Unix offers no security against local users either.  If I can sit at the 
console, I can login in single user mode, mount the drives rw and edit 
/etc/passwd all day.

Furthermore, I can take any hard drive, with any file system on it, and 
with the right tools I can read everything on the drive, even deleted stuff.

So what's your point?  That when you own the box you own the box?

If you first have to own the box to get to the information, then it's not a 
vulnerability.  It's not best practice, but it's not a vulnerability.
