ABB ASPECT Building Management System versions 3.08.03 and earlier contain multiple critical vulnerabilities including SQL injection, command injection, file upload, privilege escalation, and cross-site scripting flaws across CWE-269, CWE-36, CWE-94, CWE-99, CWE-73, CWE-497, CWE-863, CWE-434, CWE-89, CWE-606, CWE-23, CWE-427, CWE-276, CWE-774, CWE-117, CWE-79, CWE-760, CWE-359, CWE-922, CWE-295, CWE-918, and CWE-257. These allow an authenticated attacker with high-privilege credentials to execute arbitrary code on the BMS and compromise building automation functions. NEXUS and MATRIX series have been patched in version 3.08.04 and later. ASPECT-Enterprise has reached end-of-life with no corrective updates planned; ABB is transitioning customers to a new cloud-based BMS platform.
What this means
What could happen
An authenticated attacker with high-privilege credentials could exploit multiple vulnerabilities to gain remote code execution on the Building Management System, potentially altering building automation settings, disabling alarms, or affecting HVAC, lighting, or other critical systems.
Who's at risk
Building management system operators using ABB ASPECT products should care, particularly those running NEXUS or MATRIX series units in commercial buildings (office, hospitality, healthcare, data centers) that depend on the BMS for HVAC, lighting, and facility automation. ASPECT-Enterprise users on end-of-life versions are at highest risk.
How it could be exploited
An attacker with engineering or administrative credentials could access the ASPECT web interface or API, then exploit SQL injection, command injection, file upload, or privilege escalation flaws to execute arbitrary code on the BMS server and modify building control logic or settings.
Prerequisites
Valid high-privilege ASPECT user credentials (engineering or administrative account)
Network access to the ASPECT web interface or API (typically ports 80/443)
ASPECT product version 3.08.03 or earlier
