Technical Description
The Emerson DeltaV Distributed Control System (DCS) through 2022-04-29 mishandles authentication. It utilizes several proprietary protocols for a wide variety of functionality. These protocols include Firmware upgrade (18508/TCP, 18518/TCP); Plug-and-Play (18510/UDP); Hawk services (18507/UDP); Management (18519/TCP); Cold restart (18512/UDP); SIS communications (12345/TCP); and Wireless Gateway Protocol (18515/UDP). None of these protocols have any authentication features, allowing any attacker capable of communicating with the ports in question to invoke (a subset of) desired functionality.
Remediation
Check the references section for vendor advisories and patches from emerson. Update deltav_distributed_control_system to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
