Title: ABB Cylon Aspect 3.08.02 (aspectMemory.php) Arbitrary Heap Memory Configuration
Advisory ID: ZSL-2024-5883
Type: Local/Remote
Impact: Manipulation of Data, DoS
Risk: (4/5)
Release Date: 13.12.2024

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

An authenticated access vulnerability in the aspectMemory.php script of ABB Cylon Aspect BMS/BAS controllers allows attackers to set arbitrary values for Java heap memory parameters (HEAPMIN and HEAPMAX). This configuration is written to /usr/local/aam/etc/javamem. The absence of input validation can lead to system performance degradation, Denial-of-Service (DoS) conditions, and crashes of critical Java applications.
