Description

The access to this course is restricted to Hakin9 Premium or IT Pack Premium Subscription

Nowadays, the number of web application firewalls (or simply WAFs) is increasing, which results in a more difficult penetration test from our side. So, it becomes a necessity and really important to be able to bypass WAFs in a penetration test. In this course, we are going to examine practical approaches in bypassing WAFs as a part of our penetration test, and, of course, the theory behind WAFs and how they work.

18 CPE Credits

Syllabus


Module 1

Introduction WAFs, WAF Bypassing and techniques

In this module, we will quickly examine how WAFs work in a web server, and we will be introduced to WAF Bypassing and some interesting methods with practical examples, attacking web application firewalls with conventional methods.

    1. Introduction to WAFs, WAF types and WAF Bypassing
    2. WAF Fingerprinting
    3. Automating WAF Fingerprinting with Burp, Nmap and wafw00f
    4. WAF Bypassing

Exercises:

    1. Fingerprinting a WAF with Burp Suite. 
    2. Using automated tools for testing
    3. Polluting a URL
    4. Bypassing the WAF in DVWA

Module 2

WAF Bypassing with SQL Injection

In module 2, we examine how we can bypass WAF by exploiting SQL Injection vulnerabilities, with various ways such as normalization and HTTP Parameter Pollution.

    1. HTTP Parameter Pollution – HPP
    2. Encoding Techniques for Bypassing WAF
    3. Bypassing WAF with SQL Injection
    4. HTTP Parameter Fragmentation – HPF
    5. Bypassing WAFs with SQL Injection Normalization
    6. Buffer Overflow + SQL Injection = Bypass WAF

Exercises: 

    1. Bypassing WAF with encoded queries
    2. Advanced Techniques for blind SQL injection
    3. Blind SQL Injection Example in DVWA
    4. HPP and HPF vulnerable websites

Module 3

WAF Bypassing with XSS and RFI

In module 3, we will examine more ways of WAF Bypassing, this time containing the Remote File Inclusion and the Cross-Site Scripting and more.

    1.  Cross Site Scripting – XSS
    2. Reflected Cross Site Scripting
    3. Stored Cross-site Scripting
    4. Path Traversal
    5. Remote and Local File Inclusion

Exercises: 

    1. Encoded XSS strings
    2. Advanced XSS Examples
    3. Upload Example from DVWA exloitation
    4. Path traversal attacks

Module 4

Securing WAF and Conclusion

Finally, in module 4, we will see some final methods for bypassing WAFs, and prevention methods with practical examples for our WAF implementations.

  • DOM Based XSS
  • Bypassing Blacklists with JavaScript
  • Automating WAF Bypassing
  • Bypassing WAF Practical Examples ( Imperva WAF, Aqtronix WebKnight WAF, ModSecurity WAF, and others)
  • Conclusion and final exam

Frequently Asked Questions

  1. Will the course discuss how to identify which technique is best suited for each identified firewall?
    Yes.
  2. Will they be discussing the layers in the Application Server? The Web app? The database server?
    Yes.
  3. Will the course discuss binary and Hex encoding to bypass?
    Yes.
  4. Will the course discuss any of the CLI tools used by penetration testers to bypass WAFs?
    Yes.
  5. Is the course demonstrating how to bypass commercial grade or open source WAF?
    Both, but I may not reveal each WAF that I will test, because of copyrights.
  6. Is the course demonstrating how to bypass WAF with default or extensive configuration
    If the time allows it, in each case.
