Security Fix for Joomla

Source: Security hotfixes for Joomla EOL versions – Joomla! Documentation

joomla34graphicThe Joomla project has just released Joomla 3.4.6 to address a Critical Vulnerability.

The vulnerability is also present in discontinued Joomla 2.5 and 1.5 series (Joomla 1.0 is ok). If you still have sites running off these old Joomla versions you must patch them appropriately.

For these old versions, a simply file replacement is all that is needed.

2020Media will happily undertake this replacement for any Joomla user, whether they are a customer or not. Please let us know if we can help by contacting us.

PHP File Directory Script with folder sizes

A new resource for customers – the Website File Explorer. Here’s how it came about.

What it does

The item lists the files and folders in a customers webspace, giving information such as file size, modification time, folder structure and size, all in a responsive, attractive layout.

Based on the script created by Hal Gatewood at http://halgatewood.com/free/file-directory-list/ we made a modification to show the folder sizes and give a total for the space used entirely.

The single-file script can be placed in a web directory and loaded in a browser. It uses scandir to locate all the contents recursively, then filesize to get the properties of each item.

Responsive, Dynamic, Modern

The script also displays a nice icon for each type of file, and the last modified timestamp.

Folders are shown initially closed but a simple click expands them dynamically to reveal the contents.

Putting the Customer in Control

The script is used as a report for our web hosting customers, to give them more information about their accounts.

Most hosting control panels show disk quota and usage, but we were asked by customers to break down the usage in detail, so that they could get an idea where the space was being used. From personal experience we know webspace gets used over time for all sorts of random things – obsolete projects, testing space, a handy spot to dump that file you need to transfer one time only….

We had been providing this information manually, using the linux du‘ command. This has useful parameters such as –human-readable and –max-depth which made it ideal. However translating this function into a customer-facing tool in a safe and secure way meant a different approach – in our case using PHP.

We continue to use ‘du’ “under the hood” to provide a daily report to customers via our customer portal. Automatic warnings are generated in case a customers is getting close to their quota.

How big is that Folder in the Window?

One interesting thing we found is the different ways that file and folder sizes are calculated. There is also some differences in parameters for du (apparent sizes, rather than disk usage) that had to be taken into account when comparing PHP’s method of calculating file space usage with Linux’s (and our FTP server software).

We display the results in human-friendly units based on one Kilobyte being 1024 bytes.

Download Script

Download the script here: file-directory-size.php.txt

Remove the .txt extension and upload to your webserver.

Caution: This script will display the names (at least) of all files in your site. Therefore caution should be used before putting it in a public location. Our use of this script is tightly locked down so that it is safe and secure to use.

We would not recommend this script is used at all where register_globals is active (e.g. older php versions).
