PHP Misconfiguration: allow_url_include Enabled

Abstract

リモートファイルを参照する include ステートメントを使用すると、攻撃者が悪意あるコンテンツをプログラムに挿入できる可能性があります。

Explanation

allow_url_include オプションが有効に設定されていると、現在のページに追加するファイルを指定する PHP 関数 (include() や require() など) が、リモートファイルに HTTP または FTP URL を受け入れられるようになります。PHP 5.2.0 で導入されたこのオプションはデフォルトで無効に設定されており、攻撃者が悪意あるコンテンツをアプリケーションに持ち込める可能性があるという点で危険です。最も被害が小さい場合でも、リモートファイルを追加すると、アプリケーションはリモートファイルを改変して悪意あるコンテンツを追加する攻撃の危険にさらされます。最も被害が大きい場合、アプリケーションが追加するリモートファイルを指定するために使用する URL を攻撃者が制御できると、その攻撃者はリモートサーバーに URL を指定することで任意の悪意あるコンテンツをアプリケーションに挿入できます。
