🛡️ CVE-2026-12562
Description
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.
How this vulnerability can be exploited
This issue can be reached from an adjacent network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
