Title: ABB Cylon Aspect 3.08.00 (log(Mix/Yum)Lookup.php) Off-by-One Error in Log Parsing
Advisory ID: ZSL-2024-5861
Type: Local/Remote
Impact: DoS, Exposure of System Information
Risk: (2/5)
Release Date: 05.11.2024
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
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.
