CVE-2024-28878
📋 TL;DR
The IO-1020 Micro ELD device downloads and executes code from adjacent network locations without proper verification, allowing attackers to run arbitrary code. This affects industrial control systems using this specific electronic logging device. Attackers can compromise the device and potentially connected systems.

⚠️ Risk & Real-World Impact
Worst Case
Complete device takeover leading to manipulation of logging data, disruption of operations, and lateral movement to other industrial systems.
Likely Case
Unauthorized code execution on the device allowing data manipulation, false reporting, or service disruption.
If Mitigated
Limited impact with proper network segmentation and monitoring, though device integrity remains compromised.
🎯 Exploit Status
Exploitation requires network access to adjacent location where malicious code can be placed. No authentication needed to trigger download/execution.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in advisory - contact vendor for latest patched version
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-24-093-01
Restart Required: Yes
Instructions:
1. Contact IOActive for latest firmware. 2. Backup device configuration. 3. Apply firmware update following vendor instructions. 4. Restart device. 5. Verify update applied successfully.
🔧 Temporary Workarounds
Network Segmentation
allIsolate IO-1020 devices on separate VLANs with strict firewall rules to prevent adjacent network access.
Access Control
allImplement strict network access controls to prevent unauthorized systems from being adjacent to IO-1020 devices.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate IO-1020 from other systems
- Monitor network traffic for unusual download attempts from adjacent locations
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against vendor's patched version list. If running any version prior to patched release, assume vulnerable.Check Version:
Check device web interface or console for firmware version (vendor-specific command)Verify Fix Applied:
Verify firmware version matches vendor's patched version and test that device no longer downloads/executes code from adjacent locations.📡 Detection & Monitoring
Log Indicators:
- Unexpected file downloads from network locations
- Unusual process execution
- Firmware modification attempts
Network Indicators:
- HTTP/FTP requests from device to adjacent network locations
- Unexpected outbound connections after download
SIEM Query:
