CVE-2022-21571: 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 6.1.36. 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 (scope change). 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-2022-21571 is a high-severity Oracle VM VirtualBox Core flaw affecting supported versions before 6.1.36. A highly privileged local attacker on the infrastructure running VirtualBox could take over VirtualBox, with possible impact beyond the virtualization product itself.

Executive priority

Treat this as a high-priority patching item for hosts running VirtualBox, especially shared administrative, development, or build infrastructure. The prerequisite is high local privilege, which lowers broad internet risk but still matters after credential compromise.

Technical view

The vulnerability is local, low-complexity, requires high privileges, and needs no user interaction. Oracle scores it CVSS 8.2 with scope changed and high confidentiality, integrity, and availability impact. The source bundle identifies Oracle VM VirtualBox prior to 6.1.36 as affected.

Likely exposure

Exposure is most likely on developer workstations, lab systems, build hosts, or servers where Oracle VM VirtualBox is installed and privileged users can log on locally.

Exploitation context

The provided sources do not show active exploitation, and the CVE is not marked CISA KEV. Risk depends on whether an attacker already has high-privilege local access to a VirtualBox host.

Researcher notes

Key constraints are local attack vector and high privileges. The notable risk signal is scope change with full CIA impact, indicating compromise may extend beyond the immediate VirtualBox component. No source in the bundle confirms public exploitation.

Mitigation direction

  • Upgrade Oracle VM VirtualBox to 6.1.36 or later where applicable.
  • Apply Oracle July 2022 Critical Patch Update guidance for VirtualBox.
  • For Gentoo systems, follow GLSA-202208-36 package update guidance.
  • Restrict privileged logon access to systems running VirtualBox.
  • Check vendor advisories for any environment-specific hardening guidance.

Validation and detection

  • Inventory systems with Oracle VM VirtualBox installed.
  • Confirm installed VirtualBox versions are not prior to 6.1.36.
  • Review privileged local access to VirtualBox hosts.
  • Verify patch status against Oracle CPU July 2022 guidance.
  • Check Gentoo package status where Gentoo systems are in scope.
