CVE-2025-62587 Overview
CVE-2025-62587 is a high-severity vulnerability in the Core component of Oracle VM VirtualBox. Oracle disclosed the flaw in the October 2025 Critical Patch Update. The affected versions are 7.1.12 and 7.2.2.
A high-privileged attacker with logon access to the host running Oracle VM VirtualBox can compromise the hypervisor. The vulnerability carries a scope change, meaning successful exploitation impacts resources beyond the vulnerable component. The weakness is categorized under [CWE-267: Privilege Defined With Unsafe Actions].
Critical Impact
Successful exploitation results in full takeover of Oracle VM VirtualBox with confidentiality, integrity, and availability impact on adjacent guest workloads.
Affected Products
- Oracle VM VirtualBox 7.1.12
- Oracle VM VirtualBox 7.2.2
- Oracle Virtualization (Core component)

Technical Details for CVE-2025-62587
Vulnerability Analysis
The vulnerability resides in the Core component of Oracle VM VirtualBox, the module that mediates virtualization primitives between guest virtual machines and the host operating system. An attacker who already holds high privileges on the host can invoke unsafe privileged actions exposed by the hypervisor.
Exploitation results in takeover of the VirtualBox instance. The scope change indicator reflects that a compromise of the hypervisor extends to guest virtual machines running on the host. Confidentiality, integrity, and availability of hosted workloads can be affected.
Oracle rates the attack complexity as low, meaning no specialized conditions must be met once the attacker has host logon access. User interaction is not required.
Root Cause
The underlying weakness maps to [CWE-267], a privilege defined with unsafe actions. A privileged operation exposed by the Core component permits an authenticated actor to perform actions that should be restricted or gated by additional integrity checks. Oracle has not published the specific unsafe primitive, and no public proof-of-concept is available.
Attack Vector
The attack vector is local. An attacker must first authenticate to the host running Oracle VM VirtualBox with high privileges. From that position, the attacker invokes the vulnerable hypervisor pathway to escape the guest boundary or seize control of the VirtualBox process. The EPSS score is 0.188%, reflecting no observed in-the-wild exploitation, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
No verified proof-of-concept code is available. Refer to the Oracle Critical Patch Update Advisory for authoritative technical details.
Detection Methods for CVE-2025-62587
Indicators of Compromise
- Unexpected restarts or crashes of the VBoxHeadless, VBoxManage, or VirtualBox processes on the host
- Creation of new privileged local accounts or unexpected sudo/administrator activity preceding hypervisor manipulation
- Anomalous guest-to-host file system access or unexpected shared folder modifications
Detection Strategies
- Audit host operating system logs for high-privileged user sessions that invoke VirtualBox management binaries outside of maintenance windows
- Monitor for unauthorized modifications to VirtualBox configuration files (.vbox, VBoxSVC state) on hypervisor hosts
- Correlate privileged local logons with subsequent VirtualBox API or CLI activity to identify unusual administrative sequences
Monitoring Recommendations
- Enable command-line auditing on hosts running VirtualBox and forward events to a centralized log platform
- Track VirtualBox process behavior including child process creation and unexpected library loads
- Alert on privilege escalation attempts and use of local administrator credentials against virtualization hosts
How to Mitigate CVE-2025-62587
Immediate Actions Required
- Apply the October 2025 Oracle Critical Patch Update to all Oracle VM VirtualBox installations running versions 7.1.12 or 7.2.2
- Inventory hosts running affected VirtualBox versions and prioritize patching on systems hosting production or sensitive guest workloads
- Restrict interactive logon on VirtualBox hosts to a minimum set of administrators and enforce multi-factor authentication
Patch Information
Oracle released fixes as part of the October 2025 Critical Patch Update. Administrators should review the Oracle Critical Patch Update Advisory and upgrade to the patched VirtualBox release identified for their platform. There is no vendor-supplied workaround.
Workarounds
- Remove or disable Oracle VM VirtualBox on hosts where it is not required until patches are applied
- Reduce the number of accounts with high privileges on hypervisor hosts and monitor those accounts for anomalous activity
- Isolate VirtualBox hosts on management network segments with strict access controls limiting who can reach the host
# Verify installed VirtualBox version on the host
VBoxManage --version
# Linux example: list local accounts with sudo or wheel privileges for review
getent group sudo wheel
# Windows example: enumerate local Administrators group
net localgroup Administrators
