Well, this is more or less true...mountd can be circumvented (hope i got this
 right) and one can send direct rpc/nfs requests to the nfsd...the hard part
 is actually guessing a valid file handle (32 byte number!).
 I have read in some documents that regular use of fsirand, a program which
 supposedly assigns to each file/dir a unique file handle, greatly reduces
 chances of a wild guess...

There are techniques you can exploit here that make hijacking an NFS
partition or simply destroying it way too simple.

  Name a few Perry, that's what bugtraq is for... Generally alluding to
  techniques is worthless.
