    Subject: Nifty Security hole on Several NT Based Web Servers
    
    A collegue of mine discovered a very interesting bug in several Web
    server packages.  if you protect a file that is not 8.3 in its makeup
    you can often access the canonical name without restriction. EG:
    
    if a file named  "somelongfile.htm"  and you protect it then you can
    access somef~1.htm  if somel~1.htm is the canonical name. (don't recall
    the corect NT term). This also applies to directory names as well.
    
    We have notified some of the affected vendors but haven't tested all
    the various NT Web servers.
    
    Know to be affected are IIS 4.0, Netscape Enterprise 3.0x and Website
    Pro don't recall the version.

    When things can't get any worse, they simplify themselves by getting a whole
    lot worse then complicated. A complete and utter disaster is the simplest
    thing in the world; it's preventing one that's complex.       (Janet Morris)
