Overview
WEB-300 is an advanced offensive security course designed for experienced penetration testers, focusing on deep analysis and exploitation of modern web application vulnerabilities
WEB-300 (Advanced Web Attacks and Exploitation) provides experienced offensive team members with a comprehensive analysis of various vulnerabilities and their exploitation techniques in web applications. Building on the PEN-200 and WEB-200 programs, this program will dig deep into the methodologies and techniques used to analyze the target web applications. This will give learners a complete understanding of the underlying flaws that we are going to exploit. The goal of this course is to expose you to a general and repeatable approach to web application vulnerability discovery and exploitation, while continuing to strengthen the foundational knowledge that is necessary when faced with modern-day web applications.
WEB-300 covers a wide range of advanced web exploitation skills and techniques, including:
- Analyzing and exploiting a deserialization remote code execution (RCE) vulnerability in the DotNetNuke (DNN) platform
- Mastering advanced web security methodologies such as fuzzing, static and dynamic analysis, and manual code review
- Practicing session hijacking techniques to gain unauthorized access to sensitive data and functionality, including exploiting an RCE vulnerability in the Dolibarr application using a dedicated virtual machine
WEB-300 is organized into 17 in-depth modules, each focusing on different topics. Many modules include companion videos and hands-on activities to reinforce the learning experience. Additionally, 20 Challenge Labs are provided to test learners' understanding and prepare them for the OffSec Web Expert (OWSE) certification exam.
As an advanced offensive course, WEB-300 is developed to test experienced penetration testers and security professionals seeking to master advanced web application attacks and exploitation techniques. It is expected that learners are not only familiar with basic web technologies and scripting languages, such as JavaScript, PHP, Java, and C#, but also have a high level of experience in offensive techniques taught in PEN-200.

Success stories from the field
I was able to use my dev background and combine it with everything I've been learning since I began with this dream a year ago. I spent countless hours studying, trying to absorb so many concepts, tools, strategies, techniques.What a ride so far.
I am officially OSWE-certified. So grateful to have had the opportunity to train for, take, and pass this certification. It was a fun one, and I'm happy to say it sharpened my skills as an AppSec engineer.
I am happy to announce that I passed OffSec's (in)famous 48-hour long exam and obtained the Offensive Security Web Expert (OSWE) certification. It is an excellent course. I'd recommend this to any full-stack developer who wants to get better at what they do. Thanks for a great course, Offensive Security!
Despite the large variances in extra miles, I recommend doing them. Some extra miles encourage the student to perform self-initiated research, often leading into new peripheral learning journeys.
