Episode 84: Directory Traversal Vulnerabilities

When input isn’t properly restricted, users can end up accessing far more than intended. In this episode, we break down directory traversal vulnerabilities—flaws that allow attackers to manipulate file paths and access sensitive files or directories outside of the intended web root. You’ll learn how inputs like ../ or encoded path characters can lead to file exposure, configuration leaks, and credential disclosure.

We’ll also explore how these flaws are commonly found in poorly configured file upload or download functions, and how logging, file permissions, and input validation contribute to secure design. This episode prepares you to identify directory traversal issues in both scanner output and forensic investigation, giving you another high-priority vulnerability to recognize and report confidently.
