Sometimes you run into something security-related in the computer industry that’s so stupid it’s hard to believe. Here we go again:
Many routers and other network devices use default or hard-coded SSL keys that can be recovered from the device’s firmware. An attacker could then use the keys to listen in on HTTPS traffic to the administration interface of the device. The database has over 2,000 device keys from vendors including Cisco, Linksys, D-Link and Netgear.
So a group has started a project called littleblackbox that contains a database of devices and their private keys.
Strictly speaking, this isn’t a vulnerability; it’s poor implementation. I’d also venture to say that the impact is not all that great, as typically it only allows sniffing of traffic inside the network. If the attacker is already in control of a PC inside the network you’ve already got a big problem and he will have a high rate of success in controlling the network device simply by using default usernames and passwords. There are many databases of these, such as this one.
