I recently did a scan of my internal network using NESSUS. It came up with some interesting results. Background on my network first:
2 - laptops
2 - desktops
1 - linksys NAS

If someone can decypher and explain to me what is mis-configured hopefully it would be appreciated.
----------------------------------------------------------------------------------------------------------
1)
http (80/tcp)


The remote proxy is vulnerable to format strings attacks
when issued a badly formed user name.

This flaw allows an attacker to execute arbitrary code on this
host.

Solution: if you are using NSM, see http://www.solsoft.org/nsm/news/972559672/index_html
or else contact your vendor for a patch

Risk Factor : High
Plugin ID : 10540

Synopsis :

The remote web server might transmit credentials over clear text

Description :

The remote web server contains several HTML forms containing
an input of type 'password' which transmit their information to
a remote web server over plain text.

An attacker eavesdropping the traffic might use this setup to
obtain logins and passwords of valid users.

----------------------------------------------------------------------------------------------------------
2)
https (443/tcp)

The remote system appears vulnerable to an invalid Options field
within a TCP packet. At least one vendor firewall (Symantec) has
been reported prone to such a bug. An attacker, utilizing this flaw,
would be able to remotely shut down the remote firewall (stopping all
network-based transactions) by sending a single packet to any port.

Risk Factor : High
CVE : CVE-2004-0375
BID : 10204
Other references : IAVA:2004-A-0010, OSVDB:5596
Plugin ID : 12216



I understand this is internal so these might be exceptable risks within a home environment. If someone has a little more understanding I to would like understand

Thanks

Which devices were generating the warnings? I'm guessing the Linksys box (since it probably has a WebGUI).

What would be more telling is running the scan from the UNTRUST port on the firewall (be careful doing it over the WAN since some ISP's check for port scan activity and have clauses in their terms of service agreements against it).

I'd also be interested in seeing what kind of warnings the Z100 comes back with when you run NESSUS against it. I don't have one yet, but I have a SNORT setup and it lights up like a Christmas tree when you run a scan.
