Offensive Security Web Expert (OSWE/OSCP) | Red Team Pentest

Master the WEB-300: Advanced Web Attacks and Exploitation certification with this comprehensive practice exam course! Designed to mirror the intensity of the OffSec Web Expert (OSWE) exam, this course goes beyond theory, focusing on practical application and reinforcing your ability to manually discover, triage, and exploit complex web application vulnerabilities using offensive security techniques.

This course features six in-depth practice tests, each aligned with core OSWE topics and real-world web attack chains. You'll not only learn to identify individual vulnerabilities but also how to chain multiple flaws across different layers of an application. Develop report-ready findings and understand the secure coding implications behind each exploit.

Here's a breakdown of the key domains covered:

• Domain 1: Reconnaissance & Source Code Analysis

  • Topics: Web Security Tools, Methodologies, Source Code Analysis
  • Master the foundational skills for both black-box and white-box vulnerability discovery. Analyze PHP, JavaScript, and .NET code to uncover logic flaws, insecure authentication, file upload bypasses, and more, utilizing tools like Burp Suite and browser developer consoles.

• Domain 2: Injection Attacks – SQLi & Code Execution

  • Topics: Blind SQL Injection, Remote Code Execution
  • Explore advanced manual SQL injection techniques, including time-based and content-based blind attacks. Learn to chain these attacks into full command execution by understanding how ORM misconfigurations, input filtering, and weak error handling can lead to complete compromise.

• Domain 3: Deserialization & .NET-Specific Attacks

  • Topics: .NET Deserialization, Remote Code Execution (via deserialization)
  • Learn to exploit insecure object serialization in .NET environments. Practice crafting ViewState exploits, leveraging BinaryFormatter abuse, and building custom gadget chains to achieve remote code execution in enterprise applications.

• Domain 4: SSRF, Data Exfiltration & Internal Access

  • Topics: Advanced Server-Side Request Forgery (SSRF), Data Exfiltration
  • Simulate complex SSRF scenarios leading to metadata exposure, cloud credential theft, and internal pivoting. Understand how attackers escalate SSRF to file write, internal API abuse, and ultimately, remote access or exfiltration of sensitive data.

• Domain 5: Client-Side Exploitation & Session Abuse

  • Topics: Persistent Cross-Site Scripting (XSS), Session Hijacking
  • Develop the ability to exploit persistent XSS vulnerabilities in modern applications and use them to hijack user sessions, bypass Content Security Policy (CSP) protections, and perform privilege escalation. Examine real-world XSS chains that lead to full admin takeover.

• Domain 6: Modern JavaScript Attacks – Prototype Pollution

  • Topics: JavaScript Prototype Pollution (Optional chaining with XSS or SSRF)
  • Dive into prototype pollution, a powerful but often overlooked front-end attack class. Learn how to exploit it to escalate privileges, bypass client-side logic, or chain it with other vulnerabilities like XSS or SSRF.

By the end of this course, you'll have significantly improved your ability to identify and exploit complex web application vulnerabilities, strengthen your readiness for the OSWE exam, and gain practical experience with the core techniques needed for real-world offensive web security engagements.
