Buffalo LinkStation LS-WTGL Default Admin Account & Guest Access Information

[Darius Freamon <darius.freamon () gmail com>]

After reading l0rd lunatic's post about the Buffalo router
(http://seclists.org/fulldisclosure/2012/Nov/234), noticed that going
to login page and clicking 'help' will show you the default admin
account. I think that is what he meant about information disclosure!
It also lets you login as guest and provides more information.

Clicking help:
