By default, many Belkin 54G 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 as the routers come preconfigured with remote telnet access enabled.

Currently, there are no known upgrades or patches to correct this vulnerability. It is possible to temporarily work around the flaw by implementing the following workaround: Ensure that the username and password for the router are immediately changed, and disable remote telnet access.
