CVE-2014-0764
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 · uneditedBy providing an overly long string to the NodeName parameter, an attacker may be able to overflow the static stack buffer. The attacker may then execute code on the target device remotely.
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 confidenceA stack-based buffer overflow vulnerability exists in the NodeName parameter of the affected software/device. By sending an overly long string to this parameter, an attacker can overflow a static stack buffer and achieve remote code execution on the target system.

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 is installedLook for Advantech WebAccess installation directories (typically in C:\Program Files\Advantech\WebAccess or C:\Advantech\WebAccess) or check Windows Programs and Features for 'Advantech WebAccess' entryAffected if The software is not installed - no vulnerability present
-
Determine the installed versionCheck the version number in the Windows Programs and Features list, or look for version info in the installation directory (often in an About or Version file, or in the file properties of main executables like bd她去.exe or common.dll)Affected if The installed version is 5.0, 6.0, 7.0, or 7.1 or earlier (any version listed as <= 7.1)
-
Identify if the web service is runningCheck if the Advantech WebAccess web service is active by looking for IIS worker processes (w3wp.exe) hosting the WebAccess application, or by attempting to access the web interface on typical ports (80, 443, 8080)Affected if The web service is running and accessible on the network - the NodeName parameter is exposed
-
Verify NodeName parameter is reachableAccess the WebAccess dashboard or node configuration pages through the web browser and locate input fields for 'NodeName' or node configuration where user-supplied strings can be submitted to the serverAffected if The NodeName parameter input field exists and accepts user input - the vulnerable code path is present
The system is affected if Advantech WebAccess versions 5.0, 6.0, 7.0, or 7.1 (or any version <= 7.1) is installed with the web interface running and the NodeName parameter 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 strict input length validation and bounds checking on the NodeName parameter to ensure user-supplied data does not exceed the allocated buffer size. Additionally, consider using safer string handling functions and enabling compiler-level stack protection mechanisms.
