Detailed information about this program

Becoming OSWE certified - 48-hour proctored: All exams are proctored by an OffSec employee in a private VPN - Hands-on labs: Identify, exploit, and report real-world vulnerabilities in live lab systems - Compromise multiple machines: You’re required to write a professional report describing your exploitation process for each target - Retrieve proof files: Failure to provide the appropriate documentation or proof files for a specific exam objective may result in partial or zero points being awarded for that objective Train to become OSWE certified WEB-300: Advanced Web Attacks and Exploitation WEB-300 (Advanced Web Attacks and Exploitation) provides experienced offensive cybersecurity 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 skill used to analyze the target web applications and exploit development. 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 security and 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.

What You'll Learn

Key competencies developed through this program

Auto-populated·from NSX Competency Framework

Mastery: developing (Level 2)(based on Certification)

  • Multi-phase penetration testing methodologies — execute with reduced oversight across network, web application, and social engineering test vectors in client environments.
  • Exploitation frameworks such as Metasploit and custom scripts — deploy independently to validate discovered vulnerabilities and demonstrate proof-of-concept exploits.
  • Operating system and application server software — analyze configurations and misconfigurations to identify privilege escalation paths on enterprise infrastructure.
  • Complex problem-solving techniques — apply when encountering non-standard defenses or unexpected system behaviors during live penetration engagements.
  • Intermediate-level assessment reports — author with clear technical narratives, risk ratings, and remediation recommendations for both IT staff and business stakeholders.
  • Database management system software — test for authentication bypass, privilege abuse, and data exposure vulnerabilities in routine client database assessments.
  • Cloud-based management software and infrastructure — assess for misconfigured permissions, exposed storage buckets, and insecure API endpoints in cloud tenancy reviews.
  • Staff and end users reporting security incidents — assist in troubleshooting and correlating symptoms to identify whether issues stem from active compromise or system malfunction.
  • Object-oriented and scripting development environments — write and adapt exploit proof-of-concept code to validate specific vulnerability classes in target applications.
  • Inductive reasoning and pattern recognition — apply across multiple client engagements to identify recurring vulnerability trends and refine testing efficiency.
