An issue found in Directus API v.2.2.0 allows a remote attacker to cause a denial of service via a great amount of HTTP requests.

Directus is a free and open-source data platform for headless content management. The Directus process can be aborted by having an authorized user update the filenamedisk value to a folder and accessing that file through the /assets endpoint. This vulnerability has been patched and release v9.15.0 contains the fix. Users are advised to upgrade. Users unable to upgrade may prevent this problem by making sure no (untrusted) non-admin users have permissions to update the filenamedisk field on directusfiles.

Impact

The default value for the CORSENABLED and CORSORIGIN configuration was set to be very permissive by default. This could lead to unauthorized access in uncontrolled environments when the configuration hasn't been changed.

Patches

The default values for CORS have been changed in https://github.com/directus/directus/pull/12022 which is released under 9.7.0

Workarounds

Configure the CORS environment variables to match your project's usage, rather than leaving them at the (permissive) defaults.
