Attackers leveraged VPNs and proxies to obscure their origins, complicating detection and response efforts. This incident underscores the severe risk posed by unpatched internet-facing security appliances, which are high-value targets precisely because they sit at the perimeter of organizational networks. CISA's addition of both CVEs to the Known Exploited Vulnerabilities catalog reinforces that federal and private-sector organizations must treat perimeter device patching as a critical, time-sensitive obligation. Delays in patching security infrastructure can paradoxically make that infrastructure the entry point for the very threats it is meant to block.","**Immediate actions:**\n- Apply vendor-released patches for CVE-2026-85102 and CVE-2026-93616 to all affected Check Point Security Gateway instances immediately.\n- Restrict management web service access to trusted IP ranges only, minimizing the exposed attack surface while patches are deployed.\n- Review VPN and gateway logs for indicators of compromise dating back to at least July 23, 2026.\n\n**Long-term improvements:**\n- Establish an emergency patching SLA (e.g., 24–72 hours) specifically for internet-facing security appliances and perimeter devices.\n- Maintain a continuously updated, accurate inventory of all network appliances and their firmware\u002Fsoftware versions to enable rapid vulnerability scoping.\n- Implement network segmentation so that a compromised VPN gateway cannot provide direct lateral movement into core internal networks.\n\n**Detection measures:**\n- Subscribe to vendor security advisories and CISA's KEV catalog alerts to receive timely notification of actively exploited vulnerabilities.\n- Deploy anomaly-based monitoring on VPN authentication logs to detect unusual source IP patterns, including known VPN and proxy egress nodes.\n- Enable centralized SIEM ingestion of all perimeter device logs to support rapid threat hunting when new exploitation activity is disclosed.",[12,13,14,15,16,17,18,19,20,21],"CIS Control 7: Continuous Vulnerability Management","CIS Control 12: Network Infrastructure Management","CIS Control 13: Network Monitoring and Defense","NIST SP 800-40 Rev. 4: Guide to Enterprise Patch Management Planning","NIST SI-2: Flaw Remediation","NIST RA-5: Vulnerability Monitoring and Scanning","NIST SC-7: Boundary Protection","CISA KEV Catalog Binding Operational Directive 22-01","ISO\u002FIEC 27001:2022 Annex A 8.8: Management of Technical Vulnerabilities","ITIL 4: Change Enablement (emergency change procedures)","published","2026-09-23T20:20:23.578119+00:00","2026-09-23T20:20:23.459+00:00",{"id":7,"url":26,"slug":27,"title":28},"https:\u002F\u002Fwww.bleepingcomputer.com\u002Fnews\u002Fsecurity\u002Fcheck-point-warns-of-hackers-exploiting-security-gateway-vpn-rce-flaw\u002F","check-point-warns-of-hackers-exploiting-security-gateway-vpn-rce-flaw-702aeb","Check Point warns of hackers exploiting Security Gateway VPN RCE flaw",[30,36],{"id":31,"name":32,"slug":33,"description":34,"color":35},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":37,"name":38,"slug":39,"description":40,"color":41},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",[43],{"id":44,"date":45,"edition":46,"title":47,"audio_url":48},"5d335275-3c00-4c11-a4e9-bf17dccb2144","2026-09-24","morning","ThreatNoir Morning Brief — September 24","https:\u002F\u002Fcdn.threatnoir.com\u002Fpodcasts\u002F2026-09-24\u002Fthreatnoir-morning-brief-2026-09-24.mp3"]
