CVE-2024-4007
📋 TL;DR
This vulnerability involves default credentials in ABB ASPECT, NEXUS, and MATRIX Series version 3.07 install packages. Attackers can exploit this to log into product instances that have been incorrectly configured, potentially gaining unauthorized access to industrial control systems. Organizations using these ABB products with default or unchanged credentials are affected.
💻 Affected Systems
- ABB ASPECT Series
- ABB NEXUS Series
- ABB MATRIX Series
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to manipulate industrial processes, cause physical damage, disrupt operations, or exfiltrate sensitive industrial data.
Likely Case
Unauthorized access to control systems enabling configuration changes, data theft, or disruption of industrial operations.
If Mitigated
Limited impact if proper credential management and network segmentation are implemented, though default credentials remain a risk.
🎯 Exploit Status
Exploitation requires knowledge of default credentials and network access to vulnerable systems. No authentication needed beyond credential guessing.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in references, but vendor advisory recommends updates
Vendor Advisory: https://search.abb.com/library/Download.aspx?DocumentID=9AKK108469A6101&LanguageCode=en&DocumentPartId=&Action=Launch
Restart Required: Yes
Instructions:
1. Download and apply the latest patch from ABB's advisory. 2. Change all default credentials to strong, unique passwords. 3. Restart affected systems to apply changes. 4. Verify credentials are updated and systems are secure.
🔧 Temporary Workarounds
Change Default Credentials
allImmediately change all default passwords to strong, unique credentials for all ABB product instances.
Use product-specific configuration interface to update credentials
Network Segmentation
allIsolate ABB systems from untrusted networks and implement strict firewall rules to limit access.
Configure firewall to restrict access to ABB systems to authorized IPs only
🧯 If You Can't Patch
- Implement strict network segmentation to isolate ABB systems from untrusted networks.
- Enforce strong credential policies and regularly audit for default or weak passwords.
🔍 How to Verify
Check if Vulnerable:
Check if ABB ASPECT/NEXUS/MATRIX Series version 3.07 is installed and if default credentials from install packages are still in use.Check Version:
Check product documentation or system interface for version information; specific command varies by product.Verify Fix Applied:
Verify that credentials have been changed from defaults and attempt to authenticate with old default credentials (should fail).📡 Detection & Monitoring
Log Indicators:
- Failed login attempts with default usernames
- Successful logins from unexpected IP addresses
- Configuration changes from unauthorized users
Network Indicators:
- Unauthorized access attempts to ABB system ports
- Traffic patterns indicating credential guessing
