CVE-2020-7331: Unquoted service executable path in McAfee Endpoint Security (ENS)

Unquoted service executable path in McAfee Endpoint Security (ENS) prior to 10.7.0 November 2020 Update allows local users to cause a denial of service and malicious file execution via carefully crafted and named executable files.

Security readout for executives and security teams

Plain-English summary

Older McAfee Endpoint Security installations may let a local user abuse an improperly quoted service path to run a malicious file or disrupt service. This is not described as remotely exploitable, but compromise of endpoint security software can carry high business impact.

Executive priority

Treat as a high-priority endpoint hygiene issue, not an internet-facing emergency. Remediate older ENS deployments promptly because exploitation of security tooling can undermine endpoint trust and response capability.

Technical view

CVE-2020-7331 is a CWE-428 unquoted service executable path flaw in McAfee Endpoint Security before 10.7.0 November 2020 Update. The CVSS 3.1 vector is local, low complexity, low privileges, no user interaction, with high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to systems running McAfee Endpoint Security versions prior to 10.7.0 November 2020 Update, especially shared workstations, servers, or endpoints where local users can place or execute files.

Exploitation context

The provided sources say exploitation requires local access and low privileges. They do not show CISA KEV listing or evidence of active exploitation. Impact includes denial of service and malicious file execution.

Researcher notes

Evidence is limited to CVE metadata and the McAfee advisory reference. No affected CPEs or public exploit status are provided in the bundle. Validate by version and vendor advisory applicability, not by attempting exploitation.

Mitigation direction

  • Upgrade McAfee Endpoint Security to 10.7.0 November 2020 Update or later.
  • Review McAfee advisory SB10335 for vendor-specific remediation guidance.
  • Prioritize endpoints where local users can run files or share workstations.
  • Restrict unnecessary local user access until affected ENS installations are remediated.

Validation and detection

  • Inventory installed McAfee Endpoint Security versions across managed endpoints.
  • Identify systems older than 10.7.0 November 2020 Update.
  • Check endpoint management records for completed ENS update deployment.
  • Confirm vendor advisory SB10335 applies before closing findings.
