RE: Device fingerprinting

If I had to guess, I would say BorderWare Firewall Server
(http://www.borderware.com/products/fw/fwserver.html). It has proxy support
for the protocols that use the open ports you found from the Internet and it
uses port 442 for management over HTTPS.

Cheers

Fernando

Hi list,

Recently I came against a weird network infrastructure. Can you help me
identify the types of devices used?

I have this:

[Internet]
----------------------
[An unknown device]
----------------------------------------
[Box 1-Webserver] [Box 2-Mailserver]

I was able to compromise the mailserver using web exploits.
Portscans of each devices from either the internet or the
mailserver yields
different results as shown above.

------------------
From the internet:
------------------
Unknown device:
     Open ports: 21,23,25,53,80,109,110,442
     Closed ports: 49400,54320,61439,61440,61441,65301
     Filtered: Everything else
     Replies to echo requests: No
     Nmap tcp fingerprint: FreeBSD 2.2.1 - 4.1, FreeBSD 4.1.1 - 4.3 (X86)

Webserver:
     Open ports: 21,80,3306
     Closed ports: 49400,54320,61439,61440,61441,65401
     Filtered: Everything else
     Replies to echo requests: No
     Nmap tcp fingerprint: FreeBSD 2.2.1 - 4.1, FreeBSD 4.1.1 - 4.3 (X86)

Mailserver:
     Open ports: 80,110
     Closed ports: None
     Filtered: Everything else
     Replies to echo requests: No
     Nmap tcp fingerprint: spcheck reports SP6 b1381
