Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Audit Log). Supported versions that are affected are 5.7.26 and prior and 8.0.16 and prior. Difficult to exploit 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. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H).

An update of the mysql package has been released.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4070-1 advisory.

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

    Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 19.04 have been updated to MySQL 5.7.27.

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

    Please see the following for more information:

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

Oracle reports :

This Critical Patch Update contains 45 new security fixes for Oracle MySQL. 4 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

The version of MySQL running on the remote host is 8.0.x prior to 8.0.17. It is, therefore, affected by multiple vulnerabilities, including three of the top vulnerabilities below, as noted in the July 2019 and October 2022 Critical Patch Update advisories:

  - An unspecified vulnerability in the     'Shell: Admin / InnoDB Cluster' subcomponent could allow     an unauthenticated attacker to takeover an affected MySQL     Server. A successful attack requires user interaction.
    (CVE-2019-2822)

  - As unspecified vulnerability in the 'Server: Replication'     subcomponent could allow an unauthenticated attacker to     cause the server to hang or to, via a frequently     repeatable crash, cause a complete denial of service.
    Additionally, a successful attacker could perform     unauthorized modifications to some MySQL Server     accessible data. (CVE-2019-2800)

  - As unspecified vulnerability in the 'Server: Charsets'     subcomponent could allow an unauthenticated attacker to     cause the server to hang or to, via a frequently     repeatable crash, cause a complete denial of service.
    (CVE-2019-2795)

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 5.7.x prior to 5.7.27. It is, therefore, affected by multiple vulnerabilities, including three of the top vulnerabilities below, as noted in the July 2019 Critical Patch Update advisory:

  - A stack-based buffer overflow vulnerability in the     'Server: Packaging (cURL)' subcomponent could allow an     unauthenticated attacker to gain complete control of an     affected instance of MySQL Server. (CVE-2019-3822)

  - A vulnerability in the 'Server: Parser' subcomponent.
    This is an easily exploitable vulnerability that allows     a low privileged attacker with network access via     multiple protocols to compromise the server. Successful     attacks involving this vulnerability can result in the     unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS). (CVE-2019-2805)

  - A vulnerability in the 'Server: XML' subcomponent. This     is an easily exploitable vulnerability that allows a     low privileged attacker with network access via multiple     protocols to compromise a server.Successful attacks     involving this vulnerability can result in the     unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS).
    (CVE-2019-2740)

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