Barco wePresent WiPG-1600W firmware includes a hardcoded API account and password that is discoverable by inspecting the firmware image. A malicious actor could use this password to access authenticated, administrative functions in the API. Affected Version(s): 2.5.1.8, 2.5.0.25, 2.5.0.24, 2.4.1.19.

CVE-2020-28330
Barco wePresent WiPG-1600W devices have Unprotected Transport of Credentials. Affected Version(s): 2.5.1.8. An attacker armed with hardcoded API credentials (retrieved by exploiting CVE-2020-28329) can issue an authenticated query to display the admin password for the main web user interface listening on port 443/tcp of a Barco wePresent WiPG-1600W device.
CVE-2020-28331
Barco wePresent WiPG-1600W devices have Improper Access Control. Affected Version(s): 2.5.1.8. The Barco wePresent WiPG-1600W device has an SSH daemon included in the firmware image. By default, the SSH daemon is disabled and does not start at system boot. The system initialization scripts read a device configuration file variable to see if the SSH daemon should be started. The web interface does not provide a visible capability to alter this configuration file variable. However, a malicious actor can include this variable in a POST such that the SSH daemon will be started when the device boots.
CVE-2020-28332
Barco wePresent WiPG-1600W devices download code without an Integrity Check. Affected Version(s): 2.5.1.8, 2.5.0.25, 2.5.0.24, 2.4.1.19. The Barco wePresent WiPG-1600W firmware does not perform verification of digitally signed firmware updates and is susceptible to processing and installing modified/malicious images.
CVE-2020-28333
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. Instead, the web interface uses a “SEID” token that is appended to the end of URLs in GET requests. Thus the “SEID” would be exposed in web proxy logs and browser history. 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.
CVE-2020-28334
Barco wePresent WiPG-1600W devices use Hard-coded Credentials (issue 2 of 2). Affected Version(s): 2.5.1.8, 2.5.0.25, 2.5.0.24, 2.4.1.19. The Barco wePresent WiPG-1600W device has a hardcoded root password hash included in the firmware image. Exploiting CVE-2020-28329, CVE-2020-28330 and CVE-2020-28331 could potentially be used in a simple and automated exploit chain to go from unauthenticated remote attacker to root shell.
