OWASP Zed Attack ProxyFADI ABDULWAHAB FABDULWAHAB.COM

Overview

https://www.owasp.org/index.php/OWASP_Zed_Attack_Proxy_Project Pen Testing tool for web applications Easy to install (required Java as prerequisites) Free and open source (World contribution) Ideal for beginners and professionals Support automation Cross platform(Windows , Linux and Mac) Fully documented and Integrated with other tools

Overview

Intercepting tool Active /Passive scanning Spider to crawl the site (also support Ajax spider for heavy JavaScript applications) Report Generation with useful information and recommendation Brute force (based on OWASP DirBuster tool)

https://www.owasp.org/index.php/Category:OWASP_DirBuster_Project It is now included in the ZAP Marketplace as a ZAP add-on rather than as a stand-alone tool to brute force directories and files names on web/application servers

Fuzzing (using fuzzdb and OWASP JBroFuzz) https://github.com/fuzzdb-project/fuzzdb https://www.owasp.org/index.php/JBroFuzz

Overview

Auto tagging (hidden filed , cookie …) Port scanning Parameters analysis Support Web socket

http://browserquest.mozilla.org/ Support HTTP Sessions Has REST API (Tools >> Browse API) Has Dynamic SSL certificate to generate root certificate for browsers Support Anti-CSRF token Framework for other tools

Overview

Quick Test No authentication Spider not covering everything

Add extensions/update as marketplace (Add-ons) Debug and breakpoints Support Context(Scopes)

Exclude/Include URLs Authentication

Modes Safe (passive), Protected(within scope) and Standard

You can scan Subtree only

Overview

You can write Java or python codes ZAP embedded into ThreadFix (Denim Group) and Minion (Mozilla) Integrated with Firefox as Plug-in-Hack Intercept client side GET/POST requests Use less memory and has minimum false positive risks

Installation and Configuration

Download it Install it Configure browser proxy (local proxy)

Run ZAP Browser your application manually (No one know the application functionalities

like you) Use spider for more hidden content (beside manual browsing also find logical

tests) Run Attacks to find vulnerabilities

Initial Setup

Configure Proxy(Options >> Local Proxy…) Import SSL certificate (.cer) to certificate manger in your browser if you

need to intercept SSL websites (Options >> Dynamic SSL…) chrome://settings/search#ssl

Open Sites Tab to view resources which have been visited Check Request/Response Vulnerable Site https://github.com/psiinon/bodgeit

Security Testing in Dev and QA

Consider security in all phases of project It’s a risk to postpone this testing at the end of project lifecycle Most important phases are Dev and QA Beside testing functionality test also inject ZAP for security Test https://github.com/zaproxy/zaproxy/wiki/SecRegTests

Security Testing in Dev and QA

Authentication

Context A set of URLs together Good to Categories your web applications

Session Management Cookie based HTTP Header based

Authentication methods Form , HTTP Header or oAuth authentication

User Management Define users and map them to HTTP sessions

HTTP Sessions

Browser your site with different accounts All sessions are recorded to HTTP Session tab You can switch between them using “Set as active”

Refresh the page after switching the session Flag login page (username , password and indicators for login and

logout) Then click resend

HTTP Sessions

Demo Browse the site anonymously Login from the browser

Go to login page and flag as Context Define Username , passwords

Create Users Spider the site as User

HTTP Sessions

This force ZAP to login again Try to resend a page after removing session cookie from header You can add session manually

HTTP Sessions

With Ajax site , maybe the session is not recorded You can identify it manually

Right click and Flag as Session token Right click and make it active Then logout from the site and login again

Sometime you need to exclude logout page to avoid session termination

Attacks and Attacks Strength

You can control the attacks and attacks strength

Statistics – ZAP Innovations

Zest

Scripting language developed by Mozilla team Free and open source Represent JSON Included with ZAP from 2.0

Fuzzing

Highlight the text (user input/parameters) Select Fuzz category Run it and see the browser You can use multiple fuzz payloads

Injection

Highlight the found text You can get information from failed requests Also use your patterns

Hashing and New UI

Included with ZAP

New UI: Hide or Show all tabs (also advanced options) You can add note and use filter in history tab Persistent Session to resume your work Define Scan policy to control the attacks

Don’t stick with one tool , use more because each one has its advantages
