Description

NVD

Improper certificate trust validation during VPN negotiation in Check Point Quantum Security Gateway may allow an unauthenticated remote attacker to execute arbitrary code on the Gateway.

CISA KEV entry

Check Point Multiple Products Improper Certificate Validation Vulnerability — Check Point / Multiple Products

Check Point Security Gateway and Check Point Spark Firewall using Site to Site VPN or Remote Access VPN contain an improper certificate validation vulnerability which could allow an unauthenticated remote attacker to execute arbitrary code on the Gateway.

Required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
