Often Misused:Spring Remote Service 经常被误用：Spring远程服务

 

Abstract:

 

在 remoting-servlet.xml 文件的第 11 行，应用程序会以远程服务的形式暴露 spring bean。默认情况下，这些远程服务不要求身份验证，也不要求进出该服务器的信息必须是明文形式。这就使攻击者有机会访问需要特定权限的操作或者获取敏感数据。

 

 

Explanation:

 

Spring 提供了一种简单的机制，可用于将任何 Spring 托管的 bean 转换为可通过 RMI、HTTP、Burlap、Hessian 和 JMX 等协议暴露给外部的对象。远程 Spring bean 的任何公共方法都支持外部调用，而且客户端与远程对象之间传递的数据都是明文形式。这些服务存在的主要问题是，它们在默认情况下是开放的，而且本身不提供任何保密性或完整性保证。

Recommendations:

 

利用 Spring Security 和 SSL 提供 authentication、授权、保密性和完整性。

 

 

Tips:

 

1. 确保使用 Spring Security 或某种其他机制为远程服务提供 authentication、授权、保密性和完整性。
