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.

SonicWall's SMA1000 boxes under active attack again

SonicWall warns attackers are chaining two SMA1000 zero-days, a CVSS 10.0 SSRF and command injection, to compromise VPN gateways.

SonicWall says attackers are actively exploiting two chained zero-days in SMA 1000 appliances: CVE-2026-83548, a pre-authentication SSRF rated CVSS 10.0, and CVE-2026-83549, a post-authentication OS command injection (CVSS 7.8) in the Appliance Management Console. Hotfixes are available for SMA 6210, 7210, and 8200v appliances with no workarounds; SonicWall recommends reimaging compromised devices, rotating passwords, and resetting TOTP tokens. NHS England assesses further exploitation as almost certain, following a similar exploited pair in July when CISA added CVE-2026-15409 to its KEV catalog.

2026-011: Critical Vulnerabilities in SAP Kernel and NetWeaver Message Server

SAP patched two critical flaws, OVERPASS (CVE-2026-44756, CVSS 10.0) and S4GET (CVE-2026-58240), allowing unauthenticated attackers to execute OS commands on SAP hosts.

On SAP's September 2026 Security Patch Day, SAP released Security Notes 3747649 and 3759472 fixing two critical unauthenticated remote vulnerabilities found by Onapsis. CVE-2026-44756 ('OVERPASS', CVSS 10.0) is a memory corruption flaw in Extended Passport (EPP) deserialisation in the SAP Kernel; CVE-2026-58240 ('S4GET', CVSS 9.8) is a missing authentication check in the NetWeaver Message Server that lets attackers register as trusted cluster nodes. Successful exploitation of either can yield OS command execution as the SAP service account, leading to full system and business data compromise, and CERT-EU urges immediate patching. No in-the-wild exploitation is reported.

FortiPAM Chrome Extension Vulnerability Lets Malicious Sites Control Browser Proxy and Record Tabs

Fortinet patched CVE-2026-84388 (CVSS 9.1) in its FortiPAM Chrome extension, letting malicious websites alter proxy settings, open tabs and record sessions.

The Fortinet FortiPAM Chrome extension flaw (CVE-2026-84388, CVSS 9.1) lets attacker-controlled domains be trusted as FortiPAM servers because a webRequest listener adds requested hostnames without verifying the initiator. A second issue exposes the extension's message interface to all URLs and accepts non-JWT tokens without validation, enabling unauthenticated session launches, proxy manipulation, tab control and recording; the consent dialog can also be bypassed via shadow-root clicks. Fortinet issued advisory FG-IR-26-168 after a July 17 report and released a fix on August 1, 2026, with no confirmed exploitation in the wild.

Attackers Exploit Two SonicWall SMA 1000 Zero-Days That May Form an Attack Chain

SonicWall patches two actively exploited zero-days (CVE-2026-83548, CVE-2026-83549) in SMA 1000 VPN appliances, likely chained for code execution.

SonicWall fixed CVE-2026-83548 (CVSS 10.0), a pre-authentication SSRF in the Appliance Work Place interface, and CVE-2026-83549 (CVSS 7.8), a post-authentication OS command injection in the Appliance Management Console. The company investigated a case indicating active exploitation, suggesting attackers chained both bugs to execute arbitrary code on susceptible devices. Affected SMA 1000 models 6210, 7210, and 8200v require hotfixes 12.4.3-03526 or 12.5.0-02952; customers are urged to hunt for IoCs and re-image, reset credentials, and rotate TOTP if found.

Cisco Fixed Critical RCE in Nexus 9000 Series Switches

Cisco patched CVE-2026-20212 (CVSS 9.8) in Silicon One-based Nexus 9000 switches, allowing unauthenticated remote root code execution via TCP ports 43210/43211.

Cisco patched CVE-2026-20212 (CVSS 9.8), a flaw in the Silicon One integration for Nexus 9000 Series switches that lets unauthenticated remote attackers execute code with root privileges. TCP ports 43210 and 43211 are exposed through the default Layer 3 VRF, and exploitation can also crash the S1HAL process, forcing device reloads. Cisco TAC discovered the flaw during a support case; PSIRT is not aware of public disclosure or malicious exploitation. Workarounds include infrastructure ACLs or blocking the exposed ports, alongside a Live Protect shield pending fixed NX-OS upgrades.

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.
