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
An attacker could use a specially crafted URL to delete files outside the WebAccess/NMS's (versions prior to 3.0.2) control.

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

A path traversal vulnerability in WebAccess/NMS versions prior to 3.0.2 allows attackers to use specially crafted URLs to delete files outside the application's intended control directory, potentially leading to denial of service or further system compromise.

MitigationUpgrade WebAccess/NMS to version 3.0.2 or later to obtain the patch for this vulnerability.

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/NMS installation
    Locate the WebAccess/NMS installation directory or check for the web service process. Common locations include C:\WebAccess\ or /opt/webaccess/ on Linux systems. Look for nms.exe or related service processes.
    Affected if WebAccess/NMS software is found on the system
  2. Identify installed version
    Check the version of WebAccess/NMS. This is typically displayed in the web interface login page, in an about dialog, or in version files within the installation directory. Look for files like version.txt, about.html, or check the Windows service properties.
    Affected if The installed version cannot be determined or is displayed as a version prior to 3.0.2
  3. Compare version against affected range
    Review the identified version number against the affected range: versions prior to 3.0.2. If the version shown is 3.0.1, 2.x, or any version number less than 3.0.2, the installation is within the affected range.
    Affected if The installed version is any release prior to 3.0.2 (for example, 3.0.1, 3.0.0, 2.x, 1.x)
  4. Verify web interface accessibility
    Determine if the WebAccess/NMS web interface is exposed on the network. Check firewall rules, IIS/Apache configuration, or port bindings (typically ports 80, 443, or 8080). The vulnerability is exploitable through HTTP/HTTPS URLs.
    Affected if The web interface is accessible from network segments where untrusted users could submit crafted URLs

A system is affected if WebAccess/NMS is installed with any version prior to 3.0.2 and the web interface is network-accessible.

Upgrade available Upgrade to 3.0.2 or later
Fixed in 3.0.2
Interim mitigation

Upgrade WebAccess/NMS to version 3.0.2 or later to obtain the patch for this vulnerability.

Recommended fix High confidence

3.0.2

  1. Verify current WebAccess/NMS version by checking the application interface or system information
  2. Download WebAccess/NMS version 3.0.2 from the official Advantech vendor source
  3. Review upgrade documentation provided by Advantech for WebAccess/NMS
  4. Create a complete backup of the current WebAccess/NMS installation and configuration
  5. Stop the WebAccess/NMS service before initiating the upgrade
  6. Install version 3.0.2 following vendor-provided installation procedures
  7. Verify the upgrade was successful by checking the version number
  8. Restart the WebAccess/NMS service
Caveat Review vendor release notes for any configuration or compatibility changes in version 3.0.2 before upgrading
