Cookie Security: HTTPOnly not Set on Application Cookie

C#/VB.NET/ASP.NET

Abstract

程序未将 HttpCookie.HttpOnly 属性设置为 true。

Explanation

httpOnlyCookies 属性的默认值为 false，这意味着可通过客户端脚本访问 Cookie。这是一个不必要的 Cross-Site Scripting 威胁，会导致 Cookie 被盗。被盗的 Cookie 可能包含用于识别站点用户的敏感信息，例如 ASP.NET 会话 ID 或表单验证票据，攻击者可以重新放置这些信息以伪装成用户或获取敏感信息。
示例 1：易受攻击的配置：


<configuration>
  <system.web>
    <httpCookies httpOnlyCookies="false">
