Information Disclosure in Internet-Facing Check Point Quantum Security Gateways
CISA: Check Point Quantum Security Gateways Information Disclosure Vulnerability
Check Point Quantum Security Gateways contain an information disclosure flaw (CWE-200) that can expose information stored on the appliance to unauthorized parties. It is triggered when an attacker targets a gateway connected to the internet with IPSec VPN, Remote Access VPN, or Mobile Access enabled, sending crafted requests to the exposed VPN services. A successful attacker gains unauthorized access to information on the gateway, and CISA notes known use of this flaw in ransomware campaigns. The issue spans multiple Check Point product lines: CloudGuard Network, Quantum Scalable Chassis, Quantum Security Gateways, and Quantum Spark Appliances. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV catalog on 2024-05-30 with ransomware use listed, and EPSS assigns a 100% probability of exploitation within 30 days, though no public proof-of-concept is known.
What to do: Apply the hotfix Check Point distributes per its advisory (SK170863) to all internet-facing gateways running IPSec VPN, Remote Access VPN, or Mobile Access; this is also the CISA KEV required action. Where the hotfix cannot be applied immediately, restrict or disable the Remote Access VPN and Mobile Access software blades as an interim mitigation. Review gateway and VPN logs for signs of exploitation and prioritize remediation given confirmed ransomware use.
