About this tag
OT security on WindowsForum covers operational technology vulnerabilities and advisories relevant to administrators managing hybrid IT/OT networks. Recent discussions include CISA alerts on industrial control system flaws such as CVE-2026-1840 in Hubbell Aclara web interfaces, B&R Linux kernel privilege escalation bugs, Hitachi RTU500 firmware issues, and warnings about internet-exposed automatic tank gauges. Other topics include cross-site scripting in Kieback & Peter building controllers, session hijacking in Siemens SIPROTEC 5 devices, and file-read vulnerabilities in Siemens Ruggedcom ROX. These threads emphasize that patch discipline, network segmentation, and treating industrial appliances as dynamic security risks are critical for protecting infrastructure that increasingly intersects with Windows and enterprise environments.
