Why user has permissions to execute 'init 0'?
Hi all.
On one workstation run Solaris 10 a simple user can to execute 'init 0' command without input (su and root password).
Example:

Code:
% init 0
%
OK

I don't understand how user can execute 'init 0' command on this workstation?

1) I checked /usr/local/etc/sudoers all lines are commented.

2) I checked RBAC.

Code:
%roles
no roles

3) init permissions
Code:
  
/sbin:
-r-sr-sr-x         1   root    sys        init

Code:
/etc:
lrwxrwxrwx  1    root     root       init -> ../sbin/init


What I must check yet?

might be because of the "s" permissions. The command, though is initiated by a regular user, is executed as root.
Try changing it to the default r-xr-xr-x root sys

Is default permissions of /sbin/init -r-xr-xr-x???

That's right, the defaults for /sbin/init are: User = root, Group = sys, Mode = 0555 (r-xr-xr-x).

It seems, if I will change permissions /sbin/init to -r-sr-sr-x only, on any workstation.
Will any user can execute 'init 0' command?

I tried on my workstation, bootadm will not execute the command unless you are the root user

Yes, that's the very purpose of the setuid bit on executables.
