J2EE Misconfiguration: Direct JSP Access

Java/JSP

Abstract

直接访问 Java Server Page 可能导致系统信息泄露、源代码泄露乃至任意代码执行。

Explanation

在使用 Web 框架（例如，Struts 或 Spring）构建的应用程序中直接访问 Java Server Page (JSP)，此类应用程序使用操作或 Servlet 将请求委托给 JSP，这样可能会引发未处理异常和系统信息泄漏。已使用经特殊技术处理的请求将实现或配置欠佳的应用程序服务器收编至泄露源代码详细信息，例如 http://host/page.jsp%00 或 http://host/page.js%2570。更糟糕的是，如果应用程序允许用户上传任意文件，攻击者可能会利用这项机制以 JSP 的形式上传恶意代码，并请求上传的页面在服务器上执行恶意代码。

示例 1：以下示例显示了构造欠佳的安全限制，明确允许直接访问角色名称中带有“*”的 JSP，这表示允许所有用户访问相应的 Web 资源。


<security-constraint>
    <web-resource-collection>
        <web-resource-name>JSP Access for Everyone!</web-resource-name>
        <description>Allow any user/role access to JSP</description>
        <url-pattern>*.jsp</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>*</role-name>
    </auth-constraint>
</security-constraint>
