CVE-2019-6340

Ein Angreifer kann mehrere Schwachstellen in Drupal Core ausnutzen, um beliebigen Programmcode auszuführen, Cross-Site-Scripting-Angriffe durchzuführen, um Daten zu manipulieren, oder um Nutzer auf bösartige Websites umzuleiten.

Some field types do not properly sanitize data from non-form sources in Drupal 8.5.x before 8.5.11 and Drupal 8.6.x before 8.6.10. 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 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 apply other contributed updates associated with this advisory if Services is in use.)

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](https://www.drupal.org/project/jsonapi) in Drupal 8, or [Services](https://www.drupal.org/project/services) or [RESTful Web Services](https://www.drupal.org/project/restws) 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](https://www.drupal.org/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.
