A remotely exploitable, high‑severity vulnerability in the Synectix LAN 232 TRIO serial‑to‑Ethernet adapter (CVE‑2026‑1633) leaves the device’s web management interface completely unprotected, allowing unauthenticated attackers to change critical configuration, erase device state, or...

A critical, high‑impact vulnerability in Johnson Controls’ Metasys product line — tracked as CVE‑2025‑26385 in vendor advisories — demands immediate attention from building‑automation teams, Windows administrators, and any organization that uses Metasys ADS/ADX servers, LCS/NAE appliances or the...

Johnson Controls’ iSTAR Configuration Utility (ICU) tool has a newly disclosed vulnerability — a stack‑based buffer overflow assigned CVE‑2025‑26386 — that can crash the Windows host running the utility and, in certain conditions, enable more severe host‑impact outcomes if exploited. The...

Two newly disclosed vulnerabilities in Rockwell Automation’s Verve Asset Manager expose plaintext secrets in retired, optional components — a wake-up call for OT teams that still run legacy modules and for Windows‑centric engineering workstations that serve as gateways into industrial networks...

CISA and the UK National Cyber Security Centre have jointly published practical guidance—Secure Connectivity Principles for Operational Technology (OT)—offering an eight‑point framework to design, secure, and manage connectivity into OT environments as organizations face rising business...

CISA’s latest notice that it has released two Industrial Control Systems advisories underscores a simple but urgent fact: vulnerabilities in operational technology (OT) and medical-device software continue to present high-impact risks to critical infrastructure and patient safety, and they...

CISA’s latest consolidated bulletin parcels out nine Industrial Control Systems (ICS) advisories that expose a familiar — and escalating — set of risks: remotely exploitable firmware and protocol flaws, weak authentication and hard-coded credentials, and insecure management interfaces that...

Rockwell Automation has published an urgent advisory after internal fuzz-testing uncovered two controller defects that can crash or fault Micro800-series devices: an IPv6 stack fault that produces recoverable controller faults (CVE-2025-13823) and a malformed-CIP handling flaw that can drive...
