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 "cfg_cmd_set_eth_conf" 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

Critical OS command injection vulnerability (CWE-78) in Advantech EKI-6333AC wireless access points. The unauthenticated 'edgserver' service fails to sanitize input in the 'cfg_cmd_set_eth_conf' operation, allowing remote attackers to execute arbitrary OS commands with root privileges.

MitigationIsolate affected devices behind firewalls to block external access to the edgserver service; contact Advantech for firmware updates to patch the vulnerability; disable edgserver if not required for operations.

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 EKI-6333AC model variant
    Access the device web interface or check the device label to determine if the unit is an EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO variant
    Affected if The device is any of these three variants and the firmware version is below the patched release
  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 u-boot environment if accessible
    Affected if The firmware version is below 1.6.5 for 2G/2GD models or below 1.2.2 for the 1GPO model
  3. Verify the edgserver service is running
    Access the device via SSH or serial console and run 'ps | grep edgserver' to check if the edgserver process is active
    Affected if The edgserver process is running on the device
  4. Check network exposure of the edgserver service
    Review firewall rules or network configuration to determine if the edgserver service port (typically port 8080 or as configured) is exposed to untrusted networks or the internet
    Affected if The edgserver service port is accessible from untrusted network segments or directly from the internet
  5. Confirm cfg_cmd_set_eth_conf operation is accessible
    Attempt to send a specially crafted request to the edgserver endpoint for cfg_cmd_set_eth_conf; in a safe test environment, verify the operation accepts unsanitized input by attempting benign command injection testing with controlled characters
    Affected if The cfg_cmd_set_eth_conf operation accepts and processes unsanitized input without validation

The device is affected if it is an EKI-6333AC variant (2G, 2GD, or 1GPO) running firmware below 1.6.5 (or 1.2.2 for 1GPO) and the edgserver service is exposed on the network.

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

Isolate affected devices behind firewalls to block external access to the edgserver service; contact Advantech for firmware updates to patch the vulnerability; disable edgserver if not required for operations.

Recommended fix Moderate confidence

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

  1. 1. Identify the exact model number 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 portal (support.advantech.com)
  3. 3. Access the device's web-based management interface or console
  4. 4. Navigate to the firmware upgrade section
  5. 5. Upload and apply firmware version 1.6.5 or later for EKI-6333AC-2G/EKI-6333AC-2GD models
  6. 6. Upload and apply firmware version 1.2.2 or later for EKI-6333AC-1GPO model
  7. 7. Verify the upgrade was successful by checking the firmware version in the device interface
  8. 8. Confirm the 'edgserver' service is now running the patched version
Caveat firmware upgrades on network devices may cause temporary connectivity interruption; ensure backup of configuration before upgrading
