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 "snmp_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 · moderate confidence

OS command injection vulnerability in Advantech EKI-6333AC wireless access point series. The 'snmp_apply' API does not properly sanitize multiple parameters before concatenating them into OS-level commands, allowing authenticated attackers to execute arbitrary commands on the underlying operating system.

MitigationApply vendor-supplied firmware updates to versions beyond 1.6.3 (for EKI-6333AC-2G/2GD) and 1.2.1 (for EKI-6333AC-1GPO). If updates are unavailable, restrict network access to the device's management interface to trusted sources only.

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 label to confirm the exact model: EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO
    Affected if Device is any of these three models
  2. Check firmware version
    Navigate to the device web interface System Status or Firmware Upgrade page, or use SNMP or CLI to retrieve the firmware version. Compare against thresholds: 1.6.5 for 2G/2GD models, 1.2.2 for 1GPO model
    Affected if Firmware version is below 1.6.5 for 2G/2GD, or below 1.2.2 for 1GPO
  3. Verify SNMP service status
    Check if SNMP is enabled on the device through the web interface under SNMP Settings or by querying SNMP (snmpwalk) the device
    Affected if SNMP is enabled and accessible to the attacker
  4. Confirm management interface accessibility
    Determine if the device web management interface (HTTP/HTTPS) is reachable from untrusted networks by reviewing firewall rules or network ACLs
    Affected if Management interface is exposed to untrusted networks without IP restrictions

Device is affected if it is an EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO with firmware below the respective threshold and SNMP is enabled and reachable.

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.

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-supplied firmware updates to versions beyond 1.6.3 (for EKI-6333AC-2G/2GD) and 1.2.1 (for EKI-6333AC-1GPO). If updates are unavailable, restrict network access to the device's management interface to trusted sources only.

Recommended fix High confidence

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

  1. 1. Identify the specific model (EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO) of the affected Advantech device
  2. 2. Check the current firmware version via the device web interface or CLI
  3. 3. Download the firmware update from the official Advantech support portal (www.advantech.com) - ensure version 1.6.5 or later for EKI-6333AC-2G/2GD, or version 1.2.2 or later for EKI-6333AC-1GPO
  4. 4. Back up the current device configuration before upgrading
  5. 5. Upload the firmware file through the device's web management interface or via TFTP/FTP as documented in the device manual
  6. 6. Wait for the upgrade to complete and the device to reboot
  7. 7. Verify the new firmware version is installed and the SNMP service is functioning properly
  8. 8. Confirm the vulnerability is remediated by checking that SNMP parameters are now properly sanitized
Caveat Firmware upgrades may temporarily interrupt network connectivity; verify backup of configuration before proceeding
