OffSec AWAE/OSWE Review — 2026

Introduction

Good day! My name is Mason Schmidt, and I would like to share my experience with the OffSec Advanced Web Attacks and Exploitation (AWAE) course and the OffSec Web Expert (OSWE) certification exam. Before diving into the course itself, I believe it’s helpful to provide some background on my professional experience, as understanding the expected skill level is important for anyone considering this path.

I have worked in cybersecurity and penetration testing for nearly a decade, with a strong foundation in networking and general IT. I currently serve as a Senior Penetration Tester, where the majority of my work focuses on assessing complex, enterprise-grade web applications. In addition, I am comfortable reading and writing code in several languages, including Python, C#, and JavaScript.

This background aligned well with the expectations of the AWAE course and OSWE exam. Both require a solid understanding of application logic, the ability to review source code, and the capability to develop proof-of-concept exploits — ideally using a scripting language such as Python. For those who already possess these skills, the course is an appropriate next step. For those who do not, I strongly recommend investing time in learning how to analyze application code and automate tasks through scripting before attempting the course.

With that context in mind, I’ll move into a detailed discussion of my experience with the training and examination.

Course Overview

WEB-300 is designed for experienced offensive security professionals seeking a deep technical understanding of modern web application vulnerabilities and exploitation techniques. Building upon the foundational concepts introduced in PEN-200 and WEB-200, the course emphasizes methodology-driven testing, source code analysis, and real-world exploitation workflows.

The primary objective is to develop a repeatable and systematic approach to discovering and exploiting complex web vulnerabilities while strengthening core application security fundamentals.

Key Topics and Skills Covered

Web Application Analysis & Methodology

• Web security tools and techniques including:
• Fuzzing
• Static analysis
• Dynamic analysis
• Manual code review
• Source code analysis for identifying application logic flaws and attack vectors

Advanced Vulnerability Discovery & Exploitation

• JavaScript Prototype Pollution
• Advanced Server-Side Request Forgery (SSRF)
• Persistent Cross-Site Scripting (XSS)
• DOM-Based XSS (Black Box)
• Session Hijacking
• Server-Side Template Injection (SSTI)

Injection Attacks & Data Exploitation

• Blind SQL Injection
• Data exfiltration through SQLi, XXE, and file uploads
• XML External Entity (XXE) Injection

Overall Takeaway

WEB-300 focuses heavily on application internals, logic-based vulnerabilities, and real-world exploitation. Rather than relying on automated tooling, the course emphasizes manual analysis, custom proof-of-concept development, and attacker-style thinking — making it particularly valuable for penetration testers working with modern enterprise web applications.

Course Experience

Because I work full time, I opted for the Learn One (1-year) subscription to give myself the flexibility needed to properly absorb the material and prepare for the OSWE exam. The extended access removed unnecessary pressure and allowed me to study at a sustainable pace. In hindsight, given my experience level, I likely could have completed the course within the standard 90-day access window. However, the additional time provided peace of mind and flexibility, which I found valuable.

Overall, I felt the course material effectively builds the mindset and methodology required to pass the exam. The emphasis is less about memorizing techniques and more about developing a structured approach to analyzing applications, identifying vulnerabilities, and determining exploitability.

Initial Difficulty Curve

The first few chapters — particularly the ManageEngine and DotNetNuke (DNN) case studies — were intense. At times, it felt like drinking from a fire hose. There is a significant amount of technical detail introduced early on, and it requires careful attention.

That said, once past the initial ramp-up, the remainder of the material is presented in a much more digestible and structured format.

Real-World Case Study Approach

One of the strengths of the course is its use of real-world case studies. Rather than presenting isolated vulnerabilities in a vacuum, the material walks through realistic applications similar to what you might encounter in enterprise client environments. This reinforces:

• How vulnerabilities are discovered in practice
• How to trace application logic through source code
• How subtle flaws become exploitable under the right conditions

The labs further reinforce this learning and align closely with the exam expectations.

Mindset Over Memorization

At times, the material can feel overwhelming. However, the key takeaway is not memorizing payloads — it’s building the mindset to:

• Methodically review code
• Trace execution paths in an organized manner
• Identify where trust boundaries break down
• Differentiate between a benign coding issue and a truly exploitable vulnerability

That distinction becomes critical during the exam.

Study Methodology That Worked for Me

One approach that significantly helped me was:

1. Watching the videos first
2. Then working through the written material

The videos provided a high-level conceptual understanding before diving into the deeper technical details in the text. They also contain practical insights and small nuances that are not always emphasized in the written content.

Additionally, when developing proof-of-concept exploits, I chose to write scripts in the style and structure I was most comfortable with rather than strictly following the provided snippets. This reinforced foundational exploit development concepts and helped solidify muscle memory.

By the time I sat for the exam, writing exploit scripts felt almost automatic — which allowed me to focus more on analysis and problem-solving rather than syntax or structure.

Overall Impression

In my experience, the course material does a strong job of preparing learners for the labs, and the labs do an excellent job of reinforcing the skills required for the exam. The progression from concept → case study → lab work feels intentional and effective.

Challenge Labs — The Most Valuable Part of the Course

Without question, the part I enjoyed most throughout the entire process was the Challenge Labs included in the learning package.

At the time I completed the course, there were seven unique applications. Each was intentionally structured to reinforce the concepts taught throughout the material while also preparing you for the realities of the OSWE exam. The labs focused on the core attack paths covered in the course — ranging from SQL injection to command injection over WebSockets — but they were not straightforward, copy-and-paste exercises. Each lab introduced variations and subtle twists that forced you to truly understand what you were doing.

More importantly, several of the labs required chaining multiple vulnerabilities together in order to achieve authentication bypass and ultimately remote code execution (RCE). In my opinion, this is absolutely key for the OSWE exam.

Identifying a vulnerability in isolation is one thing. Chaining multiple vulnerabilities together in a reliable and repeatable way is another.

That distinction becomes critical.

My Lab Methodology

I approached every Challenge Lab using the same structured process I later used during the exam.

1. Initial Application Review (Black-Box Mindset) I would begin by interacting with the application without immediately diving into the source code. My goal was to identify potential sources and sinks — areas where user input entered the system and where that input was processed or executed.
2. Targeted Source Code Review Once I had a sense of the attack surface, I shifted to reviewing the source code, focusing specifically on the areas I had already identified. This made the review process much more intentional and efficient rather than randomly reading through thousands of lines of code.
3. Vulnerability Validation on the Debug System When I believed I had identified a vulnerability, I validated it against the provided “debug” version of the application. This environment was extremely helpful for testing assumptions and understanding execution flow.
4. POC Development and Automation After validating the issue, I would script that portion directly into my proof-of-concept exploit and test it against the target instance.

I took automation very seriously.

My goal was to build fully automated exploit scripts that completed the challenge from start to finish without any user interaction. That meant:

• Automatically handling authentication bypass
• Automatically delivering payloads
• Hosting required files via temporary HTTP servers
• Spawning reverse shells
• Even running automated post-exploitation enumeration commands on connection

I intentionally removed manual steps wherever possible.

This discipline paid off significantly during the exam. When time is limited, having a reliable, automated workflow makes a major difference.

Lab Structure and Difficulty

Overall, I felt the Challenge Labs did an excellent job reinforcing the learning objectives while pushing students to adopt the “Try Harder” mindset OffSec is known for.

The difficulty level was appropriate for the material being taught. They were challenging, but fair. If you understood the concepts and applied a structured approach, progress was achievable.

One aspect I particularly appreciated was the inclusion of both a debug and target version of each application. The setup required was minimal, which allowed me to focus on vulnerability discovery and exploitation rather than fighting environment configuration issues.

One Minor Criticism

My only real criticism was that one of the labs was entirely black-box, with no source code provided.

While black-box skills are obviously valuable in real-world testing, the OSWE exam is fully white-box — complete source code is provided. Given that, I felt this was a missed opportunity to deepen source code analysis skills instead of shifting focus to black-box enumeration.

That said, it was a minor issue in an otherwise strong lab experience.

Community and Support

Another underrated aspect of the labs was access to the course Discord channel. Students and mentors actively collaborate, discuss troubleshooting issues, and help clarify misunderstandings.

Personally, I only referenced Discord a few times — mostly when I thought something might be broken or when I needed clarification around setup behavior. I made a conscious effort to avoid over-relying on hints, but it was reassuring to know the community was there if needed.

Final Thoughts on the Challenge Labs

The Challenge Labs were, in my opinion, the bridge between learning the concepts and being ready for the exam.

They reinforced:

• Methodical source code analysis
• Vulnerability chaining
• Exploit automation
• Clean, structured POC development
• Persistence when progress stalls

More than anything, they forced me to think like an attacker working with full application visibility — which is exactly what the OSWE exam demands.

If someone asked me what part of the course best prepares you for the exam, my answer would be simple:

Take the Challenge Labs seriously — and automate everything.

OSWE Exam Overview

The OSWE exam is a 47 hour and 45 minute practical assessment, followed by an additional 24 hours to submit a professional-grade penetration test report. It is not simply a “find the flag” challenge — it is a full simulation of a white-box web application assessment under time constraints.

The exam is remotely proctored. A proctoring service connects to your system via screen sharing and monitors the session for the duration of the exam. Once the clock starts, it does not stop.

Exam Objectives

To pass the OSWE exam, you must:

• Obtain a total of 85 points.
• 35 points for each successful authentication bypass
• 15 points for each achieving remote code execution (RCE)
• Submit each flag to the exam control panel
• Document every step taken in a detailed, professional-grade penetration test report
• Provide fully automated exploit code that requires zero user interaction

That last requirement is important.

It is not enough to demonstrate exploitation manually. You must provide exploit code that:

• Executes from start to finish autonomously
• Reproduces authentication bypass
• Achieves RCE
• Requires no manual intervention
• Can be run directly by the examiner to validate the findings

In many ways, the automation requirement is what separates this exam from many other practical certifications.

Reporting Requirements

After the 47 hour and 45 minute exam window closes, you have 24 additional hours to complete and submit your report.

The report must clearly and professionally document:

• The vulnerabilities identified
• Detailed reproduction steps
• Technical explanation of root cause
• Impact assessment
• Fully automated proof-of-concept exploit code

The grading is based not only on technical success but also on clarity, accuracy, and professionalism in reporting. This portion of the exam reinforces that OSWE is meant to reflect real-world consulting work — not just technical exploitation ability.

White-Box Focus

Unlike many penetration testing exams, OSWE is 100% white-box. Full source code is provided for the applications under test. Success depends heavily on:

• Methodical source code review
• Identifying sources and sinks
• Tracing execution flow
• Understanding application logic
• Recognizing subtle implementation flaws

Brute-forcing or relying solely on dynamic testing will not get you far. Structured analysis is critical.

Overall Assessment

The OSWE exam is demanding, but fair.

It tests more than just technical knowledge — it evaluates:

• Discipline in methodology
• Efficiency under time constraints
• Ability to chain vulnerabilities
• Exploit automation skills
• Professional reporting ability

For anyone considering the exam, I strongly recommend practicing fully automated exploitation workflows ahead of time. Treat every lab like an exam scenario. Remove manual steps wherever possible. Build clean, repeatable exploit scripts.

That preparation makes a significant difference once the timer starts.

The OSWE Exam — My Personal Experience

Now for the part you’ve probably been waiting for — the exam review.

Needless to say, I will not be sharing any exam-specific technical details.

I scheduled my exam to begin at 7:00 PM on January 9th, 2026, which meant the check-in process opened at 6:45 PM. This was my third OffSec exam, so I was already familiar with the remote proctoring process and requirements.

What I failed to do — and learned the hard way — was check my equipment beforehand.

I connected right at 6:45 PM only to discover that the external webcam I had previously used (including during my OSEP exam) was no longer functioning properly with the proctoring service. After wasting about 20 minutes troubleshooting, I made the call to switch to a laptop with an integrated webcam.

That decision came with another hurdle: I had to fully import my Kali VM and restore my notes. Thankfully, I had backups prepared.

After reconnecting and completing the check-in process, I was finally able to start the exam around 7:35 PM.

A Rough Start (and a Valuable Lesson)

I was already flustered from the setup issues and rushed straight into the first challenge without taking a breath — a mistake.

A wise man once told me: “The perfect plan goes out the window once the bullets start flying.”

That quote had never felt more accurate.

I completely abandoned my methodology and began frantically scanning code, hoping something would jump out. Panic set in when the authentication bypass wasn’t immediately obvious like it had been in the Challenge Labs.

That’s when I forced myself to step away for a short break.

First takeaway: slow down.

Taking that tactical pause cleared my head and allowed me to reset back into a structured mindset.

Regaining Control and Finding the First Chain

Once I returned with a clear head, I quickly identified the first vulnerability in the authentication bypass chain — and that word is important: chain.

Just like the labs, the bypass wasn’t a single flaw. It required multiple steps working together.

As I continued reviewing the code and enumerating application functionality, I uncovered a key piece of the puzzle that wasn’t immediately obvious. With all components identified, I spent the next three and a half hours developing and automating my proof-of-concept exploit.

Eventually, I captured my first flag.

During that same code review process, I had already spotted the RCE path, which allowed me to obtain the second flag fairly quickly afterward.

I wrapped up my exploit script, reverted the target system, and tested everything again — only to discover my entire script was broken.

After several frustrating hours of troubleshooting, I realized I had missed a single variable in my execution command. Once corrected, everything worked exactly as expected.

At that point, it was late, and I decided it was best to get some rest.

Day Two — Momentum Builds

After a few hours of sleep (and a healthy amount of coffee), I woke up feeling refreshed and immediately documented everything from the first challenge in my report.

Quick side note — a non-sponsored shoutout to Sysreptor. I used their community edition reporting platform along with OffSec’s official report templates, and it made the reporting process significantly smoother.

You can find it here: https://github.com/syslifters/sysreptor/

With documentation complete, I moved on to the second challenge.

This time, I stuck strictly to my methodology — and it paid off.

I identified the vulnerabilities fairly quickly. However, exploit development took longer than expected because I had overlooked some subtle input sanitization happening in the code. I spent several hours troubleshooting payloads before realizing what I had missed.

Once that clicked, everything fell into place.

About two hours later, I successfully bypassed authentication and captured my third flag.

At this point, I had enough points to technically pass, but with plenty of time remaining, I pushed forward for the final flag.

Before continuing, I fully documented everything again and tested all exploit scripts to ensure reliability.

The Final Challenge (and Another Lesson in Code Review)

This is where things became interesting.

I had already identified what I believed was the RCE vector — but I couldn’t trigger it.

Assuming it might be a rabbit hole, I went searching for alternative paths. After nearly an entire working day of frustration, I realized the truth:

It wasn’t a rabbit hole.

The problem was simple — I hadn’t read the code carefully enough.

Second takeaway: always read the code thoroughly.

It was late again, so I stepped away and got some rest.

The Final Push

On the morning of the last day, I returned refreshed and immediately spotted the RCE trigger I had previously overlooked.

I moved straight into payload development, testing everything I could think of — only to hit another wall.

Once again, I had missed a small but critical detail in the code.

After walking through the logic one more time, I finally crafted a working payload.

Moments later, I captured the final flag.

Wrapping Up and Submitting

With all objectives complete, I:

• Finalized my report
• Tested every exploit script again
• Did a brief victory dance

That’s when I learned one last lesson:

Take good notes.

I realized I had missed a few key screenshots needed for the report. Thankfully, I caught it before ending the lab environment. After grabbing what I needed, I officially ended the exam around 39 hours in.

I spent the next few hours polishing the report, double-checking technical accuracy, and ensuring everything was clearly documented.

Then — submission.

The Result

After what felt like an eternity of waiting, I received the email:

I officially passed and earned the OSWE certification.

Final Thoughts

Overall, this was hands down the best OffSec course and exam experience I’ve had.

The updated course material, Challenge Labs, and exam structure truly complement each other. Everything felt intentional, practical, and directly applicable to real-world web application testing.

OffSec absolutely nailed it with this revision of AWAE/OSWE.

Thanks for taking the time to read my experience and review. Until next time.
