CVE-2024-48839
📋 TL;DR
This critical vulnerability in ABB ASPECT, NEXUS, and MATRIX series allows remote attackers to execute arbitrary code on affected systems by sending specially crafted input. It affects industrial control system software versions 3.08.02, potentially compromising operational technology environments.
💻 Affected Systems
- ABB ASPECT - Enterprise
- NEXUS Series
- MATRIX Series
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to take control of industrial control systems, disrupt operations, manipulate processes, and potentially cause physical damage or safety incidents.
Likely Case
Remote code execution leading to data theft, ransomware deployment, or lateral movement within industrial networks to compromise other systems.
If Mitigated
Limited impact if systems are air-gapped, have strict network segmentation, and input validation controls are implemented at network boundaries.
🎯 Exploit Status
CWE-94 (Improper Control of Generation of Code) with CVSS 10.0 suggests trivial exploitation; no authentication required based on description.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in reference; check vendor advisory for updated versions
Vendor Advisory: https://search.abb.com/library/Download.aspx?DocumentID=9AKK108469A7497&LanguageCode=en&DocumentPartId=&Action=Launch
Restart Required: Yes
Instructions:
1. Review ABB security advisory 9AKK108469A7497. 2. Apply vendor-provided patches or updates. 3. Restart affected systems. 4. Verify patch installation.
🔧 Temporary Workarounds
Network Segmentation
allIsolate affected systems from untrusted networks and implement strict firewall rules.
Input Validation Controls
allDeploy network-based input validation or web application firewalls to filter malicious input.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems from all untrusted networks
- Deploy intrusion detection/prevention systems with signatures for CVE-2024-48839 and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check software version in ABB ASPECT/NEXUS/MATRIX administration interface; if version is 3.08.02, system is vulnerable.Check Version:
Check through ABB software administration interface; no specific CLI command provided in advisory.Verify Fix Applied:
Verify software version has been updated to a patched version per vendor guidance; test with controlled input validation checks.📡 Detection & Monitoring
Log Indicators:
- Unusual process creation, unexpected network connections from ABB software, error logs showing input validation failures
Network Indicators:
- Unusual traffic patterns to/from ABB systems on non-standard ports, exploit-like payloads in network traffic
