Injection Vulnerabilities

Injection Vulnerabilities

Learn injection vulnerabilities, one of the most damaging categories of web security flaws. When user input is treated as executable commands or trusted database logic, attackers can move from simple requests to system compromise and large-scale data theft. This course teaches you how command injection and SQL injection work, how to exploit them manually, and how to use automation when the workflow becomes too large for hand testing alone.

Why It Matters

Injection flaws remain important because they expose the boundary between user input and trusted execution. A small validation mistake can let an attacker run operating system commands, bypass authentication, read sensitive tables, or take control of an application workflow.

This course emphasizes method, not just tooling. You will learn how to recognize likely injection points, reason about backend behavior, extract data step by step, and decide when automation adds value instead of replacing understanding.

What You Will Learn

• Identify and exploit command injection in vulnerable web functionality.
• Use boolean-based and union-based SQL injection to manipulate database queries.
• Extract database structure and sensitive records through manual SQLi workflows.
• Use sqlmap to automate discovery and large-scale database extraction responsibly.
• Chain multiple injection techniques in a realistic database compromise scenario.

Course Roadmap

• Command Injection Detection: Exploit unsafe input handling to execute operating system commands.
• Manual SQL Injection (SQLi) Basics: Learn the logic behind SQLi by manually bypassing application checks.
• Union-Based SQL Injection: Extract schema details and data by building more advanced SQLi payloads.
• Automated SQLi with SQLmap: Use sqlmap to expand manual findings into faster database enumeration and dumping.
• Database Compromise Mission: Apply both manual and automated techniques to break into a vulnerable application and exfiltrate sensitive data.

Who This Course Is For

• Learners entering hands-on web exploitation.
• Security testers who want a stronger foundation in manual SQLi reasoning.
• Defenders who need to understand how injection flaws become full compromise paths.

Outcomes

By the end of this course, you will be able to identify common injection patterns, exploit them methodically, and explain how weak input handling can escalate into database or system compromise.
