CKAN has an XSS vector in user uploaded images in group/org and user profiles

High severity GitHub Reviewed Published Feb 5, 2025 in ckan/ckan • Updated Feb 5, 2025

Package

pip ckan (pip)

Affected versions

< 2.10.7
>= 2.11.0, < 2.11.2

Patched versions

2.10.7
2.11.2

Description

Impact

Using a specially crafted file, a user could potentially upload a file containing code that when executed could send arbitrary requests to the server. If that file was opened by an administrator, it could lead to escalation of privileges of the original submitter or other malicious actions. Users must have been registered to the site to exploit this vulnerability.

Patches

This vulnerability has been fixed in CKAN 2.10.7 and 2.11.2

Workarounds

On versions prior to CKAN 2.10.7 and 2.11.2, site maintainers can restrict the file types supported for uploading using the ckan.upload.user.mimetypes / ckan.upload.user.types and ckan.upload.group.mimetypes / ckan.upload.group.types config options.
To entirely disable file uploads you can use:

ckan.upload.user.types = none

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
