Quantum Security Gateway
Monthly
Privilege escalation in Check Point Gaia Portal allows an authenticated user holding only read-only administrative privileges to execute arbitrary commands as root, giving full compromise of the affected Quantum Security Gateway or Security Management appliance. The flaw (CWE-269, improper privilege management) is vendor-reported via advisory sk185153 and carries a CVSS 3.1 base score of 7.5 with high attack complexity. No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Authentication bypass in Check Point Quantum Security Gateway and Spark Firewalls allows unauthenticated remote attackers to establish Remote Access and Mobile Access VPN sessions without valid credentials by abusing a logic flaw in deprecated IKEv1 certificate validation. The flaw (CVSS 9.3, CWE-287) was reported by Check Point themselves and publicly available exploit code exists, though EPSS exploitation probability remains very low (0.01%) and the issue is not currently listed in CISA KEV. Affected deployments include multiple Quantum R80.40-R82.10 trains and Spark R80.20.X-R82.00.X firmware.
Certificate validation bypass in Check Point Quantum Security Gateway and Spark Firewalls allows network-positioned attackers to subvert IKEv1 certificate-based authentication in site-to-site VPN tunnels. A man-in-the-middle adversary can intercept or modify traffic traversing the tunnel without possessing valid credentials. No public exploit identified at time of analysis, and the issue is constrained to the deprecated IKEv1 protocol path.
Unauthenticated information disclosure in Check Point Quantum Security Gateway allows remote attackers to read internal files on the appliance when the Identity Awareness blade is configured with Browser-Based Authentication. The flaw maps to CWE-98 (PHP file inclusion) and carries a CVSS 7.5 with confidentiality-only impact; EPSS is low (0.10%) and there is no public exploit identified at time of analysis, but the unauthenticated network reach against a perimeter gateway makes triage urgent for affected deployments.
Denial of service in Check Point Quantum Security Gateway allows remote unauthenticated attackers to crash the VPN processing service by sending specially crafted IKE packets over NAT-T (UDP/4500). Multiple supported releases (R81.10 and below, R81.20, R82, R82.10) are affected up to specific Jumbo Hotfix takes. No public exploit identified at time of analysis, and EPSS is low at 0.06% (17th percentile), suggesting limited near-term exploitation likelihood despite the 8.1 CVSS score.
Denial of service in Check Point Quantum Security Gateway allows remote unauthenticated attackers to terminate the VPN service by sending a malformed IKE fragment to UDP port 500 during the early phase of a connection attempt. The flaw affects multiple R81.x, R82, and R82.10 release trains running below specific Jumbo Hotfix Takes; no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.02%, 5th percentile).
Heap-based buffer overflow in Check Point Quantum Security Gateway's HTTP-based service allows unauthenticated remote attackers to cause availability disruption by sending crafted malformed HTTP requests requiring no authentication or user interaction. Affected deployments span all R81.10 releases and below, R81.20 through Jumbo Hotfix Take 127, R82 through Jumbo Hotfix Take 91, and R82.10 through Jumbo Hotfix Take 19. No public exploit identified at time of analysis, though SSVC classifies the attack as automatable with total technical impact - a meaningful tension with the CVSS A:L rating that security teams should scrutinize before deprioritizing.
SQL injection in Check Point Quantum Security Gateway's UserCheck Web Portal allows a remote unauthenticated attacker who can reach the UserCheck Ask page to manipulate the Security Gateway's stored DLP incident database when the DLP blade is active. Successful exploitation can cause loss of stored incident entries, disruption of pending approval workflows, or resource exhaustion through repeated abuse - all of which could undermine the integrity of an organization's data loss prevention audit trail. No public exploit code has been identified and EPSS is very low at 0.06% (18th percentile), with no CISA KEV listing at time of analysis.
