Barco ClickShare Huddle CS-100 devices before 1.9.0 and CSE-200 devices before 1.9.0 have incorrect Credentials Management. The ClickShare Base Unit implements encryption at rest using encryption keys which are shared across all ClickShare Base Units of models CS-100 & CSE-200.

On Barco ClickShare Button R9861500D01 devices (before firmware version 1.9.0) JTAG access is disabled after ROM code execution. This means that JTAG access is possible when the system is running code from ROM before handing control over to embedded firmware.

Barco ClickShare Button R9861500D01 devices before 1.9.0 have Insufficiently Protected Credentials. The root account (present for access via debug interfaces, which are by default not enabled on production devices) of the embedded Linux on the ClickShare Button is using a weak password.

Barco ClickShare Button R9861500D01 devices before 1.9.0 have Improper Following of a Certificate's Chain of Trust. The embedded 'dongle_bridge' program used to expose the functionalities of the ClickShare Button to a USB host, does not properly validate the whole certificate chain.

Barco ClickShare Button R9861500D01 devices before 1.9.0 allow Information Exposure. The encrypted ClickShare Button firmware contains the private key of a test device-certificate.

Barco ClickShare Button R9861500D01 devices before 1.9.0 allow OS Command Injection. The embedded 'dongle_bridge' program used to expose the functionalities of the ClickShare Button to a USB host, is vulnerable to OS command injection vulnerabilities. These vulnerabilities could lead to code execution on the ClickShare Button with the privileges of the user 'nobody'.

An issue was discovered on Barco ClickShare CSE-200 and CS-100 Base Units with firmware before 1.6.0.3. Sending an arbitrary unexpected string to TCP port 7100 respecting a certain frequency timing disconnects all clients and results in a crash of the Unit.
