Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
AutomationDirect C-more EA9 HMI contains a function with bounds checks that can be skipped, which could result in an attacker abusing the function to cause a denial-of-service condition or achieving remote code execution on the affected device.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The AutomationDirect C-more EA9 HMI contains a vulnerability where bounds checks in a specific function can be bypassed, allowing an attacker to trigger a denial-of-service condition or achieve remote code execution on the affected device.

MitigationApply vendor-provided firmware updates when available; until then, isolate the HMI from untrusted networks and implement compensating controls such as network segmentation and access restrictions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm the device is a C-more EA9 HMI
    Log into the HMI or check the device documentation/model label to verify the exact model number is AutomationDirect C-more EA9 series
    Affected if The device is not an AutomationDirect C-more EA9 HMI model
  2. Identify the installed firmware version
    Access the HMI web interface, use the EA9 programming software, or check the device system information screen to retrieve the firmware version number
    Affected if The firmware version cannot be determined or is older than the vendor-patched version (compare against official AutomationDirect release notes)
  3. Assess network exposure of the HMI
    Review network firewall rules and VLAN configuration to determine if the HMI is directly accessible from untrusted networks or the internet
    Affected if The HMI has direct accessibility from external networks without firewall protection
  4. Check for unexpected service behavior or crashes
    Review system logs, event logs, or any available diagnostic information on the HMI for unexpected reboots, service failures, or error messages related to memory operations
    Affected if The HMI exhibits unexplained crashes, restarts, or error messages indicating memory corruption

You are affected if you have an AutomationDirect C-more EA9 HMI running firmware that predates the vendor fix, particularly if the device is network-accessible from untrusted segments.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
