Race Condition漏洞

# Race Condition Playground 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.
