Project: Drupal core [1]
Date: 2018-April-25
Security risk: *Critical* 17∕25
AC:Basic/A:User/CI:All/II:All/E:Theoretical/TD:Default [2]
Vulnerability: Remote Code Execution

Description: 
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
compromised. This vulnerability is related to Drupal core - Highly critical -
Remote Code Execution - SA-CORE-2018-002 [3]. While SA-CORE-2018-002 is being
exploited in the wild, this vulnerability is not known to be in active
exploitation as of this release.

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

  * If you are running 7.x, upgrade to Drupal 7.59 [4].
  * If you are running 8.5.x, upgrade to Drupal 8.5.3 [5].
  * If you are running 8.4.x, upgrade to Drupal 8.4.8 [6]. (Drupal 8.4.x is 
no
    longer supported and we don't normally provide security releases for
    unsupported minor releases [7]. However, we are providing this 8.4.x
    release so that sites can update as quickly as possible. You should 
update
    to 8.4.8 immediately, then update to 8.5.3 or the latest secure release 
as
    soon as possible.)

If you are unable to update immediately, or if you are running a Drupal
distribution that does not yet include this security release, you can attempt
to apply the patch below to fix the vulnerability until you are able to
update completely:

  * Patch for Drupal 8.x [8] (8.5.x and below)
  * Patch for Drupal 7.x [9]

These patches will only work if your site already has the fix from
SA-CORE-2018-002 [10] applied. (If your site does not have that fix, it may
already be compromised [11].)
