Security readout for executives and security teams
Plain-English summary
CVE-2017-3740 affects Lenovo Active Protection System before version 1.82.0.14. A locally privileged attacker could send commands to the embedded controller, potentially causing system denial of service or changing hardware functionality. This is mainly an endpoint hardening and availability risk, not a remotely exploitable internet-facing issue based on the provided sources.
Executive priority
Medium priority. The local-privilege requirement reduces immediate enterprise-wide urgency, but the hardware-control and denial-of-service impact makes it important for managed Lenovo fleets, especially shared systems or devices exposed to less trusted local users.
Technical view
The issue is in Lenovo Active Protection System earlier than 1.82.0.14. With local privileges, an attacker could issue embedded-controller commands. Documented impacts are denial of service and alteration of hardware functionality. The source bundle provides no CVSS vector, CWE mapping, model list, exploit details, or CPE coverage.
Likely exposure
Exposure is limited to Lenovo systems running Lenovo Active Protection System versions earlier than 1.82.0.14. The provided sources do not name specific Lenovo models, operating systems, or deployment prevalence, so asset inventory is required to determine scope.
Exploitation context
The provided data says exploitation requires local privileges. It does not show CISA KEV listing or cited evidence of active exploitation. Treat this as post-access risk: relevant if an attacker, malicious insider, or compromised local account can run actions on affected endpoints.
Researcher notes
Evidence is sparse: no CVSS, CWE, CPEs, exploit status, or affected model list is included. The key research question is whether a target has Lenovo Active Protection System before 1.82.0.14 and whether an attacker could gain local privileged execution there.
Mitigation direction
- Update Lenovo Active Protection System to version 1.82.0.14 or later.
- Review Lenovo advisory LEN-13637 for vendor-specific update guidance.
- Prioritize shared, kiosk, lab, and high-risk Lenovo endpoints.
- Restrict unnecessary local privileged access on affected systems.
- Monitor vendor guidance for model-specific instructions or superseding updates.
Validation and detection
- Inventory Lenovo endpoints for Lenovo Active Protection System installation.
- Check installed Active Protection System version against 1.82.0.14.
- Confirm remediation by verifying version after update.
- Review endpoint management records for unmanaged Lenovo devices.
- Document any systems that cannot be updated and why.
