Drupal core - SA-CORE-2019-003
CISA confirms exploitation of this vulnerability in real attacks. Prioritise checking whether your application is affected. CISA KEV · CC0 1.0
Some field types do not properly sanitize data from non-form sources. This can lead to arbitrary PHP code execution in some cases.
A site is only affected by this if one of the following conditions is met:
- The site has the Drupal 8 core RESTful Web Services (rest) module enabled and allows GET, PATCH or POST requests, or
- the site has another web services module enabled, like JSON:API in Drupal 8, or Services or RESTful Web Services in Drupal 7.
(Note: The Drupal 7 Services module itself does not require an update at this time, but you should still apply other contributed updates associated with this advisory if Services is in use.)
Updates
- 2019-02-22: Updated risk score given new information; see PSA-2019-02-22. The security risk score has been updated to 23/25 as there are now known exploits in the wild. In addition, any enabled REST resource end-point, even if it only accepts GET requests, is also vulnerable. Note this does not include REST exports from Views module.
