### 简要描述：
demo也shell了哦
### 详细说明：
看到\member\api\uc.php
```
define('DISCUZ_ROOT', dirname(dirname(dirname(__FILE__))).'/member/ucenter/');
include DISCUZ_ROOT.'api/uc.php';
```
就是包含了uc的那个插件。但是这个功能只有高级版才有，免费版没有
然后uckey都是默认的
```

```
然后就可以直接getshell了
附上脚本
```

```
### 漏洞证明：
先来个demo的shell
```
http://**.**.**.**/member/ucenter/config.inc.php
```

然后再来几个案例
```
http://**.**.**.**//member/ucenter/config.inc.php
```
```
http://**.**.**.**/member/ucenter/config.inc.php
```
```
http://**.**.**.**/member/ucenter/config.inc.php
```
```
http://**.**.**.**/member/ucenter/config.inc.php
```
```
http://**.**.**.**/member/ucenter/config.inc.php
```
密码都是1
