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 · moderate confidence

This is a local privilege escalation vulnerability in McAfee Endpoint Security (ENS) where a local user can bypass security protections by using a carefully crafted input file. The vulnerability exists in versions prior to the February 2020 update (10.7.0), allowing local users to circumvent local security controls.

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. Verify McAfee Endpoint Security installation and version
    Open the McAfee Endpoint Security client UI, or use the command 'Get-ItemProperty HKLM:\SOFTWARE\McAfee\Endpoint_Security' in PowerShell to read the ProductVersion registry value
    Affected if The ProductVersion is 10.5.0, 10.5.1, 10.5.2, 10.5.3, 10.5.4, 10.5.5, or 10.6.0
  2. Confirm version is prior to February 2020 update
    Check the installed build or version detail - affected versions lack the February 2020 update that patches this vulnerability
    Affected if The installed version is 10.6.0 or earlier without the February 2020 patch applied
  3. Identify local user presence
    Review local user accounts on the system using 'Get-LocalUser' in PowerShell or check if non-administrator local accounts exist
    Affected if Local non-administrative user accounts exist on the endpoint, as the privilege escalation targets local users

The environment is affected if McAfee Endpoint Security is installed with a version between 10.5.0 and 10.6.0 inclusive, prior to the February 2020 10.7.0 update, and the system has local user accounts.
