MySQL 5.6.x < 5.6.44 Multiple Vulnerabilities (Apr 2019 CPU)

medium Nessus Plugin ID 124158
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.

Synopsis

The remote database server is affected by multiple vulnerabilities.

Description

The version of MySQL running on the remote host is 5.6.x prior to 5.6.44. It is, therefore, affected by multiple vulnerabilities, including three of the top vulnerabilities below, as noted in the April 2019 Critical Patch Update advisory:

- An unspecified vulnerability in the 'Server: Compiling (OpenSSL)' subcomponent could allow an unauthenticated attacker to gain complete access to all MySQL Server accessible data. (CVE-2019-1559)

- An unspecified vulnerability in the 'Server: Options' subcomponent could allow a high privileged attacker to hang or to, via a frequently repeatable crash, cause a complete denial of service. (CVE-2019-2683)

- An unspecified vulnerability in the 'Server: Security: Privileges' subcomponent could allow a high privileged attacker to hang or to, via a frequently repeatable crash, cause a complete denial of service. (CVE-2019-2627)

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

Solution

Upgrade to MySQL version 5.6.44 or later.
