Learn what Server-Side Template Injection (SSTI) is, why it can lead to remote code execution (RCE) in insecure apps, and the exact defensive steps developers must implement — no exploit code shown. Watch to protect your web apps today.
Server-Side Template Injection (SSTI) is one of the most dangerous web vulnerabilities when template engines are used insecurely. In this video we explain — in plain English — what SSTI is, how attackers can conceptually abuse template engines to escalate from data leakage to remote code execution (RCE), and most importantly how you can detect and prevent it in real applications. This is an educational video for developers, engineers, and security pros. No live exploit demonstrations against real systems are shown.
What you’ll learn:
• Clear definition of SSTI and how template engines evaluate user input.
• Conceptual paths from SSTI → information disclosure → command execution/RCE (explained safely).
• Signs of SSTI in logs, responses, and rendered output.
• Practical detection techniques for safe labs and CI testing (static analysis, fuzzing, unit tests).
• Strong mitigations: safe templating patterns, escaping strategies, input validation, least privilege, and runtime hardening.
• Recommended learning resources (OWASP, Web Security Academy, intentionally vulnerable labs).
Why watch: SSTI is low-noise but high-impact — fixing it reduces data leaks and prevents catastrophic RCE.
