CVE-2021-2250: Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core).

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is Prior to 6.1.20. 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 takeover of Oracle VM VirtualBox. CVSS 3.1 Base Score 8.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).

Security readout for executives and security teams

Plain-English summary

CVE-2021-2250 is a high-severity Oracle VM VirtualBox Core flaw affecting versions prior to 6.1.20. It requires a high-privileged local attacker with logon access where VirtualBox runs, but successful exploitation can result in takeover of VirtualBox and may affect related products.

Executive priority

Treat as a high-priority patching item for systems where VirtualBox is installed and local privileged access is shared or operationally sensitive. Business urgency is lower than unauthenticated remote flaws, but compromise can still affect confidentiality, integrity, and availability.

Technical view

The CVSS 3.1 score is 8.2 with local attack vector, low complexity, high privileges, no user interaction, changed scope, and high confidentiality, integrity, and availability impact. The public bundle identifies Oracle VM VirtualBox Core as affected before 6.1.20; deeper root-cause details are not included.

Likely exposure

Exposure is most likely on developer workstations, lab systems, build hosts, or servers running Oracle VM VirtualBox before 6.1.20, especially where privileged local users or administrators can log on.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The vulnerability is not described as remotely exploitable without credentials; it requires high-privileged local access to the VirtualBox infrastructure.

Researcher notes

Public metadata gives the affected component, privilege requirement, CVSS vector, and version boundary, but not detailed bug mechanics. Validation should focus on version exposure, local privilege model, and whether VirtualBox is embedded in broader workflows or products.

Mitigation direction

  • Upgrade Oracle VM VirtualBox from versions prior to 6.1.20 following vendor guidance.
  • Apply relevant OS distribution security updates, including Gentoo guidance where applicable.
  • Restrict privileged local logon access on systems running VirtualBox.
  • Isolate or retire unpatched VirtualBox hosts until updates are applied.
  • Track Oracle CPU advisories for any additional product impact.

Validation and detection

  • Inventory all systems running Oracle VM VirtualBox and record exact versions.
  • Confirm no deployed instance remains below version 6.1.20.
  • Check package manager history for applied Oracle or distribution security updates.
  • Review privileged local accounts on VirtualBox hosts.
  • Document any dependent products or workflows using VirtualBox.
