Dutch NCSC Warns: Critical Check Point VPN Flaws Put Networks at Risk
Dutch NCSC warns two CVSS 9.8 Check Point VPN flaws enable unauthenticated RCE; patch and restrict access before exploitation begins.
The Dutch NCSC warns that CVE-2026-85102, a security-check bypass in the VPN negotiation process, and CVE-2026-85103, a heap overflow in the certificate ASN.1 decoder, both carry a CVSS score of 9.8 and allow unauthenticated remote code execution on Check Point Security Gateways and Security Management Servers. Check Point fixed the flaws on September 9 via advisories sk1000117 and sk1000118, covering R81.20, R82, R82.10, R81.10.x, R82.00.x plus end-of-support versions R80 through R81.10; R82.20 is unaffected. No public proof-of-concept exists, but the NCSC rates exploitation likelihood as high and recommends patching immediately via LivePatch Take 24 or Jumbo Hotfix and restricting VPN access to trusted IPs.
