I am conducting a pen test on an application that
crosses our firewall - the app is well setup and
protected. Also we only allow port 80 and 443 to cross
the firewall.

While testing the app I was using the @stake web proxy
to alter the contents of the http data stream. With
the http "session" still fresh I changed the ns
browser (4.7) to no longer use the local proxy
127.0.0.1 and instead connect directly to the http
server that runs the app - then I simply hit enter.

I was suprised to get a netscape basic authentication
prompt box with the text

Enter Username for Netscape Entperprise Server at
199.999.99.99:80

Questions ?

1. Does the server owner have to setup any userids to
run this server or is there always a default admin
userid in place on these servers ?
2. The prompt box did not specify any userid - just
the text above. I think I can start password guessing
for the Netscape enterprise server administrator
userid. Any reason I cannot ?
3. Can this prompt be turned off - in other words why
is this prompt going out through the firewall - the
firewall permits only port 80 & 443 - ethereal shows
this traffic is port 80
4. I thought that the admin port for a NS 4.1 server
did not default to port 80 ??

I think that this prompt could be used for password
guessing on the server administrator userid - if the
server has such userid assigned. To me this is a
potential entry into the NS server across the firewall
via port 80 !!

I also found another means to get the same prompt -
making me suspect that the Netscape Server is
misconfigured.

Before I bring this to the attention of the server
admin can anyone answer any of the above questions ?

Reading the NS site docs does not conclusively tell me
that an administrator userid has to exist - and - does
not say (as far as I can find) if there is a way to
prevent this prompt from going out across the firewall
- there must be a way to prevent this in the Netscape
server

all help appreciated
