AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated and network-reachable, but exploiting a certificate-trust flaw during VPN negotiation realistically requires interposing/crafting a malicious cert, so AC:H; successful RCE on the gateway gives full C/I/A.

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.
AnalysisAI
Remote code execution in Check Point Quantum Security Gateway arises from improper certificate trust validation during VPN negotiation, letting a remote unauthenticated attacker run arbitrary code on the gateway itself. The CWE-295 root cause means the gateway accepts or mishandles an untrusted/forged certificate in the IKE/SSL-VPN handshake, and processing that malicious certificate leads to code execution rather than merely a trust bypass. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to participate in a VPN negotiation with the Check Point Quantum Security Gateway and present a certificate during that handshake; the flaw lies in how the gateway validates certificate trust, so exploitation is bound to the VPN-negotiation code path (IKE/SSL-VPN) rather than arbitrary services. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:H = 9.8) paints a worst-case picture of trivial, unauthenticated, network-reachable full compromise of a security perimeter device - a scenario that warrants emergency patching because a compromised VPN gateway yields a foothold into the protected network. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fix described in the Check Point advisory at https://support.checkpoint.com/results/sk/sk1000117 (patch available per vendor advisory; an exact fixed version was not provided in the input and must be read from that SK). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Check Point Quantum Security Gateway appliances in production across your environment and immediately implement network-level access controls to restrict VPN gateway exposure only to trusted endpoints; enable enhanced logging and alerting for certificate validation errors and TLS handshake anomalies. …
