CVE-2025-2410: ASPECT Port Manipulation Vulnerability

CVE-2025-2410 Overview

CVE-2025-2410 is a port manipulation vulnerability affecting ABB's ASPECT, NEXUS, and MATRIX building automation and energy management systems. This vulnerability allows attackers to control TCP/IP port access when session administrator credentials become compromised. The flaw falls under CWE-99 (Improper Control of Resource Identifiers), indicating that the affected systems fail to properly validate or restrict resource identifiers used for network port configurations.

Building automation systems like ASPECT are critical infrastructure components used in commercial and industrial facilities to manage energy, HVAC, lighting, and security systems. Successful exploitation could allow attackers to manipulate network communications, potentially disrupting building operations or gaining further access to connected systems.

Critical Impact

Attackers with compromised administrator credentials can manipulate TCP/IP port configurations, potentially enabling unauthorized network access, traffic interception, or disruption of building automation services.

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-2025-2410

Vulnerability Analysis

This vulnerability enables port manipulation attacks against ABB building automation controllers when an attacker gains access to session administrator credentials. The root issue lies in improper control of resource identifiers (CWE-99), where the system fails to adequately validate or restrict the manipulation of TCP/IP port configurations.

Building automation systems typically expose management interfaces over the network for configuration and monitoring purposes. When administrator credentials are compromised through credential theft, brute-force attacks, or social engineering, attackers can leverage this vulnerability to modify port access settings. This could enable them to open unauthorized network ports, redirect traffic, or block legitimate communications.

The network-based attack vector means exploitation can occur remotely, though it requires prior compromise of privileged administrator credentials. Once exploited, attackers gain the ability to impact confidentiality, integrity, and availability of both the targeted system and potentially connected systems within the building automation network.

Root Cause

The vulnerability stems from improper control of resource identifiers (CWE-99) within the ASPECT, NEXUS, and MATRIX firmware. The affected systems do not implement sufficient validation or restrictions on TCP/IP port configuration operations, allowing authenticated administrators to manipulate network port access in ways that could be abused by attackers who have obtained administrator credentials.

This design weakness means that once administrator-level access is achieved, there are insufficient safeguards to prevent malicious port manipulation activities that could compromise network security boundaries.

Attack Vector

The attack requires network access to the target device and valid administrator session credentials. An attacker would typically:

1. Obtain administrator credentials through credential theft, phishing, or exploitation of weak authentication
2. Authenticate to the ASPECT/NEXUS/MATRIX management interface
3. Leverage the port manipulation vulnerability to modify TCP/IP port access configurations
4. Use the modified port access to establish persistent access, intercept traffic, or disrupt services

The vulnerability mechanism involves improper validation of port configuration parameters, allowing manipulation of network access controls. Refer to the ABB Technical Document for detailed technical specifications.

Detection Methods for CVE-2025-2410

Indicators of Compromise

• Unexpected changes to TCP/IP port configurations on ASPECT, NEXUS, or MATRIX devices
• Unauthorized network ports opened or closed on building automation controllers
• Suspicious administrator login activity, especially from unusual IP addresses or at unusual times
• Network traffic anomalies indicating port scanning or unauthorized access attempts targeting building automation systems

Detection Strategies

• Monitor authentication logs for administrator account access patterns and failed login attempts
• Implement network monitoring to detect unexpected port state changes on building automation systems
• Deploy intrusion detection systems (IDS) with signatures for ABB ASPECT/NEXUS/MATRIX management traffic anomalies
• Establish baselines for normal port configurations and alert on deviations

Monitoring Recommendations

• Enable comprehensive logging on all ASPECT, NEXUS, and MATRIX devices and forward logs to a centralized SIEM
• Implement real-time alerting for administrator-level authentication events
• Monitor network traffic to and from building automation systems for unexpected connections
• Conduct regular configuration audits to detect unauthorized port modifications

How to Mitigate CVE-2025-2410

Immediate Actions Required

• Audit all administrator accounts on affected ABB devices and reset credentials
• Implement strong, unique passwords for all administrator accounts
• Enable multi-factor authentication if supported by the device firmware
• Segment building automation networks from general corporate networks using firewalls and VLANs
• Review and restrict network access to management interfaces

Patch Information

ABB has published a security advisory addressing this vulnerability. Organizations should consult the ABB Technical Document for detailed patch information and upgrade guidance. Upgrade affected ASPECT-Enterprise, NEXUS Series, and MATRIX Series devices to firmware versions newer than 3.08.03 when available.

Workarounds

• Restrict network access to management interfaces using firewall rules, allowing connections only from trusted management stations
• Implement network segmentation to isolate building automation systems from untrusted networks
• Deploy a VPN for remote management access rather than exposing management interfaces directly
• Monitor for and alert on configuration changes to detect potential exploitation attempts
• Consider disabling remote management access if not operationally required

# Example firewall rules to restrict management access (adjust IPs and ports as needed)
# Allow management access only from trusted admin workstation
iptables -A INPUT -p tcp --dport 443 -s 192.168.10.50 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP

# Log dropped connection attempts for monitoring
iptables -A INPUT -p tcp --dport 443 -j LOG --log-prefix "ABB_MGMT_BLOCKED: "
