Setuid script on /tmp?
Given that /tmp isn't mounted with correct flags of course,

And given that you're really the legitimate root on the machine.
Otherwise it's social engineering and race conditions.

But for a legitimate root, just boot -s on a cd, mount the / of the boot disk in rw and change the pw.

And if you're not the legitimate root, do you really expect us to tell you how?

White hats won't beacause it's wrong, black hats wont's because it's not funny, and gray hats won't because it's not intresting.
