Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is Prior to 6.1.16. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 6.0 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a local privilege escalation vulnerability in Oracle VM VirtualBox's Core component affecting versions prior to 6.1.16. A high-privileged attacker with local access to the infrastructure where VirtualBox executes can gain unauthorized access to sensitive data due to improper access controls in the core virtualization layer.

MitigationUpgrade Oracle VM VirtualBox to version 6.1.16 or later to remediate this vulnerability. Since the attacker requires high privileges and local access, ensure strict access controls on VirtualBox hosts and monitor for unauthorized local access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify VirtualBox installation
    Run 'vboxmanage --version' or check the installed programs list on the host system to confirm Oracle VM VirtualBox is installed
    Affected if VirtualBox is present on the system
  2. Determine installed VirtualBox version
    Execute 'vboxmanage --version' from command line, or look at the VirtualBox application version in the About/Help section of the GUI, or check the installed version via system package manager
    Affected if The version displayed is lower than 6.1.16 (for example 6.1.14, 6.0.14, 5.x.x)
  3. Assess local access exposure
    Review who has local access to the VirtualBox host system and verify the presence of high-privileged accounts that could exploit this flaw
    Affected if Untrusted or low-privileged local users have access to the VirtualBox host machine

If Oracle VM VirtualBox is installed with a version lower than 6.1.16 and untrusted high-privileged local users can access the host, the environment is affected by CVE-2020-14889.
