The security issue is, as I see it, the short password. A 6 character PW
can be found by John the Ripper in just a few seconds. My own minimum user
password length is 9, and my root PW on this machine is, lets just say,
more than 20. Same for the admin password on dd-wrt. John would have to
work till the universe runs down to find those, as every character added
adds to the factorial on the difficulty. To illustrate, a 6 char PW is
6!=720. 9!=362880. and 20!=2.43290200818e+18, a rather large number.
You have to make it expensive enough to crack your password that they get
bored and go looking for easier targets.
