Any community or collection administrator can escalate their permission up to become system administrator.
This vulnerability only existed in 7.0 and does not impact 6.x or below.
Fix is included in 7.1. Please upgrade to 7.1 at your earliest convenience.
In 7.0, temporarily disable the ability for community or collection administrators to manage permissions or workflows settings, i.e. set the following properties in your local.cfg / dspace.cfg file
core.authorization.collection-admin.policies = false
core.authorization.community-admin.policies = false
core.authorization.community-admin.collection.workflows = false
Once upgraded to 7.1, these settings can be safely reverted to the default values of true
.
