FKIE_CVE-2025-59109

Vulnerability from fkie_nvd - Published: 2026-01-26 10:16 - Updated: 2026-01-27 07:16
Severity ?
5.1 (Medium) - CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
Summary
The dormakaba registration units 9002 (PIN Pad Units) have an exposed UART header on the backside. The PIN pad is sending every button press to the UART interface. An attacker can use the interface to exfiltrate PINs. As the devices are explicitly built as Plug-and-Play to be easily replaced, an attacker is easily able to remove the device, install a hardware implant which connects to the UART and exfiltrates the data exposed via UART to another system (e.g. via WiFi).
