Description
A vulnerability exists in serial device servers where active debug code remains enabled in the UART interface. An attacker with physical access to the device can directly connect to the UART interface and, without authentication, user interaction, or execution conditions, gain unauthorized access to internal debug functionality. Exploitation is low complexity and allows an attacker to execute privileged operations and access sensitive system resources, resulting in a high impact to the confidentiality, integrity, and availability of the affected device. No security impact to external or dependent systems has been identified.

What to do
Workaround: * For the NPort 5000 Series, make sure that the physical protection of the NPort devices and/or the system meets the security needs of your application. By limiting physical access to authorized personnel, you significantly reduce the risk of local cyberattacks. Please refer to The Security Hardening Guide for NPort 5000 Series (v2.4 or later) https://www.moxa.com/en/products/industrial-edge-connectivity/serial-device-servers/general-device-servers/nport-5100-series#resources for more information.
