The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.48 and prior, 5.7.30 and prior and 8.0.20 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-2020-14539)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of MySQL running on the remote host is 5.6.x prior to and including 5.6.48. It is, therefore, affected by multiple vulnerabilities, including the following, as noted in the July 2020 Critical Patch Update advisory:

  -  A vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions   that are affected are 5.6.48 and prior, 5.7.30 and prior and 8.0.20 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-2020-14539)

  - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are   affected are 5.6.48 and prior, 5.7.30 and prior and 8.0.20 and prior. Difficult to exploit vulnerability allows   low privileged 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-2020-14550)

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/C++ (OpenSSL)).
  Supported versions that are affected are 8.0.20 and prior. Easily exploitable vulnerability allows unauthenticated   attacker with network access via TLS to compromise MySQL Connectors. Successful attacks of this vulnerability can   result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL   Connectors. (CVE-2020-1967)

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

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3732 advisory.

    MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld)     and many client programs and libraries.

    The following packages have been upgraded to a later upstream version: mysql (8.0.21).

The remote host is affected by the vulnerability described in GLSA-202105-27 (MySQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in MySQL. Please review       the CVE identifiers referenced below for details.
  Impact :

    An attacker could possibly execute arbitrary code with the privileges of       the process, escalate privileges, gain access to critical data or       complete access to all MySQL server accessible data, or cause a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

The version of MySQL running on the remote host is 5.7.x prior to and including 5.7.30. It is, therefore, affected by multiple vulnerabilities, as noted in the July 2020 Critical Patch Update advisory:

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions   that are affected are 5.7.30 and prior and 8.0.17 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 unauthorized ability to cause a hang or frequently repeatable crash (complete   DOS) of MySQL Server. (CVE-2021-2160)

  - A vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions   that are affected are 5.6.48 and prior, 5.7.30 and prior and 8.0.20 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-2020-14539)

 - A vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are   affected are 5.6.48 and prior, 5.7.30 and prior and 8.0.20 and prior. Difficult to exploit vulnerability allows   low privileged 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-2020-14550)
