**Name of the Vulnerable Software and Affected Versions**
Barco ClickShare CX-20 Gen2 versions prior to 02.26.00.0008
**Description**
An issue exists in the Wallpaper Upload component within the `/wallpaper` file. Improper validation of the syntactic correctness of the `wallpaper` argument allows a remote attacker to cause a denial of service, which is a condition where the system becomes unavailable to its intended users.

Update Barco ClickShare CX-20 Gen2 to a version newer than 02.26.00.0007.
Restrict access to the `/wallpaper` file to minimize the risk of exploitation.
