Today, «SD-WAN» is a very hot and attractive topic. Software-defined WAN (SD-WAN) is a technology based on software-defined network (SDN) approach applied to wide area networks (WAN) in enterprise networks. According to Gartner’s predictions study, more than 50% of routers will be replaced with SD-WAN solutions by 2020.
In this presentation, we disclose a set of vulnerabilities in widespread and most popular SD-WAN products including Citrix NetScaler and Silver Peak EdgeConnect. We present the new results of our research, consider some technical details of the insecure design and found vulnerabilities, and describe different attack scenarios that may allow an attacker to compromise SD-WAN control and data planes.
