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 "basic_htm" 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 (models 2G, 2GD, and 1GPO). The 'basic_htm' API endpoint contains multiple parameters that are not sanitized before being concatenated to OS-level commands, allowing authenticated attackers to execute arbitrary commands on the underlying operating system.

MitigationApply vendor-released firmware updates that address this vulnerability; until patches are available, restrict network access to the device management interfaces and monitor for indicators of compromise.

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 web interface or check the physical device label to confirm it is an Advantech EKI-6333AC variant (2G, 2GD, or 1GPO).
    Affected if The device is an EKI-6333AC 2G, 2GD, or 1GPO model.
  2. Check installed firmware version
    Log into the device web interface and navigate to the Status or System Information page to view the firmware version. Alternatively, access the device via SSH or console and run 'cat /proc/version' or check the firmware version in the system settings.
    Affected if The firmware version is less than 1.6.5 (for 2G/2GD models) or less than 1.2.2 (for 1GPO model).
  3. Verify web management interface is enabled
    Confirm the device web management interface (HTTP/HTTPS) is accessible and the 'basic_htm' API endpoint responds. Check the device network configuration to see if the web interface is enabled.
    Affected if The web management interface is accessible and the basic_htm endpoint is available.
  4. Confirm authentication is in use
    Verify that authentication is required to access the device management interface. Check if default credentials are in use or if admin accounts are configured with passwords.
    Affected if The device management interface is accessible without proper authentication or uses default credentials, allowing an attacker to reach the vulnerable endpoint.

If the device is an EKI-6333AC variant with firmware below 1.6.5 (2G/2GD) or below 1.2.2 (1GPO) and the web management interface is accessible, the device is affected by this command injection vulnerability.

Interim mitigation

Apply vendor-released firmware updates that address this vulnerability; until patches are available, restrict network access to the device management interfaces and monitor for indicators of compromise.

Recommended fix High confidence

Firmware 1.6.5 for EKI-6333AC-2G and EKI-6333AC-2GD; Firmware 1.2.2 for EKI-6333AC-1GPO

  1. Identify the exact model number of the Advantech EKI device (EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO)
  2. Access the device's web management interface or administrative console
  3. Navigate to the Firmware Upgrade or System Settings section
  4. Obtain the firmware update from the official Advantech support website (www.advantech.com) ensuring it matches your specific model
  5. Upload and apply firmware version 1.6.5 for EKI-6333AC-2G or EKI-6333AC-2GD models
  6. Upload and apply firmware version 1.2.2 for EKI-6333AC-1GPO model
  7. Verify the firmware upgrade was successful by checking the firmware version in the device status
  8. Restart the device if prompted to complete the update
Caveat Ensure backup of configuration before upgrade; some legacy settings may not persist between major version changes
