Barco ClickShare Button R9861500D01 devices before 1.9.0 allow Information exposure (issue 2 of 2).. The encryption key of the media content which is shared between a ClickShare Button and a ClickShare Base Unit is randomly generated for each new session and communicated over a TLS connection. An attacker who is able to perform a Man-in-the-Middle attack between the TLS connection, is able to obtain the encryption key.

Barco ClickShare Button R9861500D01 devices before 1.9.0 have incorrect Credentials Management. The ClickShare Button implements encryption at rest which uses a one-time programmable (OTP) AES encryption key. This key is shared across all ClickShare Buttons of model R9861500D01.

Barco ClickShare Button R9861500D01 devices before 1.10.0.13 have Missing Support for Integrity Check. The Barco signed 'Clickshare_For_Windows.exe' binary on the ClickShare Button (R9861500D01) loads a number of DLL files dynamically without verifying their integrity.

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.

Barco ClickShare Button R9861500D01 devices before 1.10.0.13 have Missing Support for Integrity Check. The ClickShare Button does not verify the integrity of the mutable content on the UBIFS partition before being used.

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'.

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.

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 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.

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.

A command injection was identified on Barco ClickShare Base Unit devices with CSM-1 firmware before 1.7.0.3 and CSC-1 firmware before 1.10.0.10. An attacker with access to the product's web API can exploit this vulnerability to completely compromise the vulnerable device.

An issue was discovered in Barco ClickShare CSM-1 firmware before v1.7.0.3 and CSC-1 firmware before v1.10.0.10. An authenticated user can manage the wallpaper collection in the webUI to be shown as background on the ClickShare product. By uploading a wallpaper with a specially crafted name, an HTML injection can be triggered as special characters are not neutralized before output.

Barco ClickShare CSC-1 devices with firmware before 01.09.03 allow remote attackers to obtain the root password by downloading and extracting the firmware image.

Directory traversal vulnerability in the wallpaper parsing functionality in Barco ClickShare CSC-1 devices with firmware before 01.09.03, CSM-1 devices with firmware before 01.06.02, and CSE-200 devices with firmware before 01.03.02 allows remote attackers to read /etc/shadow via unspecified vectors.

Cross-site scripting (XSS) vulnerability in wallpaper.php in the Base Unit in Barco ClickShare CSC-1 devices with firmware before 01.09.03, CSM-1 devices with firmware before 01.06.02, and CSE-200 devices with firmware before 01.03.02 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Barco ClickShare CSC-1 devices with firmware before 01.09.03 and CSM-1 devices with firmware before 01.06.02 allow remote attackers to execute arbitrary code via unspecified vectors.
