NCSC Warns of Critical Check Point VPN Flaws as Large-Scale Exploitation Is Expected

Dutch NCSC warns of two critical CVSS 9.8 Check Point VPN flaws enabling unauthenticated remote code execution, urging immediate patching before mass exploitation.

The Dutch NCSC warned that CVE-2026-85102 and CVE-2026-85103, both rated 9.8 CVSS, allow unauthenticated remote attackers to execute arbitrary code on Check Point Quantum Security Gateway, Spark Firewall, and Security Management Server deployments when VPN is enabled. CVE-2026-85102 stems from improper certificate trust validation during VPN negotiation, while CVE-2026-85103 is a heap-based buffer overflow in ASN.1 certificate decoding. Check Point shipped emergency updates on September 9, 2026, including R82.10 Take 44, R82 Take 126, and R81.20 Take 166 or later, plus LivePatch for eligible systems. No public exploit code exists yet, but the NCSC rates exploitation likelihood high and recommends restricting UDP ports 500 and 4500 to known peers as a stopgap.

Pyramid Solutions NetStaX EtherNet/IP Stack

CISA flags critical CVE-2026-78012 (CVSS 9.8) stack buffer overflow in Pyramid Solutions NetStaX EtherNet/IP stacks below v5.6.1, risking crashes or remote attack vectors.

CISA republished Pyramid Solutions' advisory for CVE-2026-78012, a CWE-121 stack-based buffer overflow in the NetStaX EtherNet/IP stack versions prior to 5.6.1, scored CVSS 9.8. Large Class 3 explicit-message requests can exceed the application-side receive buffer without generating a CIP error, potentially causing memory corruption, device crashes, or a silent remote attack vector. All eight adapter and scanner DLL/development kit variants, including CIP Security editions, are affected across critical manufacturing, energy, water, and chemical sectors. No public exploitation has been reported.

Critical NetScaler Vulnerability Exploited in Attacks

CISA added critical Citrix NetScaler flaw CVE-2026-19490 (CVSS 9.3) to its KEV catalog after confirming exploitation of gateway and AAA virtual servers in the wild.

CISA warned that threat actors are exploiting CVE-2026-19490, a critical-severity flaw (CVSS 9.3) affecting NetScaler ADC and NetScaler Gateway appliances configured as a gateway (SSL VPN, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server. Citrix patched the bug on August 19, and Rapid7 warned it is remotely exploitable without authentication. Sensor data from Previdian shows exploitation ongoing since at least September 3, one day after a public exploit appeared on GitHub, with matching requests observed from three IPs across three countries. CISA added the flaw to its Known Exploited Vulnerabilities catalog, giving federal agencies three days to patch under BOD 26-04.

CISA Warns of N-able N-central RCE Vulnerability Exploited in the Wild

CISA added CVE-2026-86218, a CVSS 10.0 unauthenticated RCE in N-able N-central RMM, to its KEV catalog; on-premises admins must patch to 2026.3.1.14.

CISA added CVE-2026-86218, a CVSS 10.0 static code injection (CWE-96) enabling unauthenticated RCE in N-able N-central, to the Known Exploited Vulnerabilities catalog on September 8, 2026. The flaw affects all on-premises builds before 2026.3.1.14 across the 2025.4 through 2026.3 release lines; N-able shipped Hotfix 4 for 2026.3 on September 5-6, 2026. Huntress research indicates at least one customer's N-central instance was compromised on September 4, and federal civilian agencies must mitigate by September 11 under BOD 26-04. Hosted environments were patched server-side, but a compromised RMM server can serve as a single point of entry into entire MSP client bases.

Ethiack fingerprinted 121 internet-exposed vulnerable deployments across 39 countries, 89% tied to government or military agencies. No exploitation in the wild or KEV listing was reported at disclosure.

Researchers open-source a Wi-Fi cyber range for security training

NTNU and Aegean researchers open-source a software-emulated Wi-Fi cyber range using mac80211_hwsim with LLM-assisted scenario building.

Researchers from the Norwegian University of Science and Technology and the University of the Aegean published a design and prototype for a cyber range dedicated to IEEE 802.11 security training, emulating access points and clients with mac80211_hwsim, Linux namespaces, hostapd, wpa_supplicant, dnsmasq, and FreeRADIUS. The platform bundles Aircrack-ng, Wireshark, and custom tools WPAxFuzz and Bl0ck, and can convert plain-language scenario descriptions into deployable definitions via a locally hosted Llama model. A working prototype covering scenario creation and deployment is on GitHub; monitoring, access control, and orchestration zones remain future work.

Critical N-able N-central Vulnerability and Active Exploitation

N-able N-central pre-auth RCE zero-day CVE-2026-86218 (CVSS 10.0) is exploited in the wild; on-prem admins must upgrade to 2026.3 HF4.

N-able disclosed a third N-central vulnerability, CVE-2026-86218, a pre-authentication RCE rated CVSS 10.0, and released hotfix 2026.3 HF4 superseding build 2026.3.1.13. Huntress reproduced an exploit chain involving an authentication bypass (CVE-2026-86206/CVE-2026-86207) after a fully patched customer's N-central production server was compromised on September 4. Attackers appended strings like .invalid to account names and probed the /remoteControlAction.do?method=getPierDetails endpoint; Huntress worked with Cloudflare to disable adversary tunnel infrastructure. Hosted N-central instances are already patched; on-prem administrators must upgrade immediately.

CVE-2026-86218 | N-able N-central Pre-Authentication Remote Code Execution Vulnerability

N-able N-central pre-auth RCE CVE-2026-86218 (CVSS 10.0) is actively exploited; CISA added it to KEV and a hotfix is available.

CVE-2026-86218 is a critical pre-authentication remote code execution flaw (CWE-96 static code injection) in N-able N-central servers, scored 10.0 CVSS 4.0 by N-able and 9.8 CVSS 3.1 by NIST. N-able fixed it in N-central 2026.3 Hotfix 4 (build 2026.3.1.14) on September 5, 2026, and has already patched hosted NCOD environments. CISA added the CVE to its Known Exploited Vulnerabilities catalog on September 8, 2026, citing evidence of active exploitation, though researchers have not attributed every reported N-central compromise to this flaw. Horizon3 released a NodeZero Rapid Response test to validate exposure and recommends log review for prior compromise.

Quantifying IIoT Sensor Node Criticality by Fusing its Data Criticality and Security Vulnerability

Researchers propose a Dempster–Shafer framework fusing IIoT sensor data criticality with CVSS 4.0/3.1 vulnerability scores to rank node criticality.

The paper introduces a framework that evaluates Industrial IoT sensor node criticality by fusing data criticality and cybersecurity vulnerability scores using Dempster–Shafer (D-S) theory. It was validated on a dataset from red wine production and is claimed to generalize to other industrial settings with minimal modification. Results show criticality rankings derived from CVSS 4.0 scores differ significantly from those derived from CVSS 3.1, underscoring how vulnerability scoring methodology affects security prioritization.

An Empirical Analysis of ReDoS Vulnerabilities and ReDoS Detection Tools

Study of NVD data finds ReDoS vulnerabilities growing more prevalent and more likely to be exploited, while five detection tools disagree substantially.

The study compares five publicly available ReDoS detection tools and one regex correction tool across three datasets. An empirical analysis of all ReDoS vulnerabilities reported to the NVD finds they are becoming more prevalent and are much more likely to be exploited than non-ReDoS weaknesses. The detection tools exhibited substantial disagreement on whether a given regex is vulnerable.
