CVE-2025-67653
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 · uneditedAdvantech WebAccess/SCADA is vulnerable to directory traversal, which may allow an attacker to determine the existence of arbitrary files.
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 confidenceAdvantech WebAccess/SCADA contains a directory traversal vulnerability that allows remote attackers to determine the existence of arbitrary files on the underlying system via specially crafted HTTP requests. This information disclosure flaw could aid attackers in mapping system paths and identifying sensitive files for further exploitation.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Advantech WebAccess/SCADA is installedCheck for WebAccess/SCADA installation directories (commonly C:\Advantech\WebAccess or C:\Inetpub\WebAccess) or look for IIS web applications named 'WebAccess'Affected if The software is not present on the system
-
Identify installed versionCheck version info in the installation folder, typically in about.html, version.txt, or the README file within the WebAccess installation directoryAffected if Installed version equals 9.2.1 exactly (this specific version is affected)
-
Verify web service is runningCheck if the Advantech WebAccess web service is running - look for IIS worker process (w3wp.exe) hosting the WebAccess application or check if port 80/443 (or configured HTTP ports) are listeningAffected if Web service is not running (no attack surface)
-
Check web interface accessibilityAttempt to access the WebAccess login page via browser or curl: http://<server>/WADemo or the default WebAccess root pathAffected if Web interface is externally accessible from untrusted networks
Your environment is affected only if Advantech WebAccess/SCADA version 9.2.1 is installed AND the web interface is accessible (even internally), since the directory traversal vulnerability can be exploited via HTTP requests to disclose file existence.

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 dataApply vendor patches when available; implement strict input validation and path sanitization on file access parameters in web interface code; restrict web server file system permissions to minimize accessible directories.
