Critical PHPMailer & SwiftMailer Security Updates

Although the PHPMailer vulnerability was posted to our Script Security Forum a couple days ago, the widespread and critical nature of these warrants a post here as well. PHPMailer and SwiftMailer are both libraries used for sending emails. A very large number of scripts use one of these two libraries, including WordPress, Drupal, SugarCRM, Joomla and many others. Both libraries contain similar remote code execution vulnerabilities that can be exploited under certain circumstances.

It is very important that you make sure all instances of these libraries are updated. This will, unfortunately, be difficult to pinpoint in some cases since many plugins also include these libraries. Every core script, plugin and theme that you use should be investigated to determine whether or not these libraries are included and require updating.

All instances of PHPMailer must be updated to 5.2.21 or higher, which can be downloaded here.

All instances of SwiftMailer must be updated to 5.4.5 or higher, which can be downloaded here.

This would also be a good time to examine your plugins and themes to make sure they are all being actively maintained. As a general rule, if they haven’t received any updates within 6 months you should be concerned. If they haven’t received any updates within the past year, they probably shouldn’t be used at all.

The ongoing use of abandoned projects are one of the bigger risks that face websites like those powered by WordPress. While such a plugin may appear to be all good and up-to-date from within the WordPress admin panel, the developers may not have touched it in years and the project page may no longer even exist. As such, a regular audit of these is a very good idea and in general you should stick to more popular options when possible.

If you run into any issues with updating or have any questions please feel free to post a comment here, post on our forums or submit a ticket via our portal.

Feature Spotlight – PHP Selector

As we get close to completing all of our server upgrades, I wanted to go ahead and quickly highlight a feature that is available on the new servers. We’ve permitted clients to change the version of PHP that their site uses for many years now but this has always required a modification to the domain’s .htaccess file. Although this wasn’t particularly difficult, it has been simplified even further with the inclusion of PHP Selector. PHP Selector is a CloudLinux component that sits on top of CageFS and allows each cPanel user to select their desired PHP version.

Once you’ve logged into cPanel you’ll find the “Select PHP Version” option under the “Software” menu group as shown below.

Critical Joomla Security Update

On Monday, December 14th, Joomla 3.4.6 was released to address a critical remote code execution vulnerability (CVE-2015-8562) that exists in all prior versions from 1.5.0 through 3.4.5. Hotfixes are also available for the older, unsupported 1.5 and 2.5 branches. It is imperative that you update all Joomla instances immediately. This was a zero day vulnerability that was actively being exploited prior to it having been discovered and patched. As such, it is remotely possible that your Joomla was already compromised.

We posted this to our forums and in our portal on Monday to give our clients a heads up but given the critical nature of this we figured another post couldn’t hurt. At that time we also deployed mod_security rules which we believe to sufficiently protect all Joomla instances hosted by us unless you have specifically disabled mod_security on the domain, which is not the default or recommended. As always, though, it is still important that these latest patches be applied immediately in order to secure your Joomla instances.

If you have any questions or concerns please don’t hesitate to contact us and we hope everyone has a Merry Christmas!
