CVE-2020-7319: Improper Access Control Vulnerability in ENS for Windows

Improper Access Control vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2020 Update allows local users to access files which the user otherwise would not have access to via manipulating symbolic links to redirect McAfee file operations to an unintended file.

Security readout for executives and security teams

Plain-English summary

CVE-2020-7319 lets a local Windows user abuse McAfee Endpoint Security file handling to reach files they should not access. It is a high-severity endpoint security product flaw, but the provided sources do not show remote exploitation or confirmed active exploitation.

Executive priority

Treat as a high-priority hygiene fix for affected endpoint fleets. It is not currently evidenced as actively exploited, but it weakens a security control on Windows systems and can enable local privilege-adjacent file access impact.

Technical view

McAfee Endpoint Security for Windows before the 10.7.0 September 2020 Update has improper access control involving symbolic link manipulation. A local low-privileged user can redirect McAfee file operations to unintended files, affecting confidentiality, integrity, and availability under CVSS 3.1 score 8.8.

Likely exposure

Exposure is limited to Windows endpoints running McAfee Endpoint Security 10.7.x before the September 2020 update, especially systems where untrusted or lower-privileged local users can log in.

Exploitation context

The CVE requires local access and low privileges, with no user interaction. The source bundle marks KEV as false and provides no cited evidence of active exploitation in the wild.

Researcher notes

This is CWE-59, symbolic link following before file access control is correctly enforced. Scope is local and product-specific. The provided evidence does not include proof-of-concept details, exploitation telemetry, or affected CPE data.

Mitigation direction

  • Upgrade McAfee Endpoint Security for Windows to 10.7.0 September 2020 Update or later.
  • Review McAfee SB10327 for vendor-specific remediation and any superseding guidance.
  • Prioritize shared workstations, jump hosts, and systems with many local users.
  • Reduce unnecessary local interactive access until affected endpoints are updated.

Validation and detection

  • Inventory Windows endpoints running McAfee Endpoint Security.
  • Identify ENS 10.7.x installations predating the September 2020 update.
  • Confirm installed build status against McAfee SB10327.
  • Verify endpoint management reports show the updated ENS version after remediation.

Improper Link Resolution Before File Access ('Link Following')

Improper Link Resolution Before File Access ('Link Following') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
