BACnet Spoofing Vulnerability in WebCTRL Enables Unauthorized Control

Publication date: 2026-03-21

Last updated on: 2026-03-23

Assigner: ICS-CERT

Description
WebCTRL systems that communicate over BACnet inherit the protocol's lack of network layer authentication. WebCTRL does not implement additional validation of BACnet traffic so an attacker with network access could spoof BACnet packets directed at either the WebCTRL server or associated AutomatedLogic controllers. Spoofed packets may be processed as legitimate.

Executive Summary

This vulnerability affects WebCTRL systems that communicate using the BACnet protocol. BACnet lacks network layer authentication, and WebCTRL does not add any extra validation for BACnet traffic. As a result, an attacker with access to the network can spoof BACnet packets, making them appear legitimate to the WebCTRL server or associated AutomatedLogic controllers.

Impact Analysis

An attacker exploiting this vulnerability could send spoofed BACnet packets that the WebCTRL system or its controllers might accept as valid. This could lead to unauthorized manipulation or control of the system, potentially causing operational disruptions or malicious interference.
