Descriptions

Cosy+ devices running a firmware 21.x below 21.2s10 or a firmware 22.x below 22.1s3 are vulnerable to code injection due to improper parameter blacklisting. This is fixed in version 21.2s10 and 22.1s3.

The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. Due to improper neutralization of parameters read from a user-controlled configuration file, an authenticated attacker is able to inject and execute OS commands on the device.
