Project: Drupal core [1]
Date: 2018-March-28
Security risk: *Highly critical* 21∕25
AC:None/A:None/CI:All/II:All/E:Theoretical/TD:Default [2]
Vulnerability: Remote Code Execution

Description:
CVE: CVE-2018-7600

A remote code execution vulnerability exists within multiple subsystems of
Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple
attack vectors on a Drupal site, which could result in the site being
completely compromised.

The security team has written an FAQ [3] about this issue.

Solution:
Upgrade to the most recent version of Drupal 7 or 8 core.

* *If you are running 7.x, upgrade to Drupal 7.58 [4].* (If you are unable
to update immediately, you can attempt to apply this patch [5] to fix the
vulnerability until such time as you are able to completely update.)
* *If you are running 8.5.x, upgrade to Drupal 8.5.1 [6].* (If you are
unable to update immediately, you can attempt to apply this patch [7] to
fix the vulnerability until such time as you are able to completely
update.)

Drupal 8.3.x and 8.4.x are no longer supported and we don’t normally provide
security releases for unsupported minor releases [8]. However, given the
potential severity of this issue, we /are/ providing 8.3.x and 8.4.x releases
that includes the fix for sites which have not yet had a chance to update to
8.5.0.

Your site’s update report page will recommend the 8.5.x release even if you
are on 8.3.x or 8.4.x. Please take the time to update to a supported version
after installing this security update.

* If you are running 8.3.x, upgrade to Drupal 8.3.9 [9] or apply this patch
[10].
* If you are running 8.4.x, upgrade to Drupal 8.4.6 [11] or apply this
patch
[12].

This issue also affects Drupal 8.2.x and earlier, which are no longer
supported. If you are running any of these versions of Drupal 8, update to a
more recent release and then follow the instructions above.

This issue also affects Drupal 6. Drupal 6 is End of Life. For more
information on Drupal 6 support please contact a D6LTS vendor [13].
