This guide details the comprehensive methodology for detecting and exploiting Server-Side Template Injection (SSTI) vulnerabilities across multiple popular template engines, including Jinja2, Twig, and Freemarker. It provides step-by-step workflows, covering payload detection using basic arithmetic expressions, engine identification, and executing advanced Remote Code Execution (RCE) payloads for penetration testing purposes.

This skill provides a comprehensive checklist and methodology for identifying Server-Side Template Injection (SSTI) vulnerabilities. It covers template engine identification (e.g., Jinja2, Twig), polyglot payload generation, systematic detection methods, and executing engine-specific Remote Code Execution (RCE) payloads. Ideal for security professionals testing web application input sanitization.

This expert playbook provides comprehensive techniques for exploiting Server-Side Template Injection (SSTI). It covers polyglot detection probes, engine fingerprinting (Jinja2, Twig, FreeMarker, etc.), sandbox escape mechanisms (MRO chains), and advanced bypass techniques. Essential reading for security researchers and penetration testers assessing application vulnerabilities.
