Summary

Unauthenticated db-file-storage views

Details

Impact

In Nautobot 1.x and 2.0.x, the URLs /files/get/?name=... and /files/download/?name=... are used to provide admin access to files that have been uploaded as part of a run request for a Job that has FileVar inputs. Under normal operation these files are ephemeral and are deleted once the Job in question runs.

It was reported by @kircheneer that in the default implementation used in Nautobot, as provided by django-db-file-storage, these URLs do not by default require any user authentication to access; they should instead be restricted to only users who have permissions to view Nautobot's FileProxy model instances.

Note that no URL mechanism is provided for listing or traversal of the available file name values, so in practice an unauthenticated user would have to guess names to discover arbitrary files for download, but if a user knows the file name/path value, they can access it without authenticating, so we are considering this a vulnerability.

Patches

Fixes will be included in Nautobot 1.6.7 and Nautobot 2.0.6.

Workarounds

No workaround other than applying the patches included in https://github.com/nautobot/nautobot/pull/4959/files (2.0.x) or https://github.com/nautobot/nautobot/pull/4964/files (1.6.x)
