Red Hat Bugzilla – Bug 5265
becoming root without knowing root password
Last modified: 2008-05-01 11:37:51 EDT
RedHat Linux 6.0 allows to boot in single user mode (and
become root) without asking for the root password.
and you can do the same thing with linux init=/bin/bash.
Therefore, we won't change the 'linux single' behavior.

Are you aware that when the computer is sitting at the lilo:
prompt and you type 'linux 1', when it boots to single user,
you can use the passwd utility to change the root password
without knowing the root password!
I don't know if this is a bug or if this is supposed to be
this way. It just seems like it is not real secure.
I don't understand why this is marked as resolved. This is a major security
problem. On the Server this may not be an issue, but in a desktop environment
if a user knows how to type : linux init=/bin/bash
or some other command like that, this will allow them root or God access.
Is there some way to prompt a user for root password every time they type
something in, but if they use the menu option "tab" then no password is required
