writes "H.D. Moore of Rapid7 has discovered a set of security flaws in three different implementations of the set of common (and notoriously troublesome) networking protocols known as Universal Plug and Play, or UPnP. For nearly the last six months, he's been scanning the Internet for devices made vulnerable by those UPnP bugs, and has discovered somewhere between 40 and 50 million routers, printers, servers and other devices susceptible to some sort of hacker compromise via the public Internet. At least some routers from every major vendor are vulnerable. And 23 million of the devices could be completely taken over and used as Linux machines capable of attacking the rest of a victim's internal network.
Moore recommends that users disable UPnP on their networking gear and other devices immediately, and that ISPs even go so far as to push new firmware to consumers' home routers."Link to Original Source
