This really is not a www security issue.  It is could be a system
security problem depending on your connection to the 
Internet and if the router blocks NFS  

It is not advised that you export Filesystems with no restrictions.
If you must export globally then you at least want to export the
filesystems read only.

Check your /etc/exports for a list of what you are exporting

   If it doesn't do what you want, subclass and override.
