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
Advantech/BroadWin WebAccess before 7.0 allows remote attackers to (1) enable date and time syncing or (2) disable date and time syncing via a crafted URL.

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

Unauthenticated URL manipulation vulnerability in Advantech/BroadWin WebAccess versions before 7.0 allows remote attackers to enable or disable date and time syncing functionality via crafted URLs without any authentication.

MitigationUpgrade to WebAccess version 7.0 or later. If immediate upgrade is not feasible, restrict network access to the WebAccess management interface using network segmentation or firewall rules to prevent unauthenticated external access.

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. Confirm WebAccess installation
    Check if Advantech WebAccess or BroadWin WebAccess software is installed on the system by looking for the installation directory (commonly C:\WebAccess or C:\BroadWeb) or check running services for WebAccess-related processes.
    Affected if The software is installed and running on the system.
  2. Identify installed version
    Locate the version information in the WebAccess installation, typically found in the about page of the web management interface, or in version files within the installation directory. Compare your version to the affected range: versions 5.0 and 6.0 (or any version <= 6.0) are vulnerable; version 7.0 and later are not.
    Affected if The installed version is 5.0, 6.0, or any version lower than 7.0.
  3. Verify web management interface accessibility
    Attempt to access the WebAccess web management interface from a browser. The default port is typically 80 or 8080. Try accessing common paths like / or /webaccess/ without providing any credentials.
    Affected if The web interface is accessible without authentication.
  4. Check time sync functionality exposure
    Inspect whether the date and time syncing functionality is exposed via URL parameters on the web interface. The vulnerability allows manipulation of time sync settings through crafted URLs without any login. Check for any exposed time sync controls or configuration pages.
    Affected if Time sync settings can be accessed or modified via the web interface without authentication.

The environment is affected if Advantech WebAccess version 5.0 or 6.0 (or any version <= 6.0) is installed, the web management interface is accessible, and the time syncing feature can be manipulated without authentication credentials.
