A session management vulnerability exists in the Legacy UI Reduced Function Login feature of NT-ware uniFLOW Online. Under specific timing conditions during Service Offline Emergency Mode, a previously authenticated session may be retained after logout, which could allow a subsequent user to be authenticated as the previous user and gain unauthorised limited access to device functionality.

The registration process of uniFLOW Online (NT-ware product) apps, prior to and including version 2024.1.0, can be compromised when email login is enabled on the tenant. Those tenants utilising email login in combination with Microsoft Safe Links or similar are impacted. This vulnerability may allow the attacker to register themselves against a genuine user in the system and allow malicious users with similar access and capabilities via the app to the existing genuine user.
