A low privileged remote attacker can use the ssh feature to execute commands directly after login. The process stays open and uses resources which leads to a reduced performance of the management functions. Switching functionality is not affected.

An XSS vulnerability in dyn_conn.php can be used by an unauthenticated remote attacker to trick an authenticated user to send a manipulated POST request to the device in order to change parameters available via web based management (WBM). The vulnerability does not provide access to system-level resources such as operating system internals or privileged functions. Access is limited to device configuration parameters that are available in the context of the web application. The session cookie is secured by the httpOnly Flag. Therefore an attacker is not able to take over the session of an authenticated user.

A physical attacker with access to the device display via USB-C can send a message to the device which triggers an unsecure copy to a buffer resulting in loss of integrity and a temporary denial-of-service for the stations until they got restarted by the watchdog.
