If you care at all about security and privacy, a recent security analysis of the D-Link DWR-932 B LTE router will make your head explode.
Researcher Pierre Kim found an amazing set of security vulnerabilities that should embarrass a first year developer.
First, by default you and SSH and Telnet (yes Telnet!) into the router using the root or admin accounts. These accounts have preset passwords of “admin” and “1234” respectively. People, you should never set up fixed accounts like this, and if you do don’t use trivial passwords!
Of course it gets worse. There is also a backdoor on the routers. If you send “HELODBG” to port 39889 it will start a telnet demon which provides access to root without any authentication at all. My head is starting to look like the guys at the end of Raiders of the Lost Ark.
Just for fun they have a fixed PIN number for WiFi Protected Setup, many vulnerabilities in the HTTP daemon, major weakness in their over the air firmware updating, and anyone on the LAN can also create any port forwarding rule on the router for any port.
It is amazing that one product could have such a comprehensive set of catastrophic security failures. It certainly begs the question of how well they secure any of their other products.
