Netscape's Fasttrack server is supposed to display a directory listing if the follwing three conditions are met:
1: Directory listing is enabled
2: No filename is specified in the requested URL
3: There is no index file in that directory (defaults are index.html and home.html)
However, even with an index file in the directory, if you telnet to the httpd port and type 'get/' you will get a directory listing of the root directory.
Telnet to the httpd port and type 'get/' to get a root directory listing.

Netscape FastTrack contains a flaw that allows a remote user to obtain a directory listing of files regardless of the presence of "index.html" (or similar default files). The issue is due to FastTrack not properly handling lower case web requests. By requesting a "get" instead of "GET", an attacker can bypass the displaying of default files and see a raw listing of files in a directory.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: Disable open browsing completely.
