CVE-2021-2282: 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 unauthenticated 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 7.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).

Security readout for executives and security teams

Plain-English summary

CVE-2021-2282 is a high-severity Oracle VM VirtualBox Core flaw affecting supported versions prior to 6.1.20. An attacker with local logon access where VirtualBox runs could compromise VirtualBox data confidentiality, potentially exposing critical data accessible to VirtualBox.

Executive priority

Treat this as a high-priority confidentiality risk where VirtualBox is used on shared or sensitive systems. It is less urgent than internet-exposed remote code execution, but local access paths can still create meaningful data exposure.

Technical view

Oracle rates this CVSS 3.1 7.1 with AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N. The flaw is local, low-complexity, requires no user interaction, and has a changed scope with high confidentiality impact. The source bundle does not identify a CWE.

Likely exposure

Exposure is most likely on workstations, build hosts, lab systems, or servers running Oracle VM VirtualBox before 6.1.20, especially where many users can log on locally or through remote desktop access.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The attack requires logon to the infrastructure where VirtualBox executes, but Oracle describes it as requiring no privileges and no user interaction once that access exists.

Researcher notes

Key limits: sources identify the affected product and version threshold, but not a CWE, root cause, or exploit details. Avoid assuming broader Oracle product impact beyond Oracle’s statement that attacks may significantly impact additional products.

Mitigation direction

  • Upgrade Oracle VM VirtualBox to 6.1.20 or later per vendor guidance.
  • Check Oracle and Gentoo advisories for platform-specific package guidance.
  • Restrict logon access to systems running VirtualBox.
  • Remove VirtualBox where it is no longer operationally required.
  • Prioritize systems handling sensitive guest data or shared administrative use.

Validation and detection

  • Inventory endpoints and servers running Oracle VM VirtualBox.
  • Confirm installed VirtualBox versions are not prior to 6.1.20.
  • Review who can log on to affected infrastructure.
  • Check package-management records for vendor advisory remediation.
  • Document any unsupported or unmanaged VirtualBox installations.
