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-798 "Use of Hard-coded Credentials" 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 is associated to the backup configuration functionality that by default encrypts the archives using a static password.

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 wireless access points (EKI-6333AC-2G, EKI-6333AC-2GD, EKI-6333AC-1GPO) contain hardcoded credentials in their backup configuration functionality. The backup archives are encrypted using a static password that is hardcoded into the firmware, allowing anyone who obtains this password to decrypt and extract sensitive configuration data.

MitigationChange the default encryption password in the backup configuration functionality immediately. If available, apply vendor firmware updates that remove the hardcoded credentials. Contact Advantech for patched firmware versions.

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 your exact device model
    Log into the device web interface or check the physical label to confirm the model is one of EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO
    Affected if The model is any of these three variants
  2. Check installed firmware version
    Access 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 'firmwareversion' if available
    Affected if Firmware version is below 1.6.5 for EKI-6333AC-2G or EKI-6333AC-2GD, or below 1.2.2 for EKI-6333AC-1GPO
  3. Locate backup configuration files
    Check for .cfg or .backup files on the device via the web interface (typically under Maintenance > Backup/Restore) or via FTP/TFTP if enabled
    Affected if Any backup configuration archives exist on the device or have been exported
  4. Inspect firmware for hardcoded password strings
    If you have access to the firmware image (download from vendor or extract from device), search for static strings related to backup encryption using binwalk, strings, or a hex editor
    Affected if A static encryption password is found embedded in the firmware binary

You are affected if you own an EKI-6333AC model and your firmware version falls below the thresholds (1.6.5 for 2G/2GD, 1.2.2 for 1GPO) and backup configuration files using the hardcoded password exist or the password is present in the firmware.

Generated from the published advisory. Verify against your own configuration.

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.

From vendor data
Upgrade available Upgrade to 1.2.2 / 1.6.5 or later
Fixed in 1.2.21.6.5
Interim mitigation

Change the default encryption password in the backup configuration functionality immediately. If available, apply vendor firmware updates that remove the hardcoded credentials. Contact Advantech for patched firmware versions.
