CVE-2013-1627
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 · uneditedAbsolute path traversal vulnerability in NTWebServer.exe in Indusoft Studio 7.0 and earlier and Advantech Studio 7.0 and earlier allows remote attackers to read arbitrary files via a full pathname in an argument to the sub_401A90 CreateFileW function.
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 confidenceAbsolute path traversal vulnerability in NTWebServer.exe allows remote attackers to read arbitrary files by passing full pathnames (e.g., C:\Windows\System32\config\sam) to the sub_401A90 CreateFileW function. The application fails to validate or restrict path inputs, enabling directory traversal beyond intended boundaries.

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 installed Indusoft Web Studio or Advantech Studio versionCheck the application version through Windows Programs and Features, or locate the installation directory (typically C:\Program Files\Indusoft or C:\Program Files\Advantech) and check version info of the main executableAffected if Installed version matches 6.1, 7.0, or 7.0b2 of Indusoft Web Studio or 6.1 of Advantech Studio
-
Locate NTWebServer.exe in the installation directorySearch for NTWebServer.exe in the installation folder, commonly found in the bin or root directory of the Studio installationAffected if NTWebServer.exe exists in the Indusoft/Advantech Studio installation folder
-
Check if NTWebServer service is runningOpen Windows Services (services.msc) and look for a service related to NTWebServer, or use command 'sc query' to enumerate running servicesAffected if NTWebServer.exe is running as a Windows service or process
-
Verify web server component is accessibleAttempt to access the NTWebServer HTTP port (default port 80 or configured port) on localhost using a browser or curl commandAffected if The web server interface is accessible and responds to HTTP requests
-
Test for path traversal vulnerabilitySend a crafted HTTP request to NTWebServer with a full Windows path such as 'GET /../../../../windows/win.ini' or 'GET /C:\Windows\win.ini' and observe if the file contents are returnedAffected if The server returns contents of files outside the web root directory, confirming the path traversal flaw exists
User is affected if they have Indusoft Web Studio 6.1/7.0/7.0b2 or Advantech Studio 6.1 installed with NTWebServer.exe running and accessible, and the path traversal test successfully reads arbitrary files.

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 dataUpdate to a patched version of Indusoft Studio/Advantech Studio if available; otherwise disable or restrict access to the NTWebServer.exe service and implement network segmentation to limit exposure.
