InvenioRDM v6.0.5¶

2021-12-06

InvenioRDM v6.0.5 is a bug fix releases that fixes a moderate severity vulnerability in earlier versions of InvenioRDM.

Vulnerability fix¶

Permissions not properly checked when a record is published¶

Impact

Invenio-Drafts-Resources does not properly check permissions when a record is published. The vulnerability is exploitable in a default installation of InvenioRDM. An authenticated user is able via REST API calls to publish draft records of other users if they know the record identifier and the draft validates (e.g. all require fields filled out). An attacker is not able to modify the data in the record, and thus e.g. cannot change a record from restricted to public.

Details

The service's publish() method contains the following permission check:

def publish(..):
    self.require_permission(identity, "publish")

However, the record should have been passed into the permission check so that the need generators have access to e.g. the record owner.

def publish(..):
    self.require_permission(identity, "publish", record=record)

The bug is activated in Invenio-RDM-Records which has a need generator called RecordOwners(), which when no record is passed in defaults to allow any authenticated user:

class RecordOwners(Generator):
    def needs(self, record=None, **kwargs):
        if record is None:
            return [authenticated_user]
    # ...

Patches

The problem is patched in Invenio-Drafts-Resources v0.13.7 and 0.14.6+, which is part of InvenioRDM v6.0.1 and InvenioRDM v7.0 respectively.

You can verify the version installed of Invenio-Drafts-Resources via PIP:

$ cd ~/src/my-site
$ pipenv run pip freeze | grep invenio-drafts-resources
invenio-drafts-resources==0.13.7
