Re: Vulnerability discovered on Lotus Domino server "admin4.nsf"

Subject: Re: Vulnerability discovered on Lotus Domino server "admin4.nsf"

From what I've gathered, it would appear that Lotus is aware that "admin4.nsf" is accessible by unauthenticated users. A Google search revealed that the L0pht team discovered a vulnerability in Domino that lets unauthenticated users view admin4.nsf.
In addition to this, it also looks like you can change the file's data and potentially alter the site's intended behavior. If the site hasn't prohibited directory browsing, you should also be able to view the directory with the command "http://www.example.com/?open"; and view the admin4.nsf file with "http://example.com/admin4.nsf"; and get some useful information from there.


Hope this helps.

Hi,

I'm doing an external blackbox PT on a mail server running Lotus
Domino. The server OS is Windows 2000 and web server is Lotus Domino.
It has following ports open:

80 - Lotus Domino httpd
443 - Lotus Domino httpd
1352 - Lotus Domino server
5631 - PCAnywhere

During a manual assessment I discovered "admin4.nsf" on server,
accessible without any sort of authentication.  It is suppose to be
the Administrator Request Database. From the name I suppose this
should be something that shouldn't be visible to everyone. I don't
have any experience in Lotus Domino. I read a couple of docs on
Internet but couldn't get the real implication of such a
vulnerability. I'm a little hesitant to perform any actions with the
interface as it might disrupt some activities on the server and client
might not like it.

Is there anybody on the list who could guide me on the implication of
this vulnerability and how to get a proper sense of it. What are the
functionalities of 'admin4.nsf' and what damage could it do if an
un-authenticated user has access to it.

Looking forward to some enlightenment on this topic.

Now I'm going to downlaod a Lotus client and see what I can do with
the other open port "1352", looks like another hole from where I can
find my way in.

Thank you.
