System Information Leak: PHP Errors

Abstract

データやデバッグ情報の開示は、システムについて攻撃者に教えることになり、攻撃の計画が立てやすくなります。

Explanation

display_errors オプションが有効に設定されている場合、エラーが Web ブラウザに表示されるので、潜在的な脆弱性が攻撃者に明らかになる可能性があります。たとえば、あるデータベースのエラーメッセージから、アプリケーションが SQL Injection 攻撃に対して脆弱であることがわかる場合があります。また、他のエラーメッセージがシステムに関する間接的な手がかりを示すことがあります。
