Description

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.14. Difficult to exploit 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 access to critical data or complete access to all Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:N/A:N).

  "executiveSummary": "A vulnerability has been identified within the Core component of Oracle VM VirtualBox version 7.2.14, affecting the Oracle Virtualization product family. This security flaw is categorized as a difficult-to-exploit vulnerability that requires specific conditions for successful execution. The primary risk associated with this security issue is the potential compromise of the Oracle VM VirtualBox application by a locally authenticated threat actor possessing high privileges.\nAlthough the vulnerable code resides directly inside Oracle VM VirtualBox, a successful exploit exhibits a scope change (S:C), meaning the resultant security impact extends significantly beyond the boundaries of the virtualized environment to affect additional underlying or adjacent infrastructure components.\nThe exploitation of this vulnerability directly impacts data confidentiality, leading to unauthorized access to critical data or complete access to all data accessible via Oracle VM VirtualBox. It does not, however, impact data integrity or system availability. According to the CVSS 3.1 scoring metrics, the vulnerability receives a Base Score of 5.3 with the vector string CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:N/A:N. This highlights that the attack vector is strictly local, the attack complexity is high, high privileges are required for initiation, and no user interaction is necessary.\nOrganizations running the affected Oracle VM VirtualBox version face potential confidentiality breaches if local administrative controls are bypassed or compromised, necessitating strict adherence to hardening guidelines and prompt vendor patch application.",
  "technicalDetails": "The vulnerability resides in the Core component of Oracle VM VirtualBox version 7.2.14. The attack vector is localized (AV:L), requiring the adversary to have physical or remote interactive logon access to the underlying operating system infrastructure where the hypervisor and Oracle VM VirtualBox processes execute.\nExploitation complexity is classified as high (AC:H), indicating that successful execution requires specific race conditions, precise memory manipulation, or complex sequencing of administrative operations that are difficult to replicate reliably.\nFurthermore, the attacker must already possess high privileges (PR:H), such as root or Administrator level access on the host operating system, to interact with the privileged components or APIs exposed by the Core module of Oracle VM VirtualBox. No user interaction (UI:N) is required from other operators during the attack lifecycle.\nThe attack flow proceeds as follows: First, the high-privileged local attacker establishes an authenticated interactive session on the host infrastructure executing Oracle VM VirtualBox. Second, leveraging their elevated host privileges, the attacker interacts with the vulnerable Core component of Oracle VM VirtualBox. Third, by overcoming the high attack complexity—potentially exploiting flaws in inter-process communication, shared memory regions, or hypervisor management interfaces—the attacker induces an unexpected state in the core virtualization engine.\nDue to the scope change (S:C) characteristic of this vulnerability, the exploit breaks the security boundaries of the target component, allowing the adversary to cross isolation barriers. In the post-exploitation phase, this boundary traversal grants the attacker unauthorized access to sensitive data structures, configuration secrets, or complete access to all data repositories accessible to Oracle VM VirtualBox.\nThe impact is strictly restricted to confidentiality (C:H) with no direct capabilities for integrity modification (I:N) or denial of service availability disruption (A:N)."
