Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
