In a previous post, we described the obsolete HNAP protocol, which has security vulnerabilities.
A new vulnerability was recently discovered in D-Link routers that support the HNAP protocol. You can read more about it here: http://www.computerworld.com/article/3138023/internet/another-hnap-flaw-in-d-link-routers.html.
You can use RouterCheck to determine whether your router supports this protocol.
