Title: ABB Cylon Aspect 3.08.02 (webServerUpdate.php) Input Validation Config Poisoning
Advisory ID: ZSL-2025-5901
Type: Local/Remote
Impact: Security Bypass, Manipulation of Data, DoS
Risk: (5/5)
Release Date: 09.01.2025

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 ABB BMS/BAS controller suffers from improper input validation on the port POST parameter in the webServerUpdate.php script. This input is not validated on the server side and relies on bypassable client-side checks using the inString.js script to verify that the port parameter contains only characters from the set (0123456789). Attackers can bypass these checks and supply arbitrary integer values. Exploitation of this issue can result in configuration poisoning, Denial of Service (DoS) through malformed configurations, or manipulation of server settings via Cross-Site Request Forgery (CSRF) combined with authentication bypass.
