In the fifth study of Project Memoria – NUCLEUS:13 – Forescout Research Labs and Medigate identified a set of 13 new vulnerabilities affecting the Nucleus TCP/IP stack. Nucleus is currently owned by Siemens. Its original release was in 1993 and, since then, it has been deployed in many industry verticals with safety and security requirements such as medical devices, automotive, and industrial systems. Upon identification of the new vulnerabilities, Forescout Research Labs and Medigate collaborated with Siemens, CISA, CERT/CC and other agencies to confirm the findings and notify vendors.
