info:
  name: Thinkphp Lang - Local File Inclusion
  author: kagamigawa
  severity: critical
  description: |
    ThinkPHP Framework before 6.0.14 allows local file inclusion via the lang parameter when the language pack feature is enabled (lang_switch_on=true). An unauthenticated and remote attacker can exploit this to execute arbitrary operating system commands, as demonstrated by including pearcmd.php.
  remediation: |
    Apply the latest security patches and updates provided by the Thinkphp framework.
