Title: ABB Cylon Aspect 3.08.02 (escDevicesUpdate.php) Off-by-One Config Write DoS
Advisory ID: ZSL-2025-5902
Type: Local/Remote
Impact: Security Bypass, Manipulation of Data, DoS, Exposure of System Information
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

A vulnerability was identified in a PHP script where an off-by-one error in array access could lead to undefined behavior and potential DoS. The issue arises in a loop that iterates over an array using a < condition, allowing access to an out-of-bounds index. This can trigger errors or unexpected behavior when processing data, potentially crashing the application. Successful exploitation of this vulnerability can lead to a crash or disruption of service, especially if the script handles large data sets. This issue can be triggered via the rowCount POST parameter in the Electronic Security Control device update script.
