Researchers have uncovered three sets of serious security flaws in the protocol for a component that allows computers and other devices to easily connect and communicate on a network.
The flaws were found in Universal Plug and Play (UPnP), a component that is embedded in nearly 7,000 different kinds of devices — including routers, printers, media players and smart TVs — to allow them to be easily discovered on a network for quick setup and information sharing.
The flaws would allow hackers to steal passwords and documents or take remote control of webcams, printers, security systems, and other devices that are connected to the internet.
