Default SUDO Wildcards


I have a php script that creates directories as ftp:ftp

Best thing I can think of is doing a simple php mkdir and then a sudo with chown and a specific parameters definition.

In my sudoers I have added:
www ALL= NOPASSWD: /usr/sbin/chown ftp\:ftp /exports/nasbezoom/volume[a-z0-9_ -/]*
This seems to work for:
sudo /usr/sbin/chown ftp:ftp /exports/nasbezoom/volume6
but also for:
sudo /usr/sbin/chown ftp:ftp /exports/nasbezoom/volume6/../blablabla
Am I doing something wrong with my wildcards?

Wrong? You just underestimate the significance of the "*" wildcard

From the sudoers manpage

       sudo allows shell-style wildcards (aka meta or glob characters) to be
       used in pathnames as well as command line arguments in the sudoers
       file.  Wildcard matching is done via the POSIX fnmatch(3) routine.
       Note that these are not regular expressions.

       *       Matches any set of zero or more characters.
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
