First published: Thu Jan 16 2020(Updated: )
A vulnerability has been identified in APOGEE MEC/MBC/PXC (P2) (All versions < V2.8.2), APOGEE PXC Series (BACnet) (All versions < V3.5.3), APOGEE PXC Series (P2) (All versions >= V2.8.2 and < V2.8.19), Desigo PXC00-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC00-U (All versions >= V2.3x and < V6.00.327), Desigo PXC001-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC100-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC12-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC128-U (All versions >= V2.3x and < V6.00.327), Desigo PXC200-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC22-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC22.1-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC36.1-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC50-E.D (All versions >= V2.3x and < V6.00.327), Desigo PXC64-U (All versions >= V2.3x and < V6.00.327), Desigo PXM20-E (All versions >= V2.3x and < V6.00.327), Nucleus NET (All versions), Nucleus RTOS (All versions), Nucleus ReadyStart for ARM, MIPS, and PPC (All versions < V2017.02.2 with patch "Nucleus 2017.02.02 Nucleus NET Patch"), Nucleus SafetyCert (All versions), Nucleus Source Code (All versions), SIMOTICS CONNECT 400 (All versions < V0.3.0.330), TALON TC Series (BACnet) (All versions < V3.5.3), VSTAR (All versions). By sending specially crafted DHCP packets to a device where the DHCP client is enabled, an attacker could change the IP address of the device to an invalid value. The vulnerability could affect availability and integrity of the device. Adjacent network access is required, but no authentication and no user interaction is needed to conduct an attack.
