Does this affect you?

It affects Toptech Systems RCU II+ and 1 other product. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

The RCU II+ and Multiload II+ are vulnerable to an unauthenticated service that exposes a debug interface granting full root-level access to the embedded system. This vulnerability stems from a network-accessible port running a Target Communications Framework (TCF) service that does not require any authentication, allowing an attacker to directly interact with the Linux environment that powers the device. Once connected, an attacker can freely view and modify the filesystem, manipulate running processes, and control network interfaces, enabling deep alteration of system behavior.
