CVE-2020-7291: Privilege Escalation vulnerability MAR for Mac

Privilege Escalation vulnerability in McAfee Active Response (MAR) for Mac prior to 2.4.3 Hotfix 1 allows a malicious script or program to perform functions that the local executing user has not been granted access to.

Security readout for executives and security teams

Plain-English summary

CVE-2020-7291 is a local privilege escalation flaw in McAfee Active Response for Mac. A user who can run a malicious script or program on an affected Mac could perform actions they were not authorized to perform. The business risk is highest where MAR is deployed on managed Macs and local compromise is plausible.

Executive priority

Treat as a high-priority endpoint hardening issue, not an internet-wide emergency. Patch affected Macs promptly because successful exploitation could undermine endpoint security boundaries after initial local compromise.

Technical view

The issue affects McAfee Active Response for Mac 2.4.x before 2.4.3 Hotfix 1. It is classified as CWE-274 and rated CVSS 7.8. The vector is local, high complexity, low privileges required, no user interaction, changed scope, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to macOS endpoints running McAfee Active Response 2.4.x before 2.4.3 Hotfix 1. The attacker must already have local execution as a low-privileged user, so this is most relevant after phishing, malware, or insider activity.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The flaw is not remotely exploitable by itself, but it could increase impact after an attacker gains local code execution on a Mac endpoint.

Researcher notes

Evidence is limited to the CVE record and McAfee advisory reference. The bundle identifies affected versions, impact, CVSS vector, and fixed threshold, but does not provide root-cause detail, exploit maturity, or operational indicators.

Mitigation direction

  • Upgrade affected MAR for Mac deployments to 2.4.3 Hotfix 1 or later per vendor guidance.
  • Prioritize Macs where MAR is installed and users can execute local scripts or untrusted programs.
  • Restrict local script execution and software installation where business operations allow.
  • Review McAfee advisory SB10317 for any deployment-specific instructions or caveats.

Validation and detection

  • Inventory macOS endpoints for McAfee Active Response 2.4.x installations.
  • Confirm each MAR for Mac installation is at 2.4.3 Hotfix 1 or later.
  • Check endpoint management records for systems missing the hotfix.
  • Review security telemetry for suspicious local scripts interacting with MAR functions.

Improper Handling of Insufficient Privileges

Improper Handling of Insufficient Privileges represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
