Drupal: If you weren't quick to patch, assume your site was hacked

Drupal site owners who failed to rapidly deploy a recent critical patch were advised to restore their sites from backups

Users of Drupal, one of the most popular content management systems, should consider their sites compromised if they didn't immediately apply a security patch released on Oct. 15.

The unusually alarming statement was part of a "public service announcement" issued by the Drupal project's security team Wednesday.

"Automated attacks began compromising Drupal 7 websites that were not patched or updated to Drupal 7.32 within hours of the announcement of SA-CORE-2014-005 - Drupal core - SQL injection," the Drupal security team said. "You should proceed under the assumption that every Drupal 7 website was compromised unless updated or patched before Oct 15th, 11pm UTC, that is 7 hours after the announcement."

The SA-CORE-2014-005 advisory, published Oct. 15, warned used about a highly critical SQL injection vulnerability that affects Drupal versions older than 7.32. Exploiting the vulnerability does not require authentication and can lead to a complete website compromise.

The reason why Drupal's security team came out with a stronger warning and additional guidance Wednesday was because of the speed with which attackers began targeting this vulnerability and because a potential compromise can be very hard to detect.

"Attackers may have copied all data out of your site and could use it maliciously," the Drupal security team said. "There may be no trace of the attack."

The vulnerability also allows the installation of multiple backdoors in the site's database, code, file directories and other locations and it's impossible for an administrator to say with complete confidence that all of them were found. Attackers may use such backdoors to attack and compromise other services on the underlying Web server, allowing them to expand their access beyond the website itself, the Drupal security team said.

Users should try to determine whether their websites were patched by their hosting providers before the attacks began or if those providers successfully blocked all attack attempts. If that cannot be guaranteed, the best course of action, according to the Drupal team, is to take the sites offline, delete all their files and databases, restore them from backups made before Oct. 15 and then patch the sites before bringing them back online.

Users should also notify their server administrators that attackers might have compromised other sites and applications hosted on the same servers. If possible, the server should be changed completely before restoring a site. If restoring from a backup is not possible, rebuilding the site from scratch is a better alternative than attempting to clean it up, because backdoors can be extremely difficult to find, the Drupal security team said.

What can make this incident worse is that Drupal, unlike other content management systems like Joomla and WordPress, is heavily used by large organizations, said Daniel Cid, the chief technology officer of Web security firm Sucuri, in a blog post.

Unlike consumers and small businesses, large organizations have certain processes they have to follow when deploying patches and those can take time, he said.

"This is a recipe for disaster, if it's true and those websites are in fact compromised, they could be leveraged and daisy chained for a massive malware distribution campaign," Cid said. "Take that into consideration with the size and audience of brands and the impact grows exponentially."

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.
