Ckan remote code execution and private information access via crafted resource ids
Specific vulnerabilities:
- Arbitrary file write in
resource_createandpackage_updateactions, using theResourceUploaderobject. Also reachable viapackage_create,package_revise, andpackage_patchvia calls topackage_update. - Remote code execution via unsafe pickle loading, via Beaker's session store when configured to use the file session store backend.
- Potential DOS due to lack of a length check on the resource id.
- Information disclosure: A user with permission to create a resource can access any other resource on the system if they know the id, even if they don't have access to it.
- Resource overwrite: A user with permission to create a resource can overwrite any resource if they know the id, even if they don't have access to it.
Impact
A user with permissions to create or edit a dataset can upload a resource with a specially crafted id to write the uploaded file in an arbitrary location. This can be leveraged to Remote Code Execution via Beaker's insecure pickle loading.
Patches
All the above listed vulnerabilities have been fixed in CKAN 2.9.9 and CKAN 2.10.1 The patches for CKAN 2.9 should apply easily to previous CKAN versions.
