What is UPnP?
What is Universal Plug and Play (UPnP), and what are the associated vulnerabilities and exploitation?
Universal Plug and Play (or some may call it Universal Pwn and Play) is a service that allows devices on the same network to discover and interact with each other using standard networking protocols such as TCP and UDP, without any prior configurations.
UPnP can also be utilized to view and modify router configurations, such as the following:
