Issue and Fix

Warning

netbios-ns (137/udp)

. The following 7 NetBIOS names have been gathered :
TESTSP3
WORKGROUP
TESTSP3
WORKGROUP
TESTSP3
INet~Services
IS~TESTSP3
. The remote host has the following MAC address on its adapter :
0x00 0x06 0x5b 0x14 0xc6 0xd5

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

Vulnerability

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$

. All the smb tests will be done as ''/'' in domain

Warning

netbios-ssn (139/tcp)

The domain SID can be obtained remotely. Its value is :

WORKGROUP : 48-0-0-0-0

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

CVE : CVE-2000-1200

Warning

netbios-ssn (139/tcp)

The host SID can be obtained remotely. Its value is :

TESTSP3 : 5-21-682003330-1677128483-1343024091

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

CVE : CVE-2000-1200

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 :
- Administrator account name : Administrator (id 500)
- Guest account name : Guest (id 501)
- TsInternetUser (id 1000)
- IUSR_TESTSP3 (id 1001)
- IWAM_TESTSP3 (id 1002)

Risk factor : Medium
Solution : filter incoming connections to port 139

CVE : CVE-2000-1200

Warning

netbios-ssn (139/tcp)

The following local accounts have never changed their password :

TsInternetUser
IUSR_TESTSP3
IWAM_TESTSP3


To minimize the risk of break-in, users should
change their password regularly

Warning

netbios-ssn (139/tcp)

The following local accounts have never logged in :

Guest
TsInternetUser


Unused accounts are very helpful to hacker
Solution : suppress these accounts
Risk factor : Medium

Warning

netbios-ssn (139/tcp)

The following local accounts have passwords which never expire :

Administrator
Guest
TsInternetUser
IUSR_TESTSP3
IWAM_TESTSP3


Password should have a limited lifetime
Solution : disable password non-expiry
Risk factor : Medium

Informational

netbios-ssn (139/tcp)

The remote native lan manager is : Windows 2000 LAN Manager
The remote Operating System is : Windows 5.0
The remote SMB Domain Name is : WORKGROUP

Informational

netbios-ssn (139/tcp)

The following local accounts are disabled :

Guest


To minimize the risk of break-in, permanently disabled accounts
should be deleted
Risk factor : Low

Vulnerability

http (80/tcp)


The IIS server appears to have the .HTR ISAPI filter mapped.

At least one remote vulnerability has been discovered for the .HTR
filter. This is detailed in Microsoft Advisory
MS02-018, and gives remote SYSTEM level access to the web server.

It is recommended that even if you have patched this vulnerability that
you unmap the .HTR extension, and any other unused ISAPI extensions
if they are not required for the operation of your site.

Solution:
To unmap the .HTR extension:
1.Open Internet Services Manager.
2.Right-click the Web server choose Properties from the context menu.
3.Master Properties
4.Select WWW Service -> Edit -> HomeDirectory -> Configuration
and remove the reference to .htr from the list.

Risk factor : High

Vulnerability

http (80/tcp)


The IIS server appears to have the .SHTML ISAPI filter mapped.

At least one remote vulnerability has been discovered for the
.SHTML filter. This is detailed in Microsoft Advisory MS02-018
and results in a denial of service access to the web server.

It is recommended that even if you have patched this vulnerability that
you unmap the .SHTML extension, and any other unused ISAPI extensions
if they are not required for the operation of your site.

An attacker may use this flaw to prevent the remote service
from working properly.

*** Nessus reports this vulnerability using only
*** information that was gatherered. Use caution
*** when testing without safe checks enabled

Solution: See
http://www.microsoft.com/technet/security/bulletin/ms02-018.asp
and/or unmap the shtml/shtm isapi filters.

To unmap the .shtml extension:
1.Open Internet Services Manager.
2.Right-click the Web server choose Properties from the context menu.
3.Master Properties
4.Select WWW Service -> Edit -> HomeDirectory -> Configuration
and remove the reference to .shtml/shtm and sht from the list.

Risk factor : Medium
CVE : CAN-2002-0072

Vulnerability

http (80/tcp)


The PROPFIND method is enabled on the remote IIS server.
On unpatched versions of IIS this allows anyone to
remotely shut this server down. Microsoft included this
patch in Win2k Service Pack 2.

*** Nessus reports this vulnerability using only
*** information that was gathered. Use caution
*** when testing without safe checks enabled.

Solution : disable the WebDAV extensions, as well as the PROPFIND
command See
http://support.microsoft.com/support/kb/articles/Q241/5/20.ASP
also:
http://www.microsoft.com/technet/security/bulletin/MS01-016.asp
Risk factor : Serious
CVE : CVE-2001-0151

Warning

http (80/tcp)


The remote web server appears to be running with
Frontpage extensions.

You should double check the configuration since
a lot of security problems have been found with
FrontPage when the configuration file is
not well set up.

Risk factor : High if your configuration file is
not well set up
CVE : CAN-2000-0114

Warning

http (80/tcp)


IIS 5 has support for the Internet Printing Protocol(IPP), which is
enabled in a default install. The protocol is implemented in IIS5 as an
ISAPI extension. At least one security problem (a buffer overflow)
has been found with that extension in the past, so we recommend
you disable it if you do not use this functionality.

Solution:
To unmap the .printer extension:
1.Open Internet Services Manager.
2.Right-click the Web server choose Properties from the context menu.
3.Master Properties
4.Select WWW Service -> Edit -> HomeDirectory -> Configuration
and remove the reference to .printer from the list.

Risk factor : Low

Warning

http (80/tcp)


IIS web server may allow remote users to read sensitive information
from .cnf files.

Example, http://target/_vti_pvt%5csvcacl.cnf

Solution: If you do not need .cnf files, then delete them, otherwise use
suitable access control lists to ensure that the .cnf files are not
world-readable. The files found on the server are as follows: /_vti_pvt%5caccess.cnf
/_vti_pvt%5csvcacl.cnf
/_vti_pvt%5cwriteto.cnf
/_vti_pvt%5cservice.cnf
/_vti_pvt%5cservices.cnf was found on web server.
.cnf files can give away confidential information regarding server configurationRisk factor : Medium

Warning

http (80/tcp)


The IIS server appears to have the .IDA ISAPI filter mapped.

At least one remote vulnerability has been discovered for the .IDA
(indexing service) filter. This is detailed in Microsoft Advisory
MS01-033, and gives remote SYSTEM level access to the web server.

It is recommended that even if you have patched this vulnerability that
you unmap the .IDA extension, and any other unused ISAPI extensions
if they are not required for the operation of your site.

Solution:
To unmap the .IDA extension:
1.Open Internet Services Manager.
2.Right-click the Web server choose Properties from the context menu.
3.Master Properties
4.Select WWW Service -> Edit -> HomeDirectory -> Configuration
and remove the reference to .ida from the list.

Risk factor : Medium
CVE : CAN-2002-0071

Warning

general/icmp


The remote host answers to an ICMP timestamp
request. This allows an attacker to know the
date which is set on your machine.

This may help him to defeat all your
time based authentication protocols.

Solution : filter out the ICMP timestamp
requests (13), and the outgoing ICMP
timestamp replies (14).

Warning

general/tcp


The remote host uses non-random IP IDs, that is, it is
possible to predict the next value of the
ip_id field of
the ip packets sent by this host.

An attacker may use this feature to determine if the remote
host sent a packet in reply to another request. This may be
used for portscanning and other things.
