When I enable UpnP in Netgear 3700v2 I get lan access from remote from all over the world in router logs to my macbook pro snow leopard 10.6.8 and the my book live duo, using a DHCP connection. The router flashes like crazy. When I disable it I stops flashing crazy and the duo sleeps. I check the logs and it’s back to normal. No lan access and no Dos attacks, fin scans and the like. Netgear told me to keep off UpnP as it is not safe. And to change my router to my macbook pro’ address, which is also crazy. So now I get a relay connection and of course can not use it. Port Forwarding is dangerous too. I do not want unknown people accessing my computer. So how do I use this in a secure fashion? Any advise will be appreciated.
Have you looked at its FTP capability? you can port forward and still protect access with password protection.
Hi thanks for the response. I see ftp in the dashboard and in the router. Could you give me directions on what I need to do? I’m a dummie and I’d appreciate it very much.
According to this website wd is still using v1. Are they going to fix this?
UPnP Forum Responds to Recently Identified LibUPnP/MiniUPnP Security Flaw
Beaverton, Ore., USA – 8 February 2013: UPnP Forum – the global standards body that has paved the way for seamless connectivity between more than a billion devices – today responds to concerns over a security flaw identified by Rapid7 in the open source, third party libraries ‘libupnp’ hosted at SourceForge and MiniUPnP hosted at miniupnp.free.fr.
On January 29th, UPnP Forum members received the public news that Rapid7 has identified a security flaw in the open source, 3rd party stacks libupnp and MiniUPnP. Based on Rapid7’s white paper, the flaw is only in the implementation of old versions of libupnp (older than 1.6.18) and MiniUPNP (older than 1.4). The flaws are NOT associated with the UPnP specifications themselves or UPnP Forum’s certification process for UPnP stacks. In addition, the flaws outlined by Rapid 7 show an implementation responding to UPnP protocols on the WAN ports of routers that existing UPnP standards are not designed for. Existing UPnP protocols are only intended for LAN usage that is not forwarded on to the internet.
The UPnP Forum is encouraging all vendors using open source implementations of protocol stacks to ensure they are using the latest releases and are active in ensuring that the security of those stacks is maintained. In the case of the libupnp and MiniUPnP, the UPnP Forum has posted a message to its website to help consumers and vendors identify the problem in this third party software. Please note that other issues have been identified in the latest version of MiniUPnP, 1.4, but they won’t be publicly disclosed until the library’s developer releases a patch to address them, so we advise caution on any further usage of this stack until such time. We are also looking into test tool enhancements that can identify implementations coming for certification that continue to use this flawed older versions of UPnP stacks. Numerous other closed and open source stacks exist in the UPnP ecosystem to use as alternatives if you have remaining concerns over libupnp or MiniUPNP.
For gateway vendors both affected and unaffected by this identified flaw, the UPnP Forum continues to advise that vendors implement the latest version of the Internet Gateway Device (v2) rather than the V1 that is deployed today. Along with our Device Protection standard, this specification provides numerous enhancements for security as well as necessary enhancements like the growing deployment of IPv6.
