By accessing it, a remote attacker can discover a large amount of information about the remote web server configuration to help conduct further attacks, including :

  • root/vps of the web server, operating system and PHP components
  • Details of the PHP configuration
  • Loaded PHP extensions with their configurations
  • Server environment variables.
