Full Discussion: Why /bin/su permission with SUID?
Operating Systems AIX Why /bin/su permission with SUID? Post 302910425 by achenle on Thursday 24th of July 2014 11:29:52 AM
Old 07-24-2014
There's no other way to say it, so I'll say it: your auditor is incompetent.

There are numerous setuid programs in any Unix or Unix-style OS. Many of them need to be setuid for them to operate properly. "su" is one. X windows servers tend to be another. "passwd" also needs to be setuid or users won't be able to set their own passwords. Don't tell me that audit report says to remove the setuid bit from "passwd"...

There are many others, too.

I'd be real careful following the recommendations of that audit report. You're likely to find yourself with non-working systems.

fs_getcellstatus

FS_GETCELLSTATUS(1)					       AFS Command Reference					       FS_GETCELLSTATUS(1)

NAME

       fs_getcellstatus - Reports whether setuid programs are honored in a cell

SYNOPSIS

       fs getcellstatus -cell <cell name>+ [-help]

       fs getce -c <cell name>+ [-h]

DESCRIPTION

       The fs getcellstatus command reports whether the Cache Manager allows programs fetched from each specified cell to run with setuid
       permission. To set a cell's setuid status, use the fs setcell command; fs_setcell(1) fully describes how AFS treats setuid programs.

OPTIONS

       -cell <cell name>+
	   Names each cell for which to report setuid status. Provide the fully qualified domain name, or a shortened form that disambiguates it
	   from the other cells listed in the local /etc/openafs/CellServDB file.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output reports one of the following two values as appropriate:

	  Cell <cell> status: setuid allowed
	  Cell <cell> status: no setuid allowed

EXAMPLES

       The following example indicates that programs from the cell "abc.com" are not allowed to run with setuid permission.

	  % fs getcellstatus abc.com
	  Cell abc.com status: no setuid allowed

PRIVILEGE REQUIRED

       None
