Johnson Controls Fire Safety System Exposes Credentials in Memory: CVE-2026-27875 Analysis
Johnson Controls Simplex Incident Manager versions 2.01 and earlier contain a critical vulnerability (CVE-2026-27875) that stores user credentials including passwords and authentication tokens in unencrypted form within system memory. This cleartext storage vulnerability allows local attackers with low privileges to extract sensitive authentication data using memory-dumping tools, potentially leading to unauthorized access to fire safety systems and connected critical infrastructure. The vulnerability affects fire safety management systems deployed worldwide across critical manufacturing, commercial facilities, government services, transportation systems, and energy sectors. Johnson Controls has released patched version 2.01.01 to address this security flaw and recommends immediate upgrades along with enhanced access controls and endpoint monitoring. This incident highlights the growing concern over insecure credential management in industrial control systems as threat actors increasingly target OT environments. With fire safety systems being critical infrastructure components, credential exposure vulnerabilities pose significant risks to facility security and emergency response capabilities.

Critical Unauthenticated Access Vulnerability in Synectix LAN 232 TRIO
In February 2026, a critical vulnerability (CVE-2026-1633) was identified in the Synectix LAN 232 TRIO 3-Port serial to Ethernet adapter. This flaw allows unauthenticated users to access the device's web management interface, enabling them to modify critical settings or perform a factory reset. The vulnerability has a CVSS score of 10.0, indicating maximum severity. Synectix is no longer in business, leaving the affected devices without official support or patches. ([securityonline.info](https://securityonline.info/unpatchable-critical-cisa-issues-cvss-10-0-alert-for-synectix-adapters/?utm_source=openai)) This incident underscores the risks associated with using unsupported legacy devices in critical infrastructure. Organizations must proactively identify and replace such equipment to mitigate potential security threats.

Critical Vulnerabilities in Johnson Controls iSTAR Devices Expose Critical Infrastructure—What You Need to Know
In December 2025, Johnson Controls disclosed two critical vulnerabilities (CVE-2025-43875, CVE-2025-43876) affecting its iSTAR Ultra and Edge G2 access control devices worldwide. These vulnerabilities—improper neutralization of special elements used in OS commands (CWE-78)—can be exploited remotely with low complexity and limited privileges, potentially granting attackers unauthorized access to devices deployed across critical sectors, including commercial facilities, manufacturing, energy, transportation, and government. There are currently no reports of active exploitation, but if leveraged, these flaws could compromise physical security and facility operations. This incident underscores the persistent cybersecurity challenges in operational technology and building automation environments. The disclosure highlights an urgent need for regular patching, segregation of critical controls, and adoption of defensive measures, especially as threat actors increasingly target industrial and physical security systems with potentially far-reaching consequences.

Johnson Controls iSTAR Ultra Vulnerabilities: 2025 Exposure of OT Systems
In December 2025, Johnson Controls publicly disclosed critical vulnerabilities (CVE-2025-43873 and CVE-2025-43874) affecting several versions of its iSTAR Ultra and Edge G2 door controllers used in building automation across critical infrastructure sectors worldwide. These OS Command Injection flaws, exploitable remotely with low attack complexity and minimal user interaction, could allow attackers to gain full control of vulnerable devices, modify firmware, and potentially disrupt or compromise secure building environments. The vulnerabilities were responsibly reported by Reid Wightman of Dragos, and patches have been made available for affected products. This incident highlights increasing threats targeting operational technology (OT) in critical sectors, as cybercriminals and nation-state actors leverage software supply chain and device-level weaknesses for initial access. The prevalence of command injection vulnerabilities, coupled with rising demands for segmentation and zero trust architectures, elevates the urgency for organizations to update OT and IoT assets and enforce proactive defense strategies.
