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-15 "External Control of System or Configuration Setting" 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 authenticated users by restoring a tampered configuration backup.

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

Advantech EKI-6333AC wireless access point devices (models 2G, 2GD, and 1GPO) suffer from a CWE-15 vulnerability where authenticated users can restore a tampered configuration backup, allowing external control of system or configuration settings. The restore function lacks proper validation of configuration integrity, enabling manipulation of device settings through crafted backup files.

MitigationUpdate to vendor-patched firmware versions when available. Until then, restrict administrative access to trusted personnel only and avoid restoring configuration backups from untrusted sources.

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 EKI-6333AC model variant
    Log into the device web interface or check the device label to determine if the model is 1GPO, 2GD, or 2G
    Affected if The model is 1GPO, 2GD, or 2G and the firmware version falls below the fixed version for that model
  2. Check the installed firmware version
    Access the device administrative interface and navigate to Status or System Information to view the current firmware version. Alternatively, use the command line and run 'cat /proc/version' or check the web interface firmware upgrade page.
    Affected if The firmware version is below 1.2.2 for 1GPO model, or below 1.6.5 for 2GD or 2G models
  3. Verify if the configuration restore function exists
    Navigate to the device administrative interface and locate the Configuration Backup/Restore or Settings Restore functionality. This is typically found under System, Maintenance, or Administration menus.
    Affected if The device has a configuration restore or backup restore feature that accepts uploaded configuration files
  4. Test if the restore function accepts modified backup files
    If you have administrative access, attempt to restore a deliberately modified configuration backup file (in a safe, isolated test environment first). Observe if the device accepts and applies the modified configuration without integrity validation errors.
    Affected if The device accepts and applies a tampered configuration backup without validating its integrity, indicating the vulnerability is present

The device is affected if it is an Advantech EKI-6333AC model (1GPO, 2GD, or 2G) running firmware below the respective fixed versions (1.2.2 for 1GPO, 1.6.5 for 2GD/2G) AND the configuration restore feature accepts tampered backup files without integrity validation.

dbcve · scoped
Upgrade available Upgrade to 1.2.2 / 1.6.5 or later
Fixed in 1.2.21.6.5
Interim mitigation

Update to vendor-patched firmware versions when available. Until then, restrict administrative access to trusted personnel only and avoid restoring configuration backups from untrusted sources.

Recommended fix Moderate confidence

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

  1. 1. Identify the exact model number of the Advantech EKI-6333AC device (1GPO, 2G, or 2GD).
  2. 2. Determine the current firmware version by accessing the device's web interface or using the CLI.
  3. 3. Download the appropriate firmware version from the official Advantech support website: for EKI-6333AC-1GPO use version 1.2.2 or later; for EKI-6333AC-2G and EKI-6333AC-2GD use version 1.6.5 or later.
  4. 4. Back up the current device configuration before performing the firmware upgrade.
  5. 5. Upload and install the new firmware through the device's web interface or CLI following Advantech's standard firmware update procedure.
  6. 6. After upgrade, verify the firmware version has been successfully updated.
  7. 7. Restore the configuration backup and ensure the device operates normally.
