How To Use The Jinja Template Engine In Python Flask Below is an example of a simple flask application with an ssti vulnerability. this application allows users to input their name, which is then rendered in a greeting message using jinja2 templating. This article, inspired by temple on tryhackme, demonstrates and dicusses server side template injection in flask and jinja2.
How To Use The Jinja Template Engine In Python Flask In python, ssti can occur when using templating engines such as jinja2, mako, or django templates, where user input is included in templates without proper sanitization. The focus was server side template injection (ssti) using flask and jinja2. instead of immediately making a vulnerable application, i deliberately built two versions:. However, one of the most dangerous and misunderstood vulnerabilities in modern web applications is server side template injection (ssti). in this article, i’ll walk through:. To give you a practical look into one of my favorite web vulnerabilities, i’ve built a purpose built lab focused on server side template injection (ssti). i've seen how this flaw can lead directly to remote code execution (rce), and i wanted to create a safe environment for you to see it too.

It introduces ssti, explains its significance, and guides the reader through understanding and exploiting ssti vulnerabilities using different template engines such as smarty for php, jinja2 for python, and jade for nodejs. Now we have established that ssti allows us to include and run server side code, lets see the kind of things we can do with it. we will deal with python flask jinja here. the approach should be similar in other python based stacks. ssti also exsits in php node.js and other frameworks. We are presented with a simple web application that allows users to “announce” a message. the text we input is rendered on the screen. the name of the challenge (“ssti1”) and the hint strongly suggest the vulnerability is server side template injection. We created and successfully executed a server side template injection in jinja and python. such injections are also possible in other programming languages and frameworks as well.
