View online: https://www.drupal.org/sa-core-2020-005

Project: Drupal core [1]
Date: 2020-June-17
Security risk: *Critical* 17∕25
AC:Complex/A:None/CI:All/II:All/E:Theoretical/TD:Uncommon [2]
Vulnerability: Arbitrary PHP code execution

CVE IDs: CVE-2020-13664
Description: 
Drupal 8 and 9 have a remote code execution vulnerability under certain
circumstances.

An attacker could trick an administrator into visiting a malicious site that
could result in creating a carefully named directory on the file system. With
this directory in place, an attacker could attempt to brute force a remote
code execution vulnerability.

Windows servers are most likely to be affected.

Solution: 
Install the latest version:

  * If you are using Drupal 8.8.x, upgrade to Drupal 8.8.8 [3].
  * If you are using Drupal 8.9.x, upgrade to Drupal 8.9.1 [4].
  * If you are using Drupal 9.0.x, upgrade to Drupal 9.0.1 [5].

Versions of Drupal 8 prior to 8.8.x are end-of-life and do not receive
security coverage. Sites on 8.7.x or earlier should update to 8.8.8.
