Overview
ckan is a world’s leading Open Source data portal platform.
It powers dozens of Open Data portals around the world, including data.gov, open.canada.ca and europeandataportal.eu but also regional, research and community organizations.
It makes easy to publish, share and find data online and is fully customizable via extensions and plugins.
Affected versions of this package are vulnerable to Arbitrary File Upload. A user with permissions to create or edit a dataset can upload a resource with a specially crafted resource ID to write the uploaded file in an arbitrary location using path traversal. The arbitrary file write is in the resource_create and package_update actions, using the ResourceUploader object. It is also reachable via package_create, package_revise, and package_patch via calls to package_update. Arbitrary files can also be read this way, if the user knows the ID of the desired file.
This may enable remote code execution via Beaker's insecure pickle loading when configured to use the file session store backend.
Denial of service may be possible by passing a resource ID of excessive length.
