These cybersecurity vulnerabilities could leave millions of connected medical devices open to attack

Critical vulnerabilities in millions of connected devices used in hospital networks could allow attackers to disrupt medical equipment and patient monitors, as well as Internet of Things devices that control systems and equipment throughout facilities, such as lighting and ventilation systems.

The vulnerable TCP/IP stacks – communications protocols commonly used in connected devices – are also deployed in other industries, including the industrial sector and the automotive industry.

The 13 newly disclosed vulnerabilities in Nucleus Net TCP/IP stacks have been detailed by cybersecurity researchers at Forescout and Medigate. Dubbed Nucleus:13, the findings represent the final part of Project Memoria, an initiative examining vulnerabilities in TCP/IP stacks used in connected devices and how to mitigate them.

The vulnerabilities could be present in millions of devices based around Nucleus TCP/IP stacks and could allow attackers to engage in remote code execution, denial of service attacks and even leak data – although researchers can’t say for certain if they’ve actively been exploited by cyber criminals.

Now owned by Siemens, the Nucleus TCP/IP stack was originally released in 1993 and is still widely used in critical safety devices, particularly in hospitals and the
