SSA-718393: Partial Denial of Service Vulnerability in APOGEE PXC and TALON TC Series (BACnet) Devices

APOGEE PXC and TALON TC Series (BACnet) Devices devices start sending unsolicited BACnet broadcast messages after processing a specific BACnet createObject request. This could allow an attacker residing in the same BACnet network to send a specially crafted message that results in a partial denial of service condition of the targeted device, and potentially reduce the availability of BACnet network. A power cycle is required to restore the device's normal operation.

Siemens recommends countermeasures for products where fixes are not, or not yet available.
