.7.28. It is, therefore, affected by multiple vulnerabilities, including three of the top vulnerabilities below, as noted in the October 2019 Critical Patch Update advisory:

  - Vulnerabilities in the MySQL Server product of Oracle MySQL (component: Server: Optimizer and PS). Easily   exploitable vulnerabilities which allow low privileged attackers with network access via multiple protocols to   compromise MySQL Server. Successful exploitation of these vulnerabilities can result in unauthorized ability to cause   a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2946, CVE-2019-2974)

  - A non-privileged user or program can put code and a config file in a known non-privileged path (under   C:/usr/local/) that will make curl <= 7.65.1 automatically run the code (as an openssl 'engine') on invocation.
  If that curl is invoked by a privileged user it can do anything it wants. (CVE-2019-5443)

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

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The version of MySQL running on the remote host is 5.6.x prior to 5.6.46. It is, therefore, affected by multiple vulnerabilities, including three of the top vulnerabilities below, as noted in the October 2019 Critical Patch Update advisory:
  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). 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-2019-2794)

  - Vulnerabilities in the MySQL Server product of Oracle MySQL (component: Server: Security: Encryption). Easily   exploitable vulnerabilities allow unauthenticated attackers with network access via multiple protocols to compromise   MySQL Server. Successful exploitation of these vulnerabilities can result in unauthorized read access to a subset of   MySQL Server accessible data. (CVE-2019-2923, CVE-2019-2924)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4195-1 advisory.

    Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to     fix these issues.

    MySQL has been updated to 8.0.18 in Ubuntu 19.10. Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 19.04     have been updated to MySQL 5.7.28.

    In addition to security fixes, the updated packages contain bug fixes, new features, and possibly     incompatible changes.
