Introduction
</H2>
<P ALIGN=JUSTIFY>This document is a user guide for the Web
Application Attack and Audit Framework ( w3af ), its goal is to
provide a basic overview of what the framework is, how it works and
what you can do with it.
</P>
<P ALIGN=JUSTIFY>w3af is a complete environment for auditing and
attacking web applications. This environment provides a solid
platform for auditing and penetration-testing.

<H2 CLASS="western">Download</H2>
<P STYLE="margin-top: 0.17in"><FONT FACE="Bitstream Vera Sans, sans-serif">The
framework can be downloaded from the project main page: </FONT>

<P ALIGN=JUSTIFY STYLE="margin-top: 0.17in"><FONT FACE="Bitstream Vera Sans, sans-serif">There
are two ways to install w3af: from a release package (w3af setup for
windows and tgz package for Unix based systems) or from SVN. First
time users should use the latest package, while more advanced users
should perform a SVN checkout to get the latest version of the
framework. </FONT>

installing w3af in a Windows box is straight forward if you use the

site.</FONT></P>
<H3 CLASS="western" ALIGN=JUSTIFY STYLE="page-break-after: avoid">Installation
Requirements</H3>
<P>The required packages to run w3af can be divided in two groups:</P>
<UL>
<LI><P>Core requirements:</P>

<P ALIGN=JUSTIFY>As you may have guessed, the core requirements are
needed to run w3af with any user interface (console or graphical),
and the graphical user interface requirements are needed only if you
plan to use the GTK+ user interface.</P>
<P ALIGN=JUSTIFY>Some of the requirements are bundled with the
distribution file, in order to make the installation process easier
for the novice user. The bundled requirements can be found inside the
<I>extlib</I> directory. Most of the libraries can be run from<SPAN STYLE="font-style: normal">
that</SPAN> directory, but some others require an installation
process, the installation steps for these libraries are (as root):</P>

<P ALIGN=JUSTIFY>Before running w3af a user must know how the
application is divided and how plugins are going to be executed. The
framework has three types of plugins: discovery , audit and attack.</P>
<P ALIGN=JUSTIFY><I>Discovery plugins</I> have only one
responsibility, finding new URLs, forms, and other “injection
points”. A classic example of a discovery plugin is a web spider.
This plugin takes a URL as input and returns one or more injection
points. When a user enables more than one plugin of this type, they
work in a loop: If plugin A finds a new URL in the first run, the
w3af core will send that URL to plugin B. If plugin B then finds a
new URL, it will be sent to plugin A. This process will go on until
all plugins are run and no more knowledge about the application can
be found using the enabled discovery plugins.</P>
<P ALIGN=JUSTIFY><I>Audit plugins</I> take the injection points found
by discovery plugins and send specially crafted data to all of them
in order to find vulnerabilities. A classic example of an audit
plugin is one that searches for SQL injection vulnerabilities.</P>
<P ALIGN=JUSTIFY><I>Attack plugins </I><SPAN STYLE="font-style: normal">objective
is to exploit vulnerabilities found by audit plugins. They usually
return a shell on the remote server, or a dump of remote tables in
the case of SQL injections exploits.</SPAN></P>

<P ALIGN=JUSTIFY STYLE="font-style: normal">w3af has two user
interfaces, the console user interface (consoleUI) and the graphical
user interface (gtkUi). This user guide will focus on the consoleUI,
which ismore fully tested and complete than the gtkUi. To fire up the
consoleUI you just have to execute w3af without parameters and you
will get a prompt like this one:</P>

this prompt you will be able to configure the framework, launch scans
and ultimately exploit a vulnerability. At this prompt you can start
typing commands. The first command you have to learn is “help”

framework. All the parameters have defaults and in most cases you can
leave them as they are. w3af was designed in a way that allows
beginners to run it without having to learn a lot of its internals.
It is also flexible enough to be tuned by experts that know what they
want and need to change internal configuration parameters to fulfill
their tasks.</FONT></P>

<P><BR><BR>
</P>
<P ALIGN=JUSTIFY>Plugins do all the magic. The plugins will find the
URLs, discover the vulnerabilities and exploit them. So now, we will
learn how to configure the plugins. In a previous section it was
explained that w3af had three core types of plugins: discovery, audit
and exploit. The complete list of plugins types is:</P>
<P><BR><BR>
</P>
<UL>
<LI><P>discovery</P>
<LI><P>audit</P>
<LI><P>grep</P>
<LI><P>exploit</P>
<LI><P>output</P>
<LI><P>mangle</P>
<LI><P>bruteforce</P>
<LI><P>evasion</P>
</UL>
<P><BR><BR>
</P>
<P ALIGN=JUSTIFY>Discovery plugins find new points of injection that
are later used by audit plugins to find vulnerabilities. Grep plugins
analyze all page content and find vulnerabilities on pages that are
requested by other plugins; for example, a grep plugin will find a
comment on the HTML body that has the word “password” inside it
and generate a vulnerability based on it.</P>
<P ALIGN=JUSTIFY>Exploit plugins [ab]use the vulnerabilities found in
the audit phase and return something useful to the user ( remote
shell, SQL table dump, a proxy, etc ).</P>
<P ALIGN=JUSTIFY>Output plugins are the way the framework and the
plugins communicate with the user. Output plugins save the data to a
text or html file. Debugging information is also sent to the output
plugins and can be saved for analysis.</P>
<P ALIGN=JUSTIFY>Mangle plugins allow modification of requests and
responses based on regular expressions, think “sed (stream editor)
for the web”.</P>
<P ALIGN=JUSTIFY>Bruteforce plugins will bruteforce logins. These
plugins are part of the discovery phase.
</P>
<P ALIGN=JUSTIFY>Finally, evasion plugins try to evade simple
intrusion detection rules.</P>
<H3 CLASS="western"></H3>

<P>The discovery phase is a double edged sword: use it with wisdom,
and it will give you a lot of knowledge about the remote web
application, use it in a greedy way and you will be waiting for hours
until the discovery phase ends. Just to make things clear, the greedy
way is to enable all discovery plugins ( “discovery all” )
without even knowing what you are doing or having manually browsed
the web and understood its internals.

the addresses put in this site wont be available in search engines
because they never were indexed. BingSpider and googleSpider find
URLs using search engines, like the ones before, they are useless
because search engines don't index private pages. phishtank and
googleSafeBrowsing should be enabled because they search for
phishing sites, and like the ones before them, private sites aren't
indexed in this systems.</SPAN></P>

<P ALIGN=JUSTIFY>Some sites use embedded objects, like Macromedia
Flash and Java applets, that the browser renders to the user. Because
of the inability of the framework to get any information out of those
objects, a script called spiderMan was created. This script will run
a HTTP proxy so the user can navigate the target site through it;
during this process the plugin will extract information from the
requests and responses.</P>
<P ALIGN=JUSTIFY>A simple example will clarify things, let's suppose
that w3af is auditing a site and can't find any links on the main
page. After a closer interpretation of the results by the user, it is
clear that the main page has a Java applet menu where all the other
sections are linked. The user runs w3af once again and now activates
the spiderMan plugin, navigates the site manually using the browser
and the spiderman proxy. When the user has finished his browsing,
w3af will continue with all the hard auditing work.</P>
<P ALIGN=JUSTIFY>The spiderMan plugin can be used when Javascript,
Flash, Java applets or any other browser side technology is present.</P>

<P ALIGN=JUSTIFY>Nothing special for now, just added the new “<FONT FACE="Nimbus Mono L, monospace"><SPAN STYLE="font-weight: medium">start
vdaemon</SPAN></FONT>” command. With this w3af run we have covered
items 1. and 2. of the theory. The next step is to configure the MSF
module and run it; my preferred way is to use metasploit's web
interface “msfweb”. The first step is to click on the “Exploit”
button on the main menu. This will cause a small window to appear. In
this window, you should search for <I>w3af </I>and then select the
exploit named: “w3af virtual daemon exploit”. Some important
points to have in mind while configuring the w3af agent virtual
daemon module inside MSF:</P>
