CVE-2014-0766
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 · uneditedAn attacker can exploit this vulnerability by copying an overly long NodeName2 argument into a statically sized buffer on the stack to overflow the static stack buffer. An attacker may use this vulnerability to remotely execute arbitrary code.
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 confidenceThis is a stack-based buffer overflow vulnerability where an overly long NodeName2 argument is copied into a statically sized buffer on the stack, allowing an attacker to overwrite return addresses and execute arbitrary code remotely.

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.
-
Identify if Advantech Webaccess is installedSearch for the software in common installation directories such as C:\Program Files\Advantech\WebAccess or C:\Advantech\WebAccess, or check Windows Programs and Features for 'Advantech WebAccess'Affected if The software is not found in these locations or not listed in Programs and Features, indicating it is not installed
-
Determine the installed version of Advantech WebaccessLocate version information in the installation directory, typically in a file named version.txt, about.html, or in the executable properties (right-click on Dashboard.exe or common executables in the bin folder)Affected if The version is 5.0, 6.0, 7.0, or any version 7.1 or lower (7.1, 7.1.1, etc.)
-
Verify the NodeName2 parameter handling service is accessibleCheck if the WebAccess service (typically running on port 80/443 or configured HTTP port) is exposed and reachable on the network by attempting to access the web interfaceAffected if The web interface is accessible and accepts parameters, indicating the vulnerable code path could be reached
-
Inspect web access logs for NodeName2 parameter usageReview web server logs in the WebAccess\log directory for requests containing 'NodeName2' as a parameter, which would indicate the vulnerable function is being exercisedAffected if Log entries show NodeName2 parameter being passed to the application, confirming the affected code path is active
A user is affected if Advantech Webaccess versions 5.0, 6.0, 7.0, or any version 7.1 or lower is installed and the web interface handling the NodeName2 parameter is accessible.

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 dataImplement proper bounds checking on the NodeName2 parameter before copying, or replace unsafe string copy functions with safe alternatives (e.g., strncpy with length limits, snprintf) that enforce buffer size constraints.
