Description

A flaw was found in rubygem-katello. An SQL injection vulnerability exists in the Red Hat Satellite Katello Registry Proxy. The application fails to sanitize input parameters used in database queries within the RegistryProxiesController. The methods check_blob_push_org_label and get_matching_products_from_org take user-supplied labels directly from the request path and interpolate them into raw SQL fragments. This flaw is accessible to a user with only the create_personal_access_tokens permission, even if the user access is restricted, with no Organization or Location assigned.
