CVE-2020-7255: Privilege Escalation vulnerability  in ENS

Privilege escalation vulnerability in the administrative user interface in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2020 Update allows local users to gain elevated privileges via ENS not checking user permissions when editing configuration in the ENS client interface. Administrators can lock the ENS client interface through ePO to prevent users being able to edit the configuration.

Security readout for executives and security teams

Plain-English summary

This CVE affects McAfee Endpoint Security for Windows. A local, already-authenticated user could alter ENS client configuration through the administrative interface because permissions were not properly checked. Business impact is limited but relevant where endpoint protection settings must remain centrally controlled.

Executive priority

Treat as a routine endpoint hygiene item unless affected systems are broadly deployed or users can locally change protection settings. Prioritize updating and enforcing ePO locks during normal security maintenance.

Technical view

McAfee ENS for Windows 10.x before the 10.7.0 February 2020 Update has a local privilege escalation in the administrative UI. The issue is improper permission enforcement when editing ENS client configuration. CVSS 3.1 is 3.9 with local access, low privileges, high complexity, and user interaction required.

Likely exposure

Exposure is limited to Windows endpoints running McAfee ENS 10.x before the 10.7.0 February 2020 Update, especially where users can access editable ENS client settings.

Exploitation context

The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. Exploitation requires local access, low privileges, high attack complexity, and user interaction, which limits broad remote risk.

Researcher notes

The provided data identifies improper permission checking in the ENS administrative UI and CWE-264. Details are limited to local configuration editing impact; no exploit technique, public exploitation, or additional affected products are supported by the supplied sources.

Mitigation direction

  • Update McAfee ENS for Windows to 10.7.0 February 2020 Update or later.
  • Lock the ENS client interface through ePO to prevent local configuration edits.
  • Check current McAfee vendor guidance for any superseding remediation notes.
  • Review endpoint policies for unauthorized local changes to ENS configuration.

Validation and detection

  • Inventory Windows endpoints running McAfee ENS and identify 10.x versions below the fixed update.
  • Confirm ePO policies lock the ENS client interface for non-administrative users.
  • Review ENS configuration baselines for drift from centrally managed policy.
  • Perform controlled validation that standard users cannot edit protected ENS settings.
