2019 Cybersecurity Insights -18

August 26, 2020

UPnP is short for Universal Plug and Play. UPnP is an architecture that defines peer-to-peer connectivity of PCs and intelligent devices (or instruments). Built upon Internet standards and technologies (such
as TCP/IP, HTTP, and XML), UPnP allows such devices to connect to and collaborate with each other automatically, thus making it possible for the network (especially home networks) to be accessible to more people. Therefore, many routers have this service that is publicly available. Within the UPnP protocol stack, Simple Service Discovery Protocol (SSDP) is used to discover devices in the local area network (LAN) and Simple Object Access Protocol (SOAP) is used for device control. For more basic knowledge of UPnP and vulnerability introduction, refer to NSFOCUS’s 2018 Annual IoT Security Report 1.

As for devices with the UPnP SSDP service publicly available, China, South Korea, Venezuela, the USA, and Japan had the most such devices exposed. Meanwhile, we found that devices exposed in Russia registered a decrease of 84% as compared to 2018. It is estimated that related Russian authorities had pushed forward UPnP governance.
