Description
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.14. 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 unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox. CVSS 3.1 Base Score 6.0 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H).

Impact

The vulnerability in Oracle VM VirtualBox 7.2.14 results from an improper authorization check that allows a high‑privileged attacker logged onto the host to cause the VirtualBox process to hang or crash. Because the CVSS vector indicates a changed scope (S:C), the flaw can affect additional components beyond VirtualBox, potentially impacting the host operating system or other services running in the same environment. This leads to a complete denial of service for virtual machine operations and management.

Affected Systems

Oracle Corporation's VirtualBox product, specifically version 7.2.14, is impacted. Systems running this version on host infrastructure are at risk. Any environment that relies on VirtualBox for running virtual machines should verify their appliance version.

Risk and Exploitability

The CVSS 3.1 Base Score of 6.0 shows a moderate severity, with a local attack (AV:L), low complexity (AC:L), high privilege requirement (PR:H), and a changed scope. The EPSS score of < 1% indicates a very low exploitation probability, and the vulnerability is not listed in CISA’s KEV catalog. Due to the scope change, an attacker can cause a denial of service that may extend to other components on the host, but the vulnerability does not enable remote code execution or data exfiltration. The risk remains moderate and warrants timely remediation.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the Oracle VirtualBox patch that corrects the improper authorization (CWE‑284) flaw.
  • Enforce strict access controls on the host to prevent high‑privileged users from executing the vulnerability.
  • Configure monitoring to detect VirtualBox hangs or crashes and implement automatic restart or fail‑over for critical VMs.
