Highly CRITICAL Drupal Vulnerability! (PSA-2018-001) (Affects Drupal 6,7,8)

Recently the Drupal Security Team released the first PSA of 2018 letting the world know that there is an upcoming critical release for Drupal Core that will be released on March 28th 2018 between 18:00 – 19:30 UTC.

Now the implications of this PSA may be subtle to some, but it’s subtlety shows how severe the issue is that they are patching.

You see, generally projects don’t release beforehand that they are working on a patch for an un-released vulnerability, but instead announce that there is a vulnerability that was fixed when the release a patch. So, what the Drupal Security Team is doing here, is letting you know that this is so important, they want everyone to be ready to apply this patch just as soon as it releases. They are doing this as they expect that practical exploits could “developed within hours” of release of the patch.

On top of this, Drupal is choosing to patch more than just the two current “stable” core releases (7.x and 8.5.x) but instead ALSO patching the “unsupported minor releases” 8.3.x, and 8.4.x. Again, the fact that they are choosing to patch more than the main branch of code shows exactly how horribly this exploit could be for users of the Drupal CMS.

The full text of PSA-2018-001 can be seen quoted below, but may also be read at this url: https://www.drupal.org/psa-2018-001

The Drupal Security Team has promised that the announcement for the patch will be made public via:

Update:  Exploit Affects Drupal 6 Also!

As can be seen by viewing recent commits to the Drupal 6 LTS code repository, the current exploit also affects the fully un-supported Drupal 6 branch.

While the Drupal 6 LTS team is working on patches for the latest Drupal 6 Release, these patches will need to be implemented by someone considerably savvy with code repositories, and patching code. As such they recommend you use a provider that has experience patching software or are part of the official Drupal 6 LTS Vendor list. It is worth noting, that Drupal 6 is no longer officially supported as of Feb 24th, 2016.
