Title: ABB Cylon Aspect 3.08.01 (calendarFileDelete.php) Arbitrary File Deletion
Advisory ID: ZSL-2024-5836
Type: Local/Remote
Impact: Manipulation of Data, DoS
Risk: (5/5)
Release Date: 07.10.2024

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 BMS/BAS controller suffers from an arbitrary file deletion vulnerability. Input passed to the 'file' parameter in calendarFileDelete.php is not properly sanitised before being used to delete calendar files. This can be exploited by an unauthenticated attacker to delete files with the permissions of the web server using directory traversal sequences passed within the affected POST parameter.
