Description
WatchGuard Dimension provides a client-side lock/unlock UI control for management changes. The server-side configuration endpoint does not enforce this lock/unlock workflow state, allowing an authenticated administrator to submit configuration changes directly to the endpoint without first completing the UI unlock step. This allows an authenticated read-write administrator session to bypass the intended editing workflow and overwrite configuration changes being made by another concurrent administrator session.
Affected products
- WatchGuard Dimension: from 2.0 before 2.3.1 — fixed in 2.3.1
How to fix
Upgrade to a fixed version: WatchGuard Dimension 2.3.1. Check the vendor advisory for mitigations.
