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.
- If you are using Drupal 8.9.x, upgrade to Drupal 8.9.1.
- If you are using Drupal 9.0.x, upgrade to Drupal 9.0.1.
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.
