On June 16th, the Department of Homeland Security and CISA ICS-CERT issued a critical security advisory warning covering multiple newly discovered vulnerabilities affecting Internet-connected devices manufactured by multiple vendors. This set of 19 vulnerabilities in a low-level TCP/IP software library developed by Treck has been dubbed “Ripple20” by researchers from JSOF.
A networking stack is a software component that provides network connectivity over the standard internet protocols. In this specific case these protocols include ARP, IP (versions 4 and 6), ICMPv4, UDP and TCP communications protocols, as well as the DNS and DHCP application protocols. The Treck networking stack is used across a broad range of industries (medical, government, academia, utilities, etc.), from a broad range of device manufacturers – a fact which enhances their impact and scope, as each manufacturer needs to push an update for their devices independently of all others. In other words, the impact ripples out across the industry due to complexities in the supply and design chains.
