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 source of the vulnerability relies on multiple parameters belonging to the "applications_apply" API which are not properly sanitized before being concatenated to OS level commands.

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

OS command injection vulnerability in Advantech EKI-6333AC wireless access point devices. The 'applications_apply' API endpoint accepts multiple parameters that are directly concatenated to OS-level commands without proper input sanitization, allowing authenticated attackers to execute arbitrary OS commands.

MitigationApply vendor firmware updates when available; prior to patch availability, restrict network access to the device management interfaces and implement strict input validation at upstream network devices to block malicious API payloads.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 the device model
    Access the device web interface or check the device label to confirm it is an Advantech EKI-6333AC variant (2g, 2gd, or 1gpo)
    Affected if The device is an Advantech EKI-6333AC 2g, 2gd, or 1gpo model
  2. Check the installed firmware version
    Log into the device web interface and navigate to the Status or System Information page to view the firmware version, or use the command line and run 'cat /proc/version' or check the web UI footer for version information
    Affected if The firmware version is below 1.6.5 for 2g/2gd models, or below 1.2.2 for 1gpo model
  3. Verify if the applications_apply endpoint exists
    Check if the device web API exposes an endpoint at /cgi-bin/applications_apply or similar paths by reviewing the web application's URL structure or checking for related JavaScript files that reference this endpoint
    Affected if The applications_apply API endpoint is present and accessible
  4. Confirm authentication status
    Review whether the device requires authentication for API access and check if default credentials are in use or if an authenticated session can be established
    Affected if The device allows authenticated access to the applications_apply endpoint with valid credentials or exposes this endpoint without requiring authentication

The environment is affected if it runs an Advantech EKI-6333AC variant (2g/2gd < 1.6.5 or 1gpo < 1.2.2) with the applications_apply API endpoint accessible to authenticated users.

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; prior to patch availability, restrict network access to the device management interfaces and implement strict input validation at upstream network devices to block malicious API payloads.

Recommended fix High confidence

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

  1. 1. Identify the specific EKI model (EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO) from the affected device inventory
  2. 2. Access the device's firmware management interface or download the latest firmware from Advantech's official support portal
  3. 3. For EKI-6333AC-2G: Download firmware version 1.6.5 or later
  4. 4. For EKI-6333AC-2GD: Download firmware version 1.6.5 or later
  5. 5. For EKI-6333AC-1GPO: Download firmware version 1.2.2 or later
  6. 6. Upload the firmware to the device via the device's web interface or management console
  7. 7. Follow the device's firmware upgrade procedure carefully, ensuring stable power throughout the process
  8. 8. After upgrade, verify the device is operational and confirm the firmware version matches the target
Caveat Firmware upgrades on embedded devices may cause temporary service disruption; ensure upgrade is performed during maintenance window
