Content This app is part of the MCH2022 CTF. Please see ctf.mch2022.org for more details. Find the vulnerability and exploit your own badge. You can obtain a flag by running your exploit against badges that have red LED's (hint: the challenge author maybe?). The color of the LED's indicate the challenge status: * BLUE: you need to update the app to the latest version before you continue * GREEN: everything is set! Find the vuln and write your exploit. However your badge does not contain a real flag * RED: once you have finished your exploit, find someone with red LED's and run your exploit against their badge.
