Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported versions that are affected are Prior to 7.0.24 and prior to 7.1.6. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Oracle VM VirtualBox contains a vulnerability in its Core component that allows a low-privileged attacker with local access to the infrastructure to gain unauthorized high confidentiality access to data accessible by VirtualBox. The vulnerability affects versions prior to 7.0.24 and 7.1.6. Exploitation is local (AV:L), low complexity, and requires no user interaction.

MitigationUpgrade Oracle VM VirtualBox to version 7.0.24, 7.1.6, or later to remediate this vulnerability. In enterprise environments, validate the upgrade in a staging environment before production deployment.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify VirtualBox installation
    Run 'vboxmanage --version' on the command line. On Windows, you can also check Programs and Features or the VirtualBox application Help > About. On Linux, check the package manager (dpkg -l | grep virtualbox or rpm -qa | grep VirtualBox).
    Affected if VirtualBox is installed and the version is shown
  2. Compare installed version against affected ranges
    Check if the version output from step 1 falls within 7.0.0 to 7.0.23, or 7.1.0 to 7.1.5. These are the vulnerable version ranges.
    Affected if Version is 7.0.x where x is less than 24, or 7.1.x where x is less than 6
  3. Verify VirtualBox is running or configured
    Run 'vboxmanage list vms' to see if any virtual machines are configured, or check if the VirtualBox service is active. This indicates VirtualBox is in use.
    Affected if VirtualBox is actively configured or running on the system
  4. Assess local access exposure
    Determine if untrusted local users have access to the VirtualBox host system. The vulnerability requires local access to the infrastructure.
    Affected if Untrusted users can log into the host machine where VirtualBox is installed

You are affected if VirtualBox version is 7.0.0 through 7.0.23 or 7.1.0 through 7.1.5, and untrusted local users can access the host system.

Interim mitigation

Upgrade Oracle VM VirtualBox to version 7.0.24, 7.1.6, or later to remediate this vulnerability. In enterprise environments, validate the upgrade in a staging environment before production deployment.

Recommended fix High confidence

7.0.24 or 7.1.6 (whichever is the latest in your minor release line)

  1. 1. Check current VirtualBox version by opening VirtualBox and going to Help > About, or running 'vboxmanage --version'
  2. 2. Download the appropriate fixed version (7.0.24 or 7.1.6) from the official Oracle website: https://www.virtualbox.org/wiki/Downloads
  3. 3. Ensure all virtual machines are powered off and backed up if necessary
  4. 4. Install the new version, overwriting the existing installation
  5. 5. After installation, verify the version matches the fixed release (7.0.24 or 7.1.6)
Caveat Minor version upgrades typically preserve VM configurations; however, always backup VM images before upgrading
