Barco wePresent WiPG-1600W devices allow Authentication Bypass. Affected Version(s): 2.5.1.8. The Barco wePresent WiPG-1600W web interface does not use session cookies for tracking authenticated sessions.

An attacker that is able to capture the "SEID" and originate requests from the same IP address (via a NAT device or web proxy) would be able to access the user interface of the device without having to know the credentials.
