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-79 "Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')" 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 remotely leveraging a rogue Wi-Fi access point with a malicious SSID.

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

This is a stored XSS vulnerability in Advantech EKI-6333AC wireless devices where the Wi-Fi SSID is not properly sanitized before display. An attacker can deploy a rogue access point with a malicious SSID containing XSS payloads; when the device scans for or displays available networks, the payload executes in the web interface.

MitigationApply vendor firmware updates to address the XSS vulnerability in SSID handling; until patches are available, disable Wi-Fi scanning features or use network segmentation to limit exposure to rogue access points.

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 device model and variant
    Locate the device label or access the web interface to confirm the exact model number (EKI-6333AC-2G, EKI-6333AC-2GD, or EKI-6333AC-1GPO)
    Affected if The device is not one of these three variants, the check does not apply
  2. Determine the installed firmware version
    Access the device web interface or check the firmware version via the admin console; compare the version number to the affected ranges (2G/2GD: < 1.6.5, 1GPO: < 1.2.2)
    Affected if The firmware version falls within the affected range for the specific model
  3. Verify Wi-Fi functionality is enabled
    Check the device wireless settings through the web interface or CLI to confirm Wi-Fi is active
    Affected if Wi-Fi is disabled, the vulnerability cannot be triggered through normal device scanning
  4. Inspect the available network list for suspicious SSIDs
    Access the wireless network scan results or client list in the web interface; examine any SSIDs for unusual characters such as <, >, script tags, or encoded payloads
    Affected if A stored XSS payload is present in any displayed SSID, indicating the device has processed a malicious beacon from a rogue access point

The device is affected if it is an EKI-6333AC variant with vulnerable firmware AND Wi-Fi scanning is enabled, particularly if anomalous SSIDs appear in the network list.

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 address the XSS vulnerability in SSID handling; until patches are available, disable Wi-Fi scanning features or use network segmentation to limit exposure to rogue access points.

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. Check the current firmware version installed on the device through the web interface or CLI
  3. 3. Download the firmware update from the official Advantech support website (www.advantech.com) or contact Advantech directly for the patched firmware
  4. 4. Backup the current device configuration before performing the upgrade
  5. 5. Upload and install firmware version 1.6.5 for EKI-6333AC-2G or EKI-6333AC-2GD, or version 1.2.2 for EKI-6333AC-1GPO
  6. 6. Verify the firmware upgrade was successful by checking the new version number
  7. 7. Restore the device configuration if a backup was made
  8. 8. After upgrade, validate that the device is functioning normally and the web interface is accessible
Caveat Review release notes for any configuration changes or feature modifications between versions; test in a non-production environment first
