Multiple critical vulnerabilities in Ruckus Wi-Fi routers used throughout the world were disclosed at the 36th Chaos Communication Congress in Leipzig, Germany, held from December 27-30, 2019. Although the devices examined were from the Ruckus Unleashed stable, Zror told SecurityWeek, "I believe the same issues will affect the Ruckus regular routers and other Ruckus devices. Without pre-authentication," he continued, "I can run my own code on those devices. The implication is that I can upload my own malware into the router, and manipulate all the router activity, as I wish. From there I can access any other network, including the corporate network, that may be connected or may also use Ruckus devices."
