<h1>项目介绍</h1>
<p>这是一款基于SpringBoot+SpringSecurity的RBAC权限管理系统。原本只想着做成基于SpringSecurity的权限管理系统，但随着功能的增加感觉有些刹不住车了，之后可能会往后台管理系统方向发展。无任何重度依赖，非常适合新手练习上手,项目文档从零开始，十分详细。</p>
<h1>项目搭建</h1>
<p>项目地址：<a href=https://gitee.com/witmy/my-springsecurity-plus target=_blank>https://gitee.com/witmy/my-springsecurity-plus</a></p>
<p>这个地址项目的是目前最新版，文章中审计的是先前的版本，部分漏洞最新版也存在，这个在文章中会说明，我会把老版本的漏洞产生代码段与新版本做对比，方便更直观理解漏洞的产生</p>
<p>打开项目等待maven加载</p>
<p><a id=img0 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202426-a316c714-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202426-a316c714-614a-1.png></a></p>
<p>修改配置文件，创建对应数据库</p>
<p>my-springsecurity-plus\src\main\resources\application.yml</p>
<p><a id=img1 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202434-a7b681ec-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202434-a7b681ec-614a-1.png></a></p>
<p>导入sql文件</p>
<p>sql文件：my-springsecurity-plus\docs\sql\my-springsecurity-plus.sql</p>
<p><a id=img2 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202445-ae8748d0-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202445-ae8748d0-614a-1.png></a></p>
<p>导入完成后，配置spring boot，jdk版本1.8</p>
<p>配置完成后启动项目即可</p>

<h1>漏洞挖掘</h1>
<h2 id=toc-0>SQL注入</h2>
<p>检查pom.xml文件，发现导入了mybatis依赖</p>
<p><a id=img5 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202535-cc62170e-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202535-cc62170e-614a-1.png></a></p>
<p>初步判断使用，全局搜索关键词<code>${</code></p>
<p><a id=img6 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202542-d03bf82c-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202542-d03bf82c-614a-1.png></a></p>
<h3 id=toc-1>第一处</h3>
<p>my-springsecurity-plus\src\main\resources\mybatis-mappers\DictMapper.xml</p>
<p><a id=img7 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202547-d3b0d482-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202547-d3b0d482-614a-1.png></a></p>
<p>根据<strong>id</strong>搜索Dao层对应方法</p>
<p><a id=img8 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202553-d6e702de-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202553-d6e702de-614a-1.png></a></p>
<p>往上查调用到controller层</p>
<p><a id=img9 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202558-d9be9c4c-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202558-d9be9c4c-614a-1.png></a></p>
<p>接着查调用</p>
<p><a id=img10 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202606-def1653c-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202606-def1653c-614a-1.png></a></p>
<p>查到controller文件，查看myDict是从哪来的，分析下这段代码</p>
<p><code>@RequestMapping</code>定义了基础路由 <code>/api/dict</code></p>
<p><code>@Api</code> 是Swagger文档生成标记控制器的</p>
<p><code>@Autowired</code>：注入 <code>DictService</code> 服务类，用于业务逻辑处理</p>
<p><code>index()</code>：处理 <code>GET /api/dict/index</code>请求，返回视图名 <code>system/dict/dict</code>。需要 <code>dict:list</code> 权限。</p>
<p><code>getDictAll()</code>：处理 <code>GET /api/dict</code> 请求，返回字典列表。需要 <code>dict:list</code> 权限，并记录操作日志 (<code>@MyLog("查询字典列表")</code>)。使用 <code>PageTableRequest</code> 和 <code>MyDict</code> 作为请求参数，调用 <code>dictService.getDictPage()</code> 返回分页数据。</p>
<p>什么？你说你看不懂代码？GPT啊！！！</p>
<p><a id=img11 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202620-e70a6020-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202620-e70a6020-614a-1.png></a></p>
<p>初期代码基础差，要学会使用工具，在这些信息中我们只提取我们需要的信息分析</p>
<p>首先这处功能点是在字典管理(代码中有注释，路由是触发/api/dict)</p>
<p>结合xml中的sql语句<code>%%</code>，应该是查询字典的功能</p>
<p>带入getDictPage方法执行的参数myDict会通过参数传递所以可控</p>
<p>分析完后，开始漏洞复现</p>
<p>在后台找到字典查询的功能点</p>
<p><a id=img12 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202628-ec0ef8e2-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202628-ec0ef8e2-614a-1.png></a></p>
<p>burp抓包</p>
<p><a id=img13 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202633-eefe7d70-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202633-eefe7d70-614a-1.png></a></p>
<p>参数名跟代码中对应上，保存数据包Sqlmap一把搜哈</p>
<p><a id=img14 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202640-f2d26646-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202640-f2d26646-614a-1.png></a></p>
<p>漏洞存在，新版本中这处注入修复了</p>
<p><a id=img15 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202644-f5789e24-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202644-f5789e24-614a-1.png></a></p>
<h3 id=toc-2>第二处</h3>
<p>my-springsecurity-plus\src\main\resources\mybatis-mappers\DeptMapper.xml</p>
<p><a id=img16 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202649-f82e9b96-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202649-f82e9b96-614a-1.png></a></p>
<p>一样的思路根据id关键字追到controller层调用</p>
<p><a id=img17 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202653-fac4bc64-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202653-fac4bc64-614a-1.png></a></p>
<p><a id=img18 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202656-fce303ca-614a-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202656-fce303ca-614a-1.png></a></p>
<p>跟到controller层调用</p>
<p>my-springsecurity-plus\src\main\java\com\codermy\myspringsecurityplus\admin\controller\DeptController.java</p>
<p><a id=img19 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202703-00c894b4-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202703-00c894b4-614b-1.png></a></p>
<p>这一处有点不一样，如果通过后台访问功能点数据包中是没有params这个参数的，这一块代码段也没发现params参数，那么它是哪来的呢？这一处卡了我很久</p>
<p>全局搜索params</p>
<p>定位到了这个类：my-springsecurity-plus-master\src\main\java\com\codermy\myspringsecurityplus\admin\entity\BaseEntity.java</p>
<p><a id=img20 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202710-04b274be-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202710-04b274be-614b-1.png></a></p>
<p>注释中也表明了是请求参数，params是Map类型的，如果为空就是new一个空的map，有值就会返回</p>
<p>通过类定位发现这是个抽象类，我们看下谁继承了它</p>
<p><a id=img21 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202717-08f562f2-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202717-08f562f2-614b-1.png></a></p>
<p>通过继承的类名也可以看出都是些数据库操作类,我们看下controller的导入</p>
<p><a id=img22 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202722-0bdb2d94-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202722-0bdb2d94-614b-1.png></a></p>
<p>发现是存在的，那么我们构造对应url</p>
<p><a href=http://192.168.37.1:8088/api/dept/build?params[ target=_blank>http://192.168.37.1:8088/api/dept/build?params["dataScope"]=1</a></p>
<p><a id=img23 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202728-0f621130-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202728-0f621130-614b-1.png></a></p>
<p>报错400，不应该啊？</p>
<p><a id=img24 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202745-19beab84-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202745-19beab84-614b-1.png></a></p>
<p>考虑到可能是字符的问题，url编码一下</p>
<p><a href="http://192.168.37.1:8088/api/dept/build?params%5B%22dataScope%22%5D=1" target=_blank>http://192.168.37.1:8088/api/dept/build?params%5B%22dataScope%22%5D=1</a></p>
<p><a id=img25 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202753-1e46d8f2-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202753-1e46d8f2-614b-1.png></a></p>
<p>发现可以解析了，上sqlmap</p>
<p><a id=img26 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202758-21550460-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202758-21550460-614b-1.png></a></p>
<p>新版本这处没改</p>
<h2 id=toc-3>XSS(存储型)</h2>
<p>由于这套系统只有后端管理，可以尝试的功能点不多，依旧是选择管理员能交互到的功能</p>
<p>我们先创建一个普通用户看下能操作哪些功能</p>
<p><a id=img27 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202815-2b626b64-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202815-2b626b64-614b-1.png></a></p>

<p>创建完成时已经弹窗了，基本确定了</p>
<p>模拟管理员查看用户</p>

<p>这个最新的也有，没对参数做校验</p>
<h2 id=toc-6>垂直越权</h2>
<p>查找用户操作的功能点，找到用户删除这个功能点，抓下包</p>
<p><a id=img32 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202852-41874fae-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202852-41874fae-614b-1.png></a></p>
<p>数据包中校验删除用户的条件貌似是userID,我们执行看下数据库执行记录</p>
<p><a id=img33 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202856-44452b26-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202856-44452b26-614b-1.png></a></p>
<p>看来是通过urse_id确认删除目标的，正常功能我们只能删除下级用户</p>
<p>那么我们可以尝试下删除同级用户</p>
<p><a id=img34 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202903-4865a53c-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202903-4865a53c-614b-1.png></a></p>
<p>成功删除test6</p>
<p><a id=img35 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202908-4b50ecde-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202908-4b50ecde-614b-1.png></a></p>
<p>最新版无法越权删除用户，貌似是加上JWT身份认证的原因，在做删除用户操作前会通过JWT校验用户权限</p>
<h2 id=toc-7>druid未授权(不存在)</h2>
<p>虽然不存在但是分析过程我感觉不错也写上</p>
<p>在pom.xml文件中看到了druid的依赖</p>
<p><a id=img36 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202916-5022492e-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202916-5022492e-614b-1.png></a></p>
<p>在后台发现确实存在对应功能</p>
<p><a id=img37 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202920-5246bcc6-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202920-5246bcc6-614b-1.png></a></p>
<p>在代码中查看对应配置，发现是允许访问Druid的监控界面</p>
<p><a id=img38 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202924-54964faa-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202924-54964faa-614b-1.png></a></p>
<p>我们在未登录的情况下尝试访问</p>
<p><a id=img39 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202929-57c6ef86-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202929-57c6ef86-614b-1.png></a></p>
<p>发现实际上是有做限制的，限制了访问ip，仅允许本地访问，我尝试了xff，绕过不了，说明不是从这里获取IP</p>
<p>我尝试在源码中寻找，发现是存在获取ip的代码段</p>
<p><a id=img40 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202936-5bc53688-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202936-5bc53688-614b-1.png></a></p>
<p>但是跟踪getIP这个方法的调用，没发现异常到这里就断了，这时我想到是不是把代码封装在jar里了，使用maven下载源代码</p>
<p>这次搜索报错信息</p>
<p><code>Sorry, you are not permitted to view this page.</code></p>
<p>定位到这个文件</p>
<p><a id=img41 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202942-5fb58252-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202942-5fb58252-614b-1.png></a></p>
<p>我一看路径，果然是jar包里面的，全局搜索文件名</p>
<p><a id=img42 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202947-6285e7ec-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202947-6285e7ec-614b-1.png></a></p>
<p>定位到验证代码段，代码中可以看出是关键是<code>isPermittedRequest</code>这个方法，我们跟进去看下</p>
<p><a id=img43 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202953-65cf45ec-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202953-65cf45ec-614b-1.png></a></p>
<p>看样子这个<code>getRemoteAddress</code>方法就是获取IP的了，继续跟进方法</p>
<p><a id=img44 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823202957-68700d5e-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823202957-68700d5e-614b-1.png></a></p>
<p>先判断remoteAddressHeader != null，查看remoteAddressHeader是个常量为null，那么直接看下面的if</p>
<p>通过request.getRemoteAddr()方法获取ip，确认了ip获取的方法</p>
<p>我尝试搜索了一下这个方法</p>
<p><a id=img45 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203004-6cbdeab6-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203004-6cbdeab6-614b-1.png></a></p>
<p>没想到第一篇就这么劲爆，看来这个方法是有绕过可能的</p>
<p>由于环境在本地，本地搭建dns服务器（过程就不放了），搭建完成后再次尝试</p>
<p><a id=img46 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203012-716ce526-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203012-716ce526-614b-1.png></a></p>
<p>寄，本地再起个测试环境看下获取到的ip</p>
<p><a id=img47 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203018-750c6b84-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203018-750c6b84-614b-1.png></a></p>
<p>客户端ip为：192.168.37.130</p>
<p>服务端ip为：192.168.37.1</p>
<p><a id=img48 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203023-77e3d702-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203023-77e3d702-614b-1.png></a></p>
<p>呜呜呜！欺骗我感情</p>
<p>自此判断不存在druid未授权</p>
<p>新版本取消了post方法的未授权访问，也就说可以未授权看到登入界面，但是登入不了，难崩</p>
<p><a id=img49 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203030-7c54ff32-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203030-7c54ff32-614b-1.png></a></p>

<h2 id=toc-8>Spring boot Actuator未授权访问</h2>
<p>这个其实是我之前一直没注意到的一个点，Spring boot框架已经成为java的主流之一，很多系统都采用Spring boot搭建，关于它上面的安全，确实应该重视，我自己也在思考总结思路，之后应该会专门出一篇见解下Spring boot的审计方向</p>
<p>这篇不会提太多</p>
<p>依旧是通过pom.xml发现引入了Actuator依赖</p>
<p><a id=img51 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203055-8ae125b2-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203055-8ae125b2-614b-1.png></a></p>
<p>稍微看过java审计文章的就会发现pom.xml对于java代审而言真的很重要，是可以等到很多信息的，要重点查看</p>
<p>在配置文件中寻找配置查看开放的端点</p>
<p>如果设置了<code>management.endpoints.web.exposure.include</code> 为 <code>*</code>，就可以在 <code>/actuator</code> 看到所有存在的端点</p>
<p><a id=img52 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203101-8ea55d80-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203101-8ea55d80-614b-1.png></a></p>
<p>但是它这里只开放了这几个</p>
<pre><code>/info
显示任意的应用信息
展示了关于应用的一般信息，这些信息从编译文件比如 META-INF/build-info.properties 或者 git 文件比如 git.properties 或者任何环境的 property 中获取
/health
显示应用的健康信息（当使用一个未认证连接访问时显示一个简单的’status’，使用认证连接访问则显示全部信息详情）
health一般只展示了简单的UP和DOWN状态
/beans
//显示一个应用中所有Spring Beans的完整列表
/env
//显示来自Spring的 ConfigurableEnvironment的属性
可能会泄露数据库账号密码等敏感信息
/metrics
//展示当前应用的metrics信息
获得每个度量的名称，其中主要监控了JVM内容使用、GC情况、类加载信息等</code></pre>
<p>比较重点的是/env，可能会泄露配置文件信息（并不是说其它没有）</p>
<p><a id=img53 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203111-94ce81fa-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203111-94ce81fa-614b-1.png></a></p>
<p><a id=img54 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203116-97d9168a-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203116-97d9168a-614b-1.png></a></p>
<p>针对env这种路径下泄露的密码会用<code>*</code>进行脱敏，想要获取对应的明文密码，可以尝试通过分析heapdump数据的方式</p>
<p>但是很可惜这套系统没有开放/heapdump端点</p>
<p>新版本也是直接不允许未授权访问/actuator了</p>
<p><a id=img55 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203126-9d4e5896-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203126-9d4e5896-614b-1.png></a></p>
<h2 id=toc-9>Swagger API泄露</h2>
<p>依旧是通过pom.xml发现依赖</p>
<p><a id=img56 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203131-a0b5903a-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203131-a0b5903a-614b-1.png></a></p>
<p>也设置了静态资源，也就是未授权了</p>
<p><a id=img57 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203135-a2cf5108-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203135-a2cf5108-614b-1.png></a></p>
<p>尝试访问</p>
<p><a href=http://127.0.0.1:8088/swagger-ui.html#/ target=_blank>http://127.0.0.1:8088/swagger-ui.html#/</a></p>

<p>提供了很多接口，但是能不能用，得测试</p>
<p>我们可以访问它提供的api地址</p>
<p><a href=http://127.0.0.1:8088/v2/api-docs target=_blank>http://127.0.0.1:8088/v2/api-docs</a></p>

<p>然后使用工具批量爬取接口测试存活</p>
<p><strong>swagger-hack</strong></p>
<p>项目地址：<a href=https://github.com/jayus0821/swagger-hack target=_blank>https://github.com/jayus0821/swagger-hack</a></p>

<p>测试结果会保存在csv文件中</p>
<p><a id=img61 href=https://xzfile.aliyuncs.com/media/upload/picture/20240823203158-b0d7a6e2-614b-1.png><img src=data:, data-sf-original-src=https://xzfile.aliyuncs.com/media/upload/picture/20240823203158-b0d7a6e2-614b-1.png></a></p>
<p>新版本和老版本这块没差别</p>
<h1>总结</h1>
<p>关于Spring boot框架常见的漏洞平时我确实没有注意，更多的都是通用漏洞和组件挖掘为主，对于框架易产生的漏洞较为疏忽，接触的也少，要让自己的思路扩展开来，多个攻击面出洞的几率就更高。这套源码实际上属于半成品，很多功能点都没开发，不知道后面作者会不会加，部分漏洞修补的也比较潦草。</p>
