By default, many of Belkin wireless routers using a default ssid of "belkin54g" are preconfigured with a default password. The "admin" account has a null password which is publicly known and documented. This allows attackers to trivially access the program or system.

Thank you google for making 18293 the most popular vulnerability, week by week, on all of OSVDB. Clearly a lot of people are looking for their router password.
