COMMAND
Netscape FastTrack
SYSTEMS AFFECTED
Win NT running FastTrack v3.01
PROBLEM
Matthew Patton found following. Whereas almost every other robust
webserver treats lowercase "get/pub/head" as illegal operations
and spits back a nice or not so nice error, FastTrack provides a
directory listing!!
Most disturbingly, directory access control methods (at least
when using .nsconfig files) are completely sidestepped -
directories to which users have no privs to see are happily listed
to them but apparently only 1 level deep since the presence of a
'/' seems to kick the server into doing the right thing. Even in
areas in which no control is being asserted AND despite the
presense of index.html (or equiv) you can get a directory listing
this way. Example:
get /foo
provides a file list whereas
get /foo/bar
doesn't. Attempts to fetch the files in the now exposed directory
fail like they should, so not all is lost.
SOLUTION
FastTrack/Enterprise v2 don't seem to be susceptible. Enterprise
v3 server that was tested also did not exhibit this flaw. To
solve the problem, turn off directory browsing completely (see
Netscape KB for details) and scream till a patch is produced.
