ASP.NET Misconfiguration: Request Validation Disabled

ABSTRACT

使用 ASP.NET 驗證框架來防止由未經檢驗的輸入數據導致的漏洞。

EXPLANATION

在 ASP.NET 應用程序中，未經檢驗的輸入數據是漏洞產生的根源。未經檢驗的輸入數據會導致許多漏洞，如 cross-site scripting、process control 和 SQL injection。

為了避免此類攻擊，我們應在輸入數據被應用程序處理之前使用 ASP.NET 驗證框架來檢驗所有程序的輸入數據。

驗證框架的示例用法包括進行檢查以確保：

- 在電話號碼字段中只包含有效字符

- 布爾值僅為 "T" 或者 "F"

- 未限定格式的字符串必須具有合理的長度，并且由有效的字符組成
