[PHP-DEV] Bug #13447 Updated: Security not blocking "unlink" delete functions From: ajo <email protected>
Date: 12/19/01

ID: 13447
User updated by: ajo <email protected>
Reported By: ajo <email protected>
Old Status: Feedback
Status: Open
Bug Type: Filesystem function related
Operating System: windows 2000
PHP Version: 4.0.6
New Comment:

I tried both adding a trailing slash (c:/pr/), and 4.1.0

You are still able to delete a file at your choosing. It's also interesting that the following has NO EFFECT.

php_admin_value disable_functions unlink

I have been unable to disable the command also.

I really want to get PHP setup, but I can't give global access to everyone.

Can you try adding a trailing slash (c:/pr/), and can you try 4.1.0???

Running PHP in Apache using the MODULE configuration.

Apache/1.3.14 (Win32) PHP/4.0.6 mod_ssl/2.7.2 OpenSSL/0.9.6 running.

With the following:

php_admin_flag safe_mode on
php_admin_value open_basedir c:/pr
php_admin_value doc_root c:/pr
php_admin_value user_dir c:/pr

IT SUCCESSFULLY blocks reads in directories other than c:/pr, but it DOES NOT block unlinks (file deletion) outside. So... My users cannot read other users files, however they can delete anything they want. Very strange. I DO NOT care about it checking "UIDs" as I do not create different Users for each USER... I want to be able to restrict access to a directory and call it good.

<?php

echo "Peace!";
//unlink ("c:/test.txt");// UNLINK WORKS (This should fail)
$fp = fopen ("c:/test.txt", "r"); // FAILS SECURITY CHECK
echo "Dude10";
?>
