ASP.NET Misconfiguration: Request Validation Disabled

C#/VB.NET/ASP.NET

Abstract

ASP.NET 検証フレームワークを使用して、未検証の入力によってもたらされる脆弱性を防止します。

Explanation

ASP.NET アプリケーションの脆弱性の主要な原因は、未検証の入力です。Cross-Site Scripting、Process Control や SQL Injection などのさまざまな脆弱性の原因は入力の未検証です。

そのような攻撃を防止するため、ASP.NET 検証フレームワークを使用してすべてのプログラム入力を確認してからアプリケーションに処理させます。

検証フレームワークの使用例には、次の点を確認する検証が含まれます。

- 電話番号フィールドには、電話番号で有効な文字だけが含まれる。
- ブール値は「T」と「F」のいずれかだけである。
- 自由入力の文字列は適切な長さと形式にする。
