Cct2019 Tryhackme May 2026

We can escalate the injection to read system files. A common payload:

 self.__class__.__mro__[2].__subclasses__() 

From the list of subclasses, search for file or subprocess.Popen. With careful chaining, we achieve remote code execution. cct2019 tryhackme

First Flag (user.txt): After gaining a basic shell (e.g., via a reverse shell payload injected into the template), we navigate to /home/chester or /home/user to find user.txt. We can escalate the injection to read system files

Content of user.txt: A 32-character hash (typical for TryHackMe rooms). From the list of subclasses, search for file
