CKAN is an open-source data management system for powering data hubs and data portals. Multiple vulnerabilities have been discovered in Ckan which may lead to remote code execution. An 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`. 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. 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. All the above listed vulnerabilities have been fixed in CKAN 2.9.9 and CKAN 2.10.1. Users are advised to upgrade. There are no known workarounds for these issues.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

    (CVE-2023-32321)

According to its self-reported version number, the CKAN application running on the remote host is prior to 2.9.9 or 2.10.x prior to 2.10.1. It is, therefore, affected by multiples vulnerabilities :

- An 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. - A Remote code execution via unsafe pickle loading, via Beaker's session store when configured to use the file session store backend. - A Potential DOS due to lack of a length check on the resource id. - An 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. - A 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.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of CKAN installed on the remote host is prior to 2.9.9 or 2.10 prior to 2.10.1. It is, therefore, affected by a remote code execution vulnerability. A remote attacker 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
