Title: ABB Cylon Aspect 3.08.01 (jsonProxy.php) Information Disclosure
Advisory ID: ZSL-2024-5858
Type: Local/Remote
Impact: Security Bypass, Exposure of System Information, Exposure of Sensitive Information
Risk: (4/5)
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 unauthorized information disclosure. An unauthenticated attacker can retrieve sensitive system information, including system time, uptime, memory usage, and network load statistics. The jsonProxy.php endpoint proxies these requests to internal services without requiring authentication, allowing attackers to obtain detailed system status data, which could aid in further attacks by revealing operational characteristics and resource utilization.
