CVE-2014-9202
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 · uneditedMultiple stack-based buffer overflows in an unspecified DLL file in Advantech WebAccess before 8.0_20150816 allow remote attackers to execute arbitrary code via a crafted file that triggers long string arguments to functions.
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 confidenceMultiple stack-based buffer overflow vulnerabilities exist in an unspecified DLL file within Advantech WebAccess versions prior to 8.0_20150816. The vulnerabilities are triggered when the application processes crafted files containing excessively long string arguments to specific functions, leading to potential arbitrary code execution by remote attackers.

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 Advantech WebAccess installation and versionCheck the Windows registry under HKLM\SOFTWARE\Advantech\WebAccess\Version or look in the installation directory (typically C:\Advantech\WebAccess\) for version information files. You can also check the file properties of the main executable (usually BEMSErver.exe or similar).Affected if The installed version is 8.0 but earlier than build 20150816 (8.0_20150816).
-
Confirm WebAccess services are runningOpen Windows Services (services.msc) and check for Advantech WebAccess services such as 'Advantech WebAccess Scada' or 'WebAccess Manager'. Alternatively, run 'tasklist | findstr -i webaccess' from an elevated command prompt.Affected if The vulnerable version (8.0 prior to 20150816) is installed AND the WebAccess service or application is actively running, making the attack surface accessible.
-
Identify the WebAccess installation directoryNavigate to the typical installation path (C:\Advantech\WebAccess\ or C:\Program Files\Advantech\WebAccess\) and list the contents. Look for subdirectories containing DLL files used by the application.Affected if The installation directory contains the vulnerable version and the core application files (especially the unspecified DLL with the buffer overflow) are present.
-
Check for project files that may process external inputLook in the WebAccess\project directory for .wmp or .iad project files. These files may contain configuration data that gets processed by the vulnerable DLL functions when the application handles crafted files.Affected if The application has project files that could be targets for crafted malicious files exploiting the buffer overflow vulnerability.
You are affected if Advantech WebAccess version 8.0 is installed with a build date earlier than 20150816 and the application service is actively running.

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 dataUpgrade Advantech WebAccess to version 8.0_20150816 or later to obtain the vendor patch. If immediate patching is not feasible, restrict network access to the affected systems and implement input validation controls for file processing.
