If there’s malware already on the local LAN, there’s not much need to open ports anymore - it can already set up outgoing connections that are much harder to detect, or attack internal servers locally. The question if this is a real threat for home uses hinges on whether this UPnP flaw can be exploited from the outside. Although it isn’t ideal that many router interfaces don’t seem to make a distinction, and you often can’t for example disable UPnP but keep NAT-PMP/PCP enabled. The concept of Upnp is an extension of plug-and-play, a technology for dynamically attaching devices directly to a computer. MCPlayer is a high definition (HD) wireless video player for iOS devices: watch your favorite videos streamed directly. This useful Xtreamer application allows you to have an easier access to the UPnP Server and its full power. Watching your favorite movies, music videos, and video files has never been easier and more fun, thanks to the Media Center Video Player. It also encourages using a fixed port, where automatic can more easily randomize ports.īut it is probably a good idea to move from UPnP-IGD to more modern protocols like NAT-PMP and PCP. MCPlayer, is a wireless streaming video player application for iPad and iPhone. Manual port forwarding and automatic port forwarding both have security drawbacks - automatic means it’s only as safe as its implementation, manual means having to open up the router interface to users to make configuration changes, and also risks forgetting to (manually) close ports again once they’re not needed anymore. This is a somewhat confusing article - in the first paragraph it asserts that the flaw is in the UPnP protocol, but from the article I understand it’s not the protocol itself but certain implementations?
