Multiple vulnerabilities have been announced in libupnp, the open source portable SDK for UPnP devices. Libupnp is employed by hundreds of vendors for UPnP-enabled devices. Information is also available in CERT Vulnerability Note VU#922681.
US-CERT recommends that affected UPnP device vendors and developers obtain and employ libupnp version 1.6.18, which addresses these vulnerabilities.
US-CERT recommends that users and administrators review CERT Vulnerability Note VU#922681, disable UPnP (if possible), and restrict access to SSDP (1900/udp) and Simple Object Access Protocol (SOAP) services from untrusted networks such as the Internet.Refer this to hardware vulnerabiity such as Wifi Routers, etc.
