Lab: Server-side template injection in a sandboxed environment


This lab uses the Freemarker template engine. It is vulnerable to server-side template injection due to its poorly implemented sandbox. To solve the lab, break out of the sandbox to read the file my_password.txt from Carlos's home directory. Then submit the contents of the file.
