CVE-2024-51554
📋 TL;DR
CVE-2024-51554 is a default credential vulnerability in ABB ASPECT products on Linux that allows attackers to gain unauthorized access using publicly known default credentials. This affects ABB ASPECT Enterprise, NEXUS Series, and MATRIX Series version 3.08.02. Organizations using these products with default credentials are vulnerable to complete system compromise.
💻 Affected Systems
- ABB ASPECT - Enterprise
- NEXUS Series
- MATRIX Series
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover allowing attackers to modify configurations, steal sensitive data, disrupt industrial operations, or use the system as a foothold for lateral movement.
Likely Case
Unauthorized access to the ASPECT system enabling configuration changes, data exfiltration, and potential disruption of monitoring/control functions.
If Mitigated
Limited impact if strong network segmentation and access controls prevent external access to the vulnerable interface.
🎯 Exploit Status
Exploitation requires knowledge of default credentials but no technical complexity. Credentials are likely documented in public sources.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for updated version
Vendor Advisory: https://search.abb.com/library/Download.aspx?DocumentID=9AKK108469A7497&LanguageCode=en&DocumentPartId=&Action=Launch
Restart Required: Yes
Instructions:
1. Review ABB advisory for specific patch details. 2. Apply vendor-recommended updates. 3. Change all default credentials. 4. Restart affected systems.
🔧 Temporary Workarounds
Change Default Credentials
linuxImmediately change all default passwords and usernames on affected ASPECT systems
# Use ASPECT administration interface to change credentials
# No single command - use product-specific admin tools
Network Segmentation
linuxRestrict network access to ASPECT systems using firewalls and VLANs
# Example iptables rule to restrict access
iptables -A INPUT -p tcp --dport [ASPECT_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [ASPECT_PORT] -j DROP
🧯 If You Can't Patch
- Implement strict network access controls to isolate ASPECT systems from untrusted networks
- Enable multi-factor authentication if supported and monitor for unauthorized access attempts
🔍 How to Verify
Check if Vulnerable:
Attempt to authenticate to the ASPECT system using known default credentials. Check if default credentials are still in use via system configuration review.Check Version:
# Check ASPECT version through product interface or configuration filesVerify Fix Applied:
Verify that default credentials no longer work and only strong, unique credentials provide access. Confirm patch version matches vendor recommendations.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful login
- Multiple login attempts from unusual IP addresses
- Configuration changes from unexpected users
Network Indicators:
- Authentication traffic to ASPECT systems from unauthorized networks
- Brute force patterns against ASPECT authentication endpoints
SIEM Query:
source="ASPECT" AND (event_type="authentication" AND result="success") AND user="default" OR user="admin"
