CVE-2020-7253: Improper access control vulnerability in McAfee Agent

Improper access control vulnerability in masvc.exe in McAfee Agent (MA) prior to 5.6.4 allows local users with administrator privileges to disable self-protection via a McAfee supplied command-line utility.

Security readout for executives and security teams

Plain-English summary

This weakness lets someone who already has local administrator rights on a machine running vulnerable McAfee Agent disable the agent’s self-protection using a McAfee command-line utility. It is not a remote entry point, but it can weaken endpoint defenses after admin control exists.

Executive priority

Treat as a moderate-priority endpoint hardening issue. It does not create initial access, but it can reduce security control resilience on already-compromised or poorly administered machines.

Technical view

CVE-2020-7253 is an improper access control issue in masvc.exe in McAfee Agent versions before 5.6.4. The CVSS vector is local, high complexity, high privileges required, no user interaction, with high integrity and availability impact and no confidentiality impact.

Likely exposure

Exposure is limited to endpoints running McAfee Agent 5.6.x before 5.6.4 where a local administrator account can execute McAfee-supplied tooling. The source bundle does not identify other affected products or versions.

Exploitation context

The CVE record does not indicate CISA KEV listing or active exploitation. Practical abuse requires local administrator privileges first, so this is mainly a defense-evasion and control-disabling risk after endpoint compromise or by a malicious administrator.

Researcher notes

The public data identifies the vulnerable component, privilege requirement, impact profile, and version boundary. It does not provide exploit prevalence, detailed attack paths, or separate mitigations beyond the vendor advisory context.

Mitigation direction

  • Check McAfee advisory SB10312 for vendor-approved remediation guidance.
  • Upgrade McAfee Agent installations before 5.6.4 to 5.6.4 or later.
  • Prioritize systems where local admin rights are broadly assigned.
  • Restrict and monitor local administrator access on managed endpoints.
  • Confirm endpoint self-protection remains enabled after updates.

Validation and detection

  • Inventory McAfee Agent versions across endpoints.
  • Flag any McAfee Agent 5.6.x installation below 5.6.4.
  • Review endpoint management logs for self-protection disable events.
  • Confirm only approved administrators can manage McAfee Agent settings.
  • Document exceptions and compensating controls for systems not updated.
