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
A CWE-78 "Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')" was discovered affecting the following devices manufactured by Advantech: EKI-6333AC-2G (<= 1.6.3), EKI-6333AC-2GD (<= v1.6.3) and EKI-6333AC-1GPO (<= v1.2.1). The vulnerability can be exploited by remote unauthenticated users capable of interacting with the default "edgserver" service enabled on the access point and malicious commands are executed with root privileges. No authentication is enabled on the service and the source of the vulnerability resides in processing code associated to the "wlan_scan" operation.

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 · high confidence

A command injection vulnerability exists in the 'wlan_scan' operation of the 'edgserver' service on Advantech EKI-6333AC wireless access points. The service runs with root privileges and has no authentication, allowing remote unauthenticated attackers to inject arbitrary OS commands through unsanitized input in the wlan_scan function.

MitigationApply vendor firmware updates when available. If no update exists, disable the edgserver service if possible or implement network segmentation to restrict access to the device's management interface.

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. Identify device model
    Access the device's web interface or console and check the model number displayed in the system information or status page. Look for 'EKI-6333AC' variants including 2g, 2gd, or 1gpo.
    Affected if The device model is Advantech EKI-6333AC 2g, 2gd, or 1gpo.
  2. Check firmware version
    Navigate to the device's management interface (web UI or CLI) and locate the firmware version information, typically found under System, Status, or About sections. Compare the installed version against the affected ranges.
    Affected if The firmware version is below 1.6.5 for 2g/2gd models, or below 1.2.2 for 1gpo model.
  3. Verify edgserver service is running
    Access the device via SSH or console and run 'ps | grep edgserver' or check the service status to determine if the edgserver process is active.
    Affected if The edgserver service is running and exposed on the network.
  4. Confirm wlan_scan endpoint accessibility
    Attempt to access the wlan_scan functionality by sending a request to the edgserver service endpoint (typically via HTTP/HTTPS on the device's management interface). This may require checking exposed APIs or web endpoints.
    Affected if The wlan_scan operation is accessible without authentication and accepts user-supplied input.

A user is affected if they have an Advantech EKI-6333AC device (2g, 2gd, or 1gpo variant) running firmware below the fixed version with the edgserver service active and the wlan_scan endpoint exposed.

dbcve · scoped
Upgrade available Upgrade to 1.2.2 / 1.6.5 or later
Fixed in 1.2.21.6.5
Interim mitigation

Apply vendor firmware updates when available. If no update exists, disable the edgserver service if possible or implement network segmentation to restrict access to the device's management interface.

Recommended fix High confidence

EKI-6333AC-2G/2GD: firmware >= 1.6.5; EKI-6333AC-1GPO: firmware >= 1.2.2

  1. 1. Identify the exact model of the Advantech EKI device (EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO)
  2. 2. Download the firmware update from the official Advantech support website or contact Advantech directly for the patched firmware
  3. 3. For EKI-6333AC-2G and EKI-6333AC-2GD: Obtain firmware version 1.6.5 or later
  4. 4. For EKI-6333AC-1GPO: Obtain firmware version 1.2.2 or later
  5. 5. Review the device's firmware upgrade documentation for proper installation procedures
  6. 6. Upload and apply the firmware update via the device's management interface
  7. 7. After upgrade, verify the edgserver service is functioning correctly and the vulnerability is resolved
  8. 8. Confirm the device is running the patched firmware version
