A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.233.16-7862), Desigo PXC3 (All versions < V01.21.233.16-7862), Desigo PXC4 (All versions < V02.21.194.36-2715), Desigo PXC5.E003 (All versions < V02.21.194.36-2715), Desigo PXC5.E24 (All versions < V02.21.194.36-2715), Desigo PXC7 (All versions < V02.21.194.36-2715). The affected devices are vulnerable to a denial-of-service (DoS) vulnerability. An attacker can exploit this issue by sending a malformed BACnet packet, causing the device to stop responding to BACnet queries. Recovery requires a device reset or reboot to restore normal functionality.
