Subject extra long URL attack

I'm pretty sure we deliberately fixed this bug as opposed to it just being
fixed by chance... but I thought I'd forward it anyhow.

Subject: extra long URL attack

I don't know about CGI attacks, but this extra long URL to
my site running
        Server version Stronghold/1.3 Ben-SSL/1.3 Apache/1.1.1.
will show you the raw contents of the top directory
rather than the /index.html file (using Netscape Navigator 3.0 solaris
for a browser).

i've always wondered how safe it was to count on nobody seeing
past your index.html -- now i know.  I wonder if some varient
will get you the root directory of my entire filesystem instead
of just the top directory of my web.  I knew I should have
chrooted this stuff....

You're was the only server (that I tried) that this worked on.  In particular,
it does not work against Apache/1.2bX sites, including:

        Server: Stronghold/2.0b1 Apache/1.2b2

This works also for standard Apache 1.1.1. One solution is to turn off
indexing in Apache config. In your access.conf file, in Options just
remove the word Indexes.

This doesn't seem to work with Apache 1.1.1 on my Linux 2.0.27 box or NCSA
httpd 1.5.2 on Digital UNIX v3.2 41 alpha.

Maybe its just the apache SSL extensions somehow?

I tried using Netscape 3.01 both ELF and Win32, lynx 2.5 (linux), lynx 2.6
(Digital unix) and MS Internet Explorer on NT.
