ABB Cylon Aspect 3.08.01 (oosManagerAjax.php) Information Manipulation


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.01

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 BMS/BAS controller suffers from an unauthenticated information
disclosure and manipulation vulnerability in the OOS (Out of Service) Manager.
An unauthorized attacker can enumerate devices marked as in or out of service,
accessing detailed information such as device names, network IDs, and transaction
counts. Furthermore, the attacker can exploit this vulnerability to modify the
OOS status of devices, allowing unauthorized additions or updates via the exposed
functionality of the /oosManagerAjax.php endpoint.
