Vendor Solution
Toptech Systems provides two methods for remediating affected RCU II+ and Multiload II+ units: First, move the device to a closed or segmented network without untrusted access. Run one of the RCU II+/Multiload II+ Vulnerability Removal Tools (VRT) available at https://s3.amazonaws.com/docs.toptech.com/nonpublic/rcuiip_mliip_vrt.zip , https://s3.amazonaws.com/docs.toptech.com/nonpublic/rcuiip_mliip_vrt.gz. * This option does not require breaking Weights and Measures seals and has the least operational impact. Install the latest firmware from https://s3.amazonaws.com/docs.toptech.com/index.html#downloads/Firmware/RCUII+_MLII+_SMPII+/ . * This method requires stopping the bay and breaking the W&M seal. Be sure to back up the current ML configuration before performing the firmware update. For questions, contact Toptech Systems Support at security@toptech.com. Additional details are available in Toptech System's firmware vulnerability notice: https://s3.amazonaws.com/docs.toptech.com/nonpublic/2025%2012%2001%20RCU%20IIPlus%20MultiLoad%20IIPlus%20Vulnerability%20Notice.pdf .

| 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. | |
