PHP Misconfiguration: allow_url_include Enabled

Abstract

원격 파일을 참조하는 include 문을 사용하면 공격자가 악성 콘텐트를 프로그램에 삽입할 수 있습니다.

Explanation

allow_url_include 옵션이 활성화되면 원격 파일에서 HTTP 또는 FTP URL을 수락할 수 있도록 하는 include() 및 require()와 같이 현재 페이지에 포함시킬 파일을 지정하는 PHP 함수를 허용합니다. PHP 5.2.0에서 도입되 기본적으로 비활성화되어 있는 이 옵션은 공격자가 응용 프로그램에 악성 콘텐트를 전송할 수 있기 때문에 위험합니다. 최고의 보안 상태에서 원격 파일 작업을 포함하여도 원격 파일을 수정하여 악성 콘텐트를 포함시키는 공격자에게 응용 프로그램이 취약해집니다. 공격자가 응용 프로그램에서 포함할 원격 파일을 지정하는 데 사용하는 URL을 제어할 수 있는 경우, 공격자는 URL을 원격 서버에 제공하여 임의의 악성 콘텐트를 응용 프로그램에 삽입할 수 있습니다.
