Security Issues and Fixes:
Type Port Issue and Fix
Warning ssh (22/tcp)
The remote SSH daemon supports connections made
using the version 1.33 and/or 1.5 of the SSH protocol.

These protocols are not completely cryptographically
safe so they should not be used.

Solution :
If you use OpenSSH, set the option 'Protocol' to '2'
If you use's set the option 'Ssh1Compatibility' to 'no'

Risk factor : Low

Warning http (80/tcp)
The remote web server seems to have its default welcome page set.
It probably means that this server is not used at all.

Solution : Disable this service, as you do not use it
Risk factor : Low
Nessus ID : 11422
Informational http (80/tcp) A web server is running on this port
Nessus ID : 10330
Informational http (80/tcp) The following directories were discovered:
/cgi-bin, /icons, /manual

While this is not, in and of itself, a bug, you should manually inspect
these directories to ensure that they are in compliance with company
security standards

Nessus ID : 11032
Informational http (80/tcp) The remote web server type is :

Apache/1.3.29 (Darwin)

Solution : You can set the directive 'ServerTokens Prod' to limit
the information emanating from the server in its response headers.
Nessus ID : 10107
Informational http (80/tcp) An information leak occurs on Apache based web servers
whenever the UserDir module is enabled. The vulnerability allows an external
attacker to enumerate existing accounts by requesting access to their home
directory and monitoring the response.

1) Disable this feature by changing 'UserDir public_html' (or whatever) to
'UserDir disabled'.


2) Use a RedirectMatch rewrite rule under Apache -- this works even if there
is no such entry in the password file, e.g.:
RedirectMatch ^/~(.*)$$1


3) Add into httpd.conf:
ErrorDocument 404 http://localhost/sample.html
ErrorDocument 403 http://localhost/sample.html
(NOTE: You need to use a FQDN inside the URL for it to work properly).

Warning netbios-ssn (139/tcp) The host Security Identifier (SID) can be obtained remotely. Its value is :

OSX-HONEYPOT : 5-21-2048677180-2056306105--336065392

An attacker can use it to obtain the list of the local users of this host
Solution : filter the ports 137-139 and 445
Risk factor : Low

CVE : CVE-2000-1200
BID : 959
Nessus ID : 10859
Warning netbios-ssn (139/tcp) The host SID could be used to enumerate the names of the local users
of this host.
(we only enumerated users name whose ID is between 1000 and 1200
for performance reasons)
This gives extra knowledge to an attacker, which
is not a good thing :

Informational netbios-ssn (139/tcp) An SMB server is running on this port
Nessus ID : 11011
Informational netbios-ssn (139/tcp)
It was possible to log into the remote host using a NULL session.
The concept of a NULL session is to provide a null username and
a null password, which grants the user the 'guest' access

To prevent null sessions, see MS KB Article Q143474 (NT 4.0) and
Q246261 (Windows 2000).
Note that this won't completely disable null sessions, but will
prevent them from connecting to IPC$

Warning ipp (631/tcp)
It seems that your web server tries to hide its version
or name, which is a good thing.
However, using a special crafted request, Nessus was able
to determine that is is running :

Risk factor : None
Solution : Fix your configuration.
Nessus ID : 11239
Warning ipp (631/tcp)
Some Web Servers use a file called /robot(s).txt to make search engines and
any other indexing tools visit their WebPages more frequently and
more efficiently.

By connecting to the server and requesting the /robot(s).txt file, an
attacker may gain additional information about the system they are

Such information as, restricted directories, hidden directories, cgi script
directories and etc. Take special care not to tell the robots not to index
sensitive directories, since this tells attackers exactly which of your
directories are sensitive.

The file 'robots.txt' contains the following:
# "$Id: robots.txt,v 2003/04/11 21:07:24 jlovell Exp $"

Informational ipp (631/tcp) A web server is running on this port
Nessus ID : 10330
Informational ipp (631/tcp) The following CGI have been discovered :

Syntax : cginame (arguments [default value])

/admin/ (op [add-class] )
/jobs (which_jobs [completed] )

Nessus ID : 10662
Informational ipp (631/tcp) The remote web server type is :


Solution : We recommend that you configure (if possible) your web server to return
a bogus Server header in order to not leak information.

Nessus ID : 10107
Informational ipp (631/tcp) The following PDF files (.pdf) are available on the remote server :

You should make sure that none of these files contain confidential or
otherwise sensitive information.

An attacker may use these files to gain a more intimate knowledge of
your organization and eventually use them do perform social engineering
attacks (abusing the trust of the personnel of your company).

Solution : sensitive files should not be accessible by everyone, but only
by authenticated users.
Nessus ID : 11419
Informational ntp (123/udp) It is possible to determine a lot of information about the remote host
by querying the NTP (Network Time Protocol) variables - these include
OS descriptor, and time settings.

It was possible to gather the following information from the remote NTP host :

version='ntpd 4.1.1@1.786 Fri Sep 12 18:30:03 PDT 2003 (1)',
processor='Power Macintosh', system='Darwin7.5.0', leap=3, stratum=16,
precision=-18, rootdelay=0.000, rootdispersion=1.125, peer=0,
refid=, reftime=0x00000000.00000000, poll=4,
clock=0xc4e0ff1a.a535b91f, state=0, offset=0.000, frequency=0.000,
jitter=0.004, stability=0.000

Quickfix: Set NTP to restrict default access to ignore all info packets:
restrict default ignore

Risk factor : Low
Nessus ID : 10884
Informational general/icmp Here is the route recorded between and :

Nessus ID : 12264
Informational unknown (5353/udp)
The remote host is running the RendezVous (also known as ZeroConf or mDNS)

This protocol allows anyone to dig information from the remote host, such
as its operating system type and exact version, its hostname, and the list
of services it is running.

We could extract the following information :

Computer name : OSX-HoneyPot
Ethernet addr : 00:0d:93:c0:f2:ac
Computer Type : PowerBook6,4
Operating System : Mac OS X 10.3.5

Solution : You should filter incoming traffic to this port if you do not use
this protocol.

Risk Factor : Low
Nessus ID : 12218
Informational general/udp For your information, here is the traceroute to :

Nessus ID : 10287
Warning general/tcp
The remote host might be vulnerable to a sequence number approximation
bug, which may allow an attacker to send spoofed RST packets to the remote
host and close established connections.

This may cause problems for some dedicated services (BGP, a VPN over
TCP, etc...).

Solution : See
Risk factor : Medium
CVE : CAN-2004-0230
BID : 10183
Other references : OSVDB:4030, IAVA:2004-A-0007
Nessus ID : 12213
Informational general/tcp The remote host is running Mac OS X 10.3.5
Nessus ID : 11936
Warning netbios-ns (137/udp) The following 5 NetBIOS names have been gathered :
OSX-HONEYPOT = This is the computer name registered for workstation services by a WINS client.
OSX-HONEYPOT = This is the current logged in user registered for this workstation.
OSX-HONEYPOT = Computer name
WORKGROUP = Workgroup / Domain name
WORKGROUP = Workgroup / Domain name (part of the Browser elections)

. This SMB server seems to be a SAMBA server (this is not a security
risk, this is for your information). This can be told because this server
claims to have a null MAC address

If you do not want to allow everyone to find the NetBios name
of your computer, you should filter incoming traffic to this port.

Risk factor : Medium
