CVE-2024-8036
📋 TL;DR
This vulnerability in ABB systems allows attackers to send specially crafted firmware or configuration files to system nodes, potentially causing denial of service (node stoppage/inaccessibility) or remote code execution. It affects ABB products running vulnerable firmware versions. Organizations using affected ABB industrial control systems are at risk.
💻 Affected Systems
- ABB system nodes (specific products not detailed in CVE)
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to take control of industrial control nodes, potentially disrupting critical operations or enabling further network penetration.
Likely Case
Denial of service causing affected nodes to become inaccessible or stop functioning, disrupting industrial processes.
If Mitigated
Limited impact with proper network segmentation and access controls preventing unauthorized firmware/configuration uploads.
🎯 Exploit Status
Requires ability to send specially crafted firmware/configuration files to target nodes. Likely requires some level of network access to the industrial control system.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://search.abb.com/library/Download.aspx?DocumentID=2NGA001911&LanguageCode=en&DocumentPartId=&Action=Launch
Restart Required: Yes
Instructions:
1. Review ABB advisory 2NGA001911. 2. Identify affected products and versions. 3. Apply vendor-provided firmware updates. 4. Restart affected systems. 5. Verify update success.
🔧 Temporary Workarounds
Network Segmentation
allIsolate industrial control systems from business networks and internet
Access Control
allRestrict who can send firmware/configuration updates to industrial nodes
🧯 If You Can't Patch
- Implement strict network segmentation to isolate industrial control systems
- Monitor for unauthorized firmware/configuration upload attempts and block suspicious sources
🔍 How to Verify
Check if Vulnerable:
Check system firmware version against vendor advisory and compare with vulnerable versions listCheck Version:
