Episode 71 — Injection Families (SQL/Command/Template)

This episode teaches injection as a single core idea, untrusted input becomes an unintended instruction, then breaks that idea into the most common families you must distinguish in scenarios. You’ll learn how SQL injection manipulates database queries, how command injection triggers operating system execution, and how template injection abuses server-side rendering logic, with a focus on clue patterns like unexpected output, error behavior, and response timing rather than tool syntax. We’ll cover how impacts differ, from data disclosure and authorization bypass to system-level control, and why safe confirmation requires the smallest, least disruptive test that demonstrates control of interpretation. You’ll practice deciding which family fits a scenario based on symptoms, then selecting remediation concepts like parameterization, strict input handling, output encoding boundaries, and least privilege for service accounts. By the end, you’ll be able to classify injection scenarios accurately, avoid confusing encoding issues with true injection, and communicate findings in a way that supports practical fixes rather than generic warnings.
