It’s also recommended to enable user authentication in the Red Lion RTU and block access over TCP to the affected RTUs.\\n\\n\\n\\nAccording to an alert issued by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) in November 2023, the flaws impact the following products -\\n\\n * ST-IPm-8460: Firmware 6.0.202 and later\\n * ST-IPm-6350: Firmware version 4.9.114 and later\\n * VT-mIPm-135-D: Firmware version 4.9.114 and later\\n * VT-mIPm-245-D: Firmware version 4.9.114 and later\\n * VT-IPm2m-213-D: Firmware version 4.9.114 and later\\n * VT-IPm2m-113-D: Firmware version 4.9.114 and later\\n\\n\\n\\n\\”Red Lion’s RTUs are prominent in many industrial automation settings, and an attacker with access to the devices and the ability to run commands at root presents significant possibilities for process disruption or damage,\\” Claroty noted.\\n\\nFound this article interesting?
