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 "certificate_file_remove" 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 points. The 'certificate_file_remove' API accepts multiple parameters that are concatenated directly to OS-level commands without sanitization, allowing authenticated attackers to execute arbitrary OS commands.

MitigationApply vendor firmware updates to patch the command injection vulnerability. Until updates are available, restrict network access to the device management interface and disable unused services.

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. Confirm device model
    Access the device web interface or use SNMP/SSH to identify the exact model number (Eki 6333ac 2g, 2gd, or 1gpo). Check the device label, web UI header, or run 'cat /proc/cpuinfo' or 'uname -a' via debug shell if available.
    Affected if Device is an Advantech EKI-6333AC variant (2g, 2gd, or 1gpo)
  2. Identify installed firmware version
    In the web UI, navigate to Status or System > Firmware version. Alternatively, check the login page footer or system info page for the firmware build number.
    Affected if Firmware version is below 1.6.5 for 2g/2gd models, or below 1.2.2 for 1gpo model
  3. Verify certificate_file_remove API endpoint exists
    Review the device's API documentation or attempt a GET request to /cgi-bin/certificate_file_remove or similar paths. Check if the endpoint is listed in the web UI's API list or captured in network traffic during normal operation.
    Affected if The 'certificate_file_remove' API endpoint is present and accessible
  4. Check authentication configuration
    In the web UI, go to System > Administration or Security settings. Verify whether authentication is required for API access and whether default credentials are in use.
    Affected if The device allows authenticated access to the certificate_file_remove API

A user is affected if they have an Advantech EKI-6333AC (2g, 2gd, or 1gpo variant) running firmware below the patched versions (1.6.5 or 1.2.2 respectively) and the certificate_file_remove API is accessible with authentication.

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 to patch the command injection vulnerability. Until updates are available, restrict network access to the device management interface and disable unused services.

Recommended fix High confidence

EKI-6333AC-2G and EKI-6333AC-2GD: upgrade to firmware 1.6.5 or later; EKI-6333AC-1GPO: upgrade to firmware 1.2.2 or later

  1. 1. Identify the exact model of the Advantech EKI device (EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO)
  2. 2. Identify the current firmware version by accessing the device's web interface or using the device's CLI
  3. 3. Download the latest firmware from Advantech's official support website (www.advantech.com) or contact Advantech directly
  4. 4. Back up the current device configuration before upgrading
  5. 5. Access the device's web interface or management console
  6. 6. Navigate to the firmware upgrade section
  7. 7. Upload and apply the appropriate firmware: For EKI-6333AC-2G and EKI-6333AC-2GD, upgrade to version 1.6.5 or later; For EKI-6333AC-1GPO, upgrade to version 1.2.2 or later
  8. 8. Wait for the upgrade process to complete and the device to reboot
Caveat Standard firmware upgrade risks apply - ensure power stability during upgrade and backup configuration before proceeding
