WannaRace – WebApp Intentionally Made Vulnerable To Race Condition For Practicing Race Condition


WebApp intentionally made vulnerable to Race Condition


Description

Race Condition vulnerability can be practiced in the developed WebApp. Task is to buy a Mega Box using race condition that costs more than available vouchers. Two challenges are made for practice. Challenge B is to be solved when PHPSESSID cookie is present, cookie is auto created when user is logged in. Happy learning


Building and running the docker image

Build the docker image with:

git clone https://github.com/Xib3rR4dAr/WannaRace && cd WannaRace
docker build -t xib3rr4dar/wanna_race:1.0 .
