This project is to demonstrate a vulnerable app that can be exploited by race condition attack.

Runs on Linux:

gunicorn -w 2 -k gevent -b 0.0.0.0:8000 race_condition_playground.wsgi

Runs on Windows:

waitress-serve --port=8000 race_condition_playground.wsgi:application

There is 4 routers that you can try to attack:

• /ucenter/1/
• /ucenter/2/
• /ucenter/3/
• /ucenter/4/

The first two contain race condition issues, the last two are secure.
