Pageflow has a membership edit feature which allows users to edit the roles of user memberships associated with an account that they have the manager
role to (including their own). While the Entity
dropdown select field is greyed out in the UI, an attacker can use tools which allow sending arbitrary HTTP request to craft a request to the /admin/users/{user_id}/memberships/{membership_id}
endpoint containing an additional membership[entity_id]
parameter. This parameter is honored when the membership is updated, allowing an attacker to update the membership object associated with their own account (with manager
role) to be associated with a different attacker-chosen account instead. Since account_id
s are enumerable, an attacker can compromise all accounts present on the platform.
Upgrade to version 15.7.1 or 14.5.2 of the pageflow
gem.
