Enable another uid-0 account, such as the one called toor?  Setup sudo access 
for some other account which can run passwd or a shell as root, gaining 
superuser perms via the account password?

Note that having someone untrusted gain superuser access to a machine should be 
cause for backing up the system and reinstalling from scratch or restoring from 
a known-OK backup....
