<html><body><p>ABB Cylon Aspect 3.08.01 (jsonProxy.php) Username Enumeration
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 jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable
to username enumeration. An unauthenticated attacker can interact with the
UserManager servlet to enumerate valid usernames on the system. Since jsonProxy.php
proxies requests to internal services without requiring authentication, attackers
can gain unauthorized insights into valid usernames.
