Wapiti Tool for web application security auditor



In order to work correctly, Wapiti needs :

  • Python 2.x where x is >= 6 (2.6, 2.7...)

  • python-requests v1.2.3 or more ( http://docs.python-requests.org/en/latest/ )

  • BeautifulSoup ( http://www.crummy.com/software/BeautifulSoup/ )

  • python-xml

How it works

Wapiti works as a "black-box" vulnerability scanner,  that means it won't

study the source code of web applications but will work like a  fuzzer,

scanning the pages of the deployed web application, extracting links and

forms  and attacking  the scripts, sending payloads and looking for error

messages, special strings or abnormal behaviors.

General features

  • Generates vulnerability reports in various formats (HTML, XML, JSON, TXT...)

  • Can suspend and resume a scan or an attack

  • Can give you colors in the terminal to highlight vulnerabilities

  • Different levels of verbosity

  • Fast and easy way to activate/deactivate attack modules

  • Adding a payload can be as easy as adding a line to a text file

Browsing features

  • Support HTTP and HTTPS proxies

  • Authentication via several methods : Basic, Digest, Kerberos or NTLM

  • Ability to restrain the scope of the scan (domain, folder, webpage)

  • Automatic removal of a parameter in URLs

  • Safeguards against scan endless-loops (max number of values for a parameter)

  • Possibility to set the first URLs to explore (even if not in scope)

  • Can exclude some URLs of the scan and attacks (eg: logout URL)

  • Import of cookies (get them with the wapiti-cookie and wapiti-getcookie tools)

  • Can activate / deactivate SSL certificates verification

  • Extract URLs from Flash SWF files

  • Try to extract URLs from javascript (very basic JS interpreter)

  • HTML5 aware (understand recent HTML tags)

Supported attacks

  • Database Injection (PHP/ASP/JSP SQL Injections and XPath Injections)
  • Cross Site Scripting (XSS) reflected and permanent
  • File disclosure detection (local and remote include, require, fopen, readfile...)
  • Command Execution detection (eval(), system(), passtru()...)
  • XXE (Xml eXternal Entity) injection
  • CRLF Injection
  • Search for potentially dangerous files on the server (thanks to the Nikto db)
  • Bypass of weak htaccess configurations
  • Search for copies (backup) of scripts on the server

Wapiti supports both GET and POST HTTP methods for attacks.

It also supports multipart and can inject payloads in filenames (upload).

Display a warning when an anomaly is found (for example 500 errors and timeouts)

Makes the difference  beetween permanent  and reflected  XSS vulnerabilities.

How to get the best results

To find more vulnerabilities (as some attacks are error-based), you can modify

your webserver configurations.

For example, you can set the following values in your PHP configuration :

safe_mode = Off

display_errors = On (recommended)

magic_quotes_gpc = Off

allow_url_fopen = On

mysql.trace_mode = On

Where to get help

In the prompt, just type the following command to get the basic usage :

python wapiti.py -h

You can also take a look at the manpage.
