12 wide-impact firmware vulnerabilities and threats

Venture Memoria and flaws in embedded TCP/IP stacks

Many client IoT units these days, reminiscent of routers, modems, network-attached storage (NAS) bins, and community video recorders (NVRs) use firmware primarily based on the Linux kernel. However industrial and medical embedded units nonetheless depend on proprietary real-time working methods (RTOSes) reminiscent of VxWorks for his or her firmware.

Regardless that this implies there may be extra firmware variety within the industrial IoT world, there are nonetheless some elements that may be shared by completely different RTOSes, together with TCP/IP stacks. These complicated codebases implement a few of the Web’s core protocols — DNS, HTTP, FTP, ARP, ICMP, and many others. — and had been written a long time in the past as proprietary libraries that had been then offered to embedded working system distributors.

In 2020, researchers from safety agency Forescout in collaboration with universities and different corporations launched a venture to research proprietary TCP/IP stacks utilized in industrial units. Generally known as Venture Memoria, the analysis lasted 18 months and led to the invention of 104 vulnerabilities, many crucial, in a number of TCP/IP stacks and libraries utilized in over 250,000 embedded gadget fashions from greater than 500 distributors.
