In this episode, we are taking SSTI from something people copy payloads for to something you actually understand. Server Side Template Injection is one of the most dangerous web vulnerabilities, but most hunters only memorize syntax instead of learning how the engines work.
In this video, I break down SSTI from first principles. Jinja2, Twig, FreeMarker, Razor. Detection, fingerprinting, RCE, blind techniques, out of band payloads, polyglots, and the logic behind every step.
