ASP.NET Misconfiguration: Header Checking Disabled(header_checking_disabled)

ABSTRACT

禁用頭文件檢查會使攻擊者對頭文件操作發起攻擊，如 HTTP response splitting。

EXPLANATION

在默認情況下，.NET 框架會阻止將換行符發送到設置頭文件值的 API。但是，如果將 <httpRuntime> 標簽上的 enableHeaderChecking 屬性設置為 false，則可在配置文件中禁用此行為。
如果禁用該檢查，那么允許用戶輸入以訪問頭文件設置 API 的代碼將容易受到類似 HTTP response splitting 的攻擊。
