AI-suggested

If you cannot patch yet, administrators should consider network-level controls to restrict unauthorized BACnet traffic to these devices. Monitoring for unusual BACnet traffic patterns may help detect exploitation attempts. Manual device reset or reboot is required to recover from the DoS condition.

Description

A denial-of-service (DoS) vulnerability exists in multiple Siemens Desigo devices, including DXR2, PXC3, PXC4, PXC5.E003, PXC5.E24, and PXC7. The issue is triggered by sending a malformed BACnet packet, causing the affected device to stop responding to BACnet queries. Recovery requires a manual device reset or reboot. The vulnerability affects versions prior to V01.21.233.16-7862 for DXR2 and PXC3, and prior to V02.21.194.36-2715 for PXC4, PXC5.E003, PXC5.E24, and PXC7. The CVSS score is 4.3, indicating a medium severity impact focused on availability.
