CVE-2025-0960

9.8 CRITICAL

📋 TL;DR

AutomationDirect C-more EA9 HMI devices contain a buffer overflow vulnerability due to insufficient bounds checking. Attackers can exploit this to cause denial-of-service or execute arbitrary code remotely. Organizations using these industrial control system HMIs are affected.

💻 Affected Systems

Products:
  • AutomationDirect C-more EA9 HMI
Versions: Specific versions not detailed in provided references; consult vendor advisory for exact range.
Operating Systems: Embedded/Proprietary HMI OS
Default Config Vulnerable: ⚠️ Yes
Notes: Industrial control systems often run with default configurations in operational technology networks.

⚠️ 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).

🔒 Custom verification scripts are available for registered users. Sign up free to download automated test scripts.

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete device compromise, manipulation of industrial processes, or lateral movement into OT networks.

🟠

Likely Case

Denial-of-service causing HMI unavailability and disruption of monitoring/control functions in industrial environments.

🟢

If Mitigated

Limited impact with proper network segmentation and access controls preventing exploitation attempts.

🌐 Internet-Facing: HIGH - CVSS 9.8 indicates critical risk if exposed to internet, especially for unauthenticated exploitation.
🏢 Internal Only: HIGH - Even internally, these devices often lack proper segmentation and are critical to operations.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

CWE-120 (Buffer Copy without Checking Size of Input) typically leads to straightforward exploitation once details are known.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisory for specific patched versions

Vendor Advisory: https://community.automationdirect.com/s/cybersecurity/security-advisories

Restart Required: Yes

Instructions:

1. Review vendor advisory for affected versions. 2. Download and apply firmware update from AutomationDirect. 3. Restart HMI device. 4. Verify update applied successfully.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate HMI devices from untrusted networks using firewalls and VLANs

Access Control Lists

all

Restrict network access to HMI devices to only authorized IP addresses

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate HMI from business/IT networks
  • Deploy intrusion detection systems monitoring for buffer overflow attempts

🔍 How to Verify

Check if Vulnerable:

Check HMI firmware version against vendor advisory; vulnerable if running affected versions.

Check Version:

Check version through HMI interface: System Settings > About or similar menu

Verify Fix Applied:

Verify firmware version matches patched version specified in vendor advisory.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected device restarts
  • Memory access violations in system logs
  • Unusual network connections to HMI

Network Indicators:

  • Unusual traffic patterns to HMI ports
  • Buffer overflow attack signatures in network traffic

SIEM Query:

source="hmi_logs" AND (event_type="crash" OR event_type="memory_error") OR dest_ip="hmi_ip" AND protocol="tcp" AND payload_size>threshold
