Title: ABB Cylon Aspect 3.08.01 (jsonProxy.php) Denial of Service
Advisory ID: ZSL-2024-5856
Type: Local/Remote
Impact: Security Bypass, DoS
Risk: (5/5)
Release Date: 30.10.2024

Summary

ASPECT is an award-winning scalable building energy management and control solution designed to allow users seamless access to their building data through standard building protocols including smart devices.

Description

The jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable to an unauthenticated Denial of Service (DoS) attack. An attacker can remotely restart the main Java server by accessing the FTControlServlet with the restart parameter. The endpoint proxies requests to localhost without requiring authentication, enabling attackers to disrupt system availability by repeatedly triggering server restarts.
