Descriptions

Insecure Permission vulnerability in Cosy+ devices running a firmware 21.x below 21.2s10 or a firmware 22.x below 22.1s3 are executing several processes with elevated privileges.

The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. The Ewon Cosy+ executes all tasks and services in the context of the user "root" and therefore with the highest system privileges. By compromising a single service, attackers automatically gain full system access.
