CVE-2026-16232: Checkpoint Quantum Security Management auth bypass ...

Check Point SmartConsole, the administrative client used to manage Quantum Security Management and Multi-Domain Security Management, contains an authentication bypass (CWE-287) in its login process that allows an unauthenticated remote attacker to obtain an application login token and authenticate with full administrative privileges. Exploitation is possible when the Management Server IP address is reachable from the internet and the configuration does not restrict Trusted Clients. A successful attacker can modify security policies and security configurations, effectively taking control of firewall management. Any organization running an internet-exposed Check Point management server without Trusted Client restrictions is affected, though Check Point reports exploitation has impacted only a very small number of customers. The flaw was added to CISA's KEV on 2026-07-22, is actively exploited, and press reports indicate public proof-of-concept code has been released.

Do: Apply the fix released in Check Point's advisory for CVE-2026-16232 by updating SmartConsole and the associated Quantum/MDS management software; no fixed version numbers were provided in this data, so confirm them against the vendor bulletin. As an interim mitigation, restrict internet access to the Management Server IP address and configure Trusted Clients so SmartConsole connections are accepted only from known administrator addresses. Review management logs for unexpected logins, unauthenticated token issuance, or unfamiliar administrator sessions, and complete remediation per CISA BOD 26-04 given the KEV listing.
