The use of /usr/ucb suggested that you are using SunOS. I tried a similiar script and verified that SunOS 5.6 does indeed support setuid shell scripts. Whoa! I didn't know that...
I tried the following script also setuid to root and invoked by an ordinary user:
And I tracked down the ksh command in "ps". It showed up as "/usr/bin/ksh /dev/fd/3". Any unix version with a fd psuedo-filesystem can use the same trick. This closes that nasty setuid shell script problem completely. This doesn't mean that setuid shell scripts are totally safe, but they are as safe as they would be if sudo invoked them.

Hi,
When I listed one directory in Sun, it showed that :

shells
shells(4) File Formats shells(4)NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
/bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh,
/usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.
Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
