CVE-2025-30169 Overview
CVE-2025-30169 is a file upload vulnerability affecting ABB ASPECT building management products. An authenticated attacker with compromised administrator session credentials can upload and execute arbitrary PHP scripts on the device. The flaw is categorized as Unrestricted Upload of File with Dangerous Type [CWE-434].
The vulnerability affects ASPECT-Enterprise, NEXUS Series, and MATRIX Series firmware through version 3.08.03. Successful exploitation enables script injection on the underlying system, impacting integrity and availability of the building automation controller.
Critical Impact
An attacker holding valid administrator session credentials can upload PHP payloads that execute on the ASPECT controller, enabling persistence and manipulation of building automation functions.
Affected Products
- ABB ASPECT-Enterprise through version 3.08.03
- ABB NEXUS Series through version 3.08.03
- ABB MATRIX Series through version 3.08.03

Technical Details for CVE-2025-30169
Vulnerability Analysis
The vulnerability resides in the file upload handling of ASPECT's web-based administration interface. The application accepts uploaded files without enforcing restrictions on file type or executable content. An authenticated administrator can upload a PHP script and trigger its execution within the web server context.
Because ASPECT, NEXUS, and MATRIX devices run building management workloads, code execution on the controller can disrupt HVAC, lighting, and energy systems. The attacker gains the ability to issue system-level commands, exfiltrate configuration data, and modify automation logic.
Root Cause
The root cause is missing validation of uploaded file types and locations [CWE-434]. The upload handler does not restrict dangerous extensions such as .php, nor does it store files outside the web root. Uploaded scripts remain directly reachable through HTTP requests, allowing server-side interpretation.
Attack Vector
Exploitation requires network access to the ASPECT management interface and valid administrator session credentials. Credentials may be obtained through phishing, credential reuse, or session hijacking. After authenticating, the attacker submits a crafted multipart upload containing a PHP payload and then issues an HTTP request to execute it. No user interaction is required beyond the initial authenticated session.
No verified public exploit code is available. See the ABB security advisory for vendor-published technical details.

Stop Exploit AttemptsDetection Methods for CVE-2025-30169
Indicators of Compromise
- Unexpected .php or other script files appearing in ASPECT web-accessible directories.
- HTTP POST requests to administrative upload endpoints originating from unusual IP addresses or at off-hours.
- Outbound connections from ASPECT, NEXUS, or MATRIX devices to unknown external hosts following administrator login events.
- New or modified cron jobs, scheduled tasks, or system files on the controller.
Detection Strategies
- Monitor administrator authentication events on ASPECT management interfaces for anomalous source IPs or geolocations.
- Inspect web server access logs for POST requests to file upload handlers followed by GET requests to uploaded filenames.
- Deploy file integrity monitoring on web root directories of affected devices to flag new executable content.
Monitoring Recommendations
- Forward ASPECT device logs to a centralized SIEM for correlation of upload activity with authentication events.
- Alert on any process spawned by the web server that invokes shells, interpreters, or system utilities.
- Baseline normal administrator workflows and investigate deviations such as off-hours uploads or new file extensions.
How to Mitigate CVE-2025-30169
Immediate Actions Required
- Rotate all ASPECT, NEXUS, and MATRIX administrator credentials and invalidate active sessions.
- Restrict network access to the management interface to trusted administrative subnets or VPN only.
- Audit web root directories on affected devices for unauthorized script files and remove any that are discovered.
- Enable multi-factor authentication where supported and enforce strong password policies.
Patch Information
ABB has published a security advisory covering CVE-2025-30169. Administrators should consult the ABB document portal for firmware updates beyond version 3.08.03 and apply them to all affected ASPECT-Enterprise, NEXUS Series, and MATRIX Series devices.
Workarounds
- Isolate ASPECT, NEXUS, and MATRIX controllers on dedicated OT network segments with strict firewall rules.
- Disable or block direct Internet exposure of the device web interface.
- Enforce session timeouts and limit concurrent administrator sessions to reduce credential compromise impact.
# Example firewall rule restricting ASPECT admin interface to a management subnet
iptables -A INPUT -p tcp --dport 443 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
