{"schema":"threatline.record/2","record":{"id":"CVE-2023-32321","aliases":["GHSA-446m-hmmm-hm8m","PYSEC-2026-312"],"summary":"Ckan remote code execution and private information access via crafted resource ids","details":"Specific vulnerabilities:\n\n* Arbitrary file write in `resource_create` and `package_update` actions, using the `ResourceUploader` object.  Also reachable via `package_create`, `package_revise`, and `package_patch` via calls to `package_update`.\n* Remote code execution via unsafe pickle loading, via Beaker's session store when configured to use the file session store backend.\n* Potential DOS due to lack of a length check on the resource id.\n* 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.\n* 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.  \n\n### Impact\n\nA 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. \n\n### Patches\n\nAll the above listed vulnerabilities have been fixed in CKAN 2.9.9 and CKAN 2.10.1\nThe patches for CKAN 2.9 should apply easily to previous CKAN versions.","categories":["Libraries & packages"],"product":"ckan","vendor":"ckan","ecosystem":"pip","affected_ranges":[{"source":"GitHub Advisory
