Updates released on Wednesday for Drupal 7 and 8 patch several vulnerabilities affecting third-party Symfony and jQuery components used by the Drupal core.
The developers of the Symfony PHP web application framework on Wednesday released updates that patch five vulnerabilities, including three that also impact the Drupal content management system (CMS).
The Symfony flaws can allow an attacker to execute arbitrary code (CVE-2019-10910), authenticate as a different user by modifying a cookie (CVE-2019-10911), and launch cross-site scripting (XSS) attacks (CVE-2019-10909).
The latest versions of Drupal also address a jQuery vulnerability patched earlier this month with the release of jQuery 3.4.0. The security hole, related to the jQuery.extend() function, can allow XSS attacks.
“It’s possible that this vulnerability is exploitable with some Drupal modules. As a precaution, this Drupal security release backports the fix to jQuery.extend(), without making any other changes to the jQuery version that is included in Drupal core (3.2.1 for Drupal 8 and 1.4.4 for Drupal 7) or running on the site via some other module such as jQuery Update,” Drupal developers said.
Drupal patched these vulnerabilities with the release of versions 8.6.15, 8.5.15 and 7.66.
While these flaws have been described as “moderately critical” and are less likely to be exploited in the wild, Drupal users should do their best to keep their installations up-to-date considering that it’s not uncommon for malicious actors to start exploiting vulnerabilities shortly after they have been fixed.
In late February, researchers noticed that a Drupal vulnerability patched just three days earlier had been exploited in the wild to deliver cryptocurrency miners and other types of payloads.
