[topthink/framework] ThinkPHP Framework vulnerable to remote code execution

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.
