PHP Bug Type: Zend Engine 2 problem
Bug description: Includes are not binary safe
Description:
------------
hello,
includes (include, require, etc.) are not binary safe.
It is very dangerous for beginners, who often use includes with
parameters.
In the following example, i kwow that you can test the file name with
pathinfo() but the current PHP behaviour is incorrect.
Reproduce code:
---------------
<?php
$file = $_GET['file'];
$path = $_SERVER['DOCUMENT_ROOT']."/includes/".$file.".class.php";
if(is_file($path)) {
include $path;
}
?>
Expected result:
----------------
index.php?file=Forum
Should work.
I suppose that the directory backups/Database.xml is protected by a
.htaccess and is not accessible with your browser.
index.php?file=../backups/Dabatase.xml%00
Should not work.
Actual result:
--------------
index.php?file=Forum
Should work.
index.php?file=../backups/Dabatase.xml%00
Works !
