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.\n\n## Affected packages\n\n- `ckan < 2.9.9`\n- `ckan`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `ckan 2.9.9`","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.3,"exploitation":0,"ransomware":0},"changes":[]}
