This section will explain what vulnerabilities are common in python developments, how to exploit and fix them.
For the purpose of learning all this vulnerabilities I've create a vulnerable server that will allow practice and execution of the provided examples, but is better if try to break by yourself googling for information about the technologies or the bugs.
To run the service on port http://localhost:5000
docker run --name vuln_server \--rm -ti -p 80:5000 \egonzalez90/vuln_python_server:latest
Once in the main page, browse through the menu and try to get the flag at
/root/flag exploiting the different techniques.
Other command and files can also be executed, just be careful if mount other volumes in the container.

Happy hacking and fixing vulnerabilities ;)
