CVE-2014-0763
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 using SQL injection may use arguments to construct queries without proper sanitization. The DBVisitor.dll is exposed through SOAP interfaces, and the exposed functions are vulnerable to SOAP injection. This may allow unexpected SQL action and access to records in the table of the software database or execution of 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 · moderate confidenceThe DBVisitor.dll library exposes functions through SOAP interfaces that are vulnerable to SQL injection due to improper input sanitization. Attackers can exploit this by injecting malicious SQL arguments through SOAP requests, potentially allowing unauthorized database record access and arbitrary code execution.

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.
-
Verify Advantech Webaccess installationCheck for Advantech Webaccess in Windows installed programs via Control Panel > Programs and Features, or check for the installation directory typically at C:\Program Files\Advantech\WebAccess or C:\Advantech\WebAccessAffected if Advantech Webaccess is installed and the version falls within 5.0, 6.0, 7.0, or <=7.1
-
Confirm installed versionLocate the WebAccess installation directory and look for version information in version.txt, README, or check file properties of main executables like BroadWeb.exe or nodeMgr.exeAffected if The version displayed is 5.0, 6.0, 7.0, or any version up to and including 7.1
-
Identify vulnerable componentNavigate to the WebAccess installation directory and search for DBVisitor.dll file. Common paths include node\bin\DBVisitor.dll or SCADA\WebAccess\node\bin\DBVisitor.dllAffected if DBVisitor.dll exists in the installation directory, indicating the vulnerable library is present
-
Check SOAP service exposureReview IIS or embedded web server configuration for WebAccess. Check if the SOAP interface endpoints (typically under /WebAccess/SOAP or /WADriver/ paths) are enabled and accessibleAffected if The SOAP interface handlers in IIS or the embedded web server are enabled and publicly or internally accessible
-
Review SOAP request logsInspect web server logs (IIS logs or WebAccess logs) in the installation logs folder for suspicious SQL-like patterns in SOAP request parametersAffected if Log entries show SQL injection attempts or anomalous SQL syntax in SOAP request parameters
A defender is affected if Advantech Webaccess versions 5.0, 6.0, 7.0, or up to 7.1 is installed with DBVisitor.dll present and the SOAP interface enabled.

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 parameterized queries or prepared statements for all database operations in the SOAP interface handlers, and apply proper input validation and escaping for user-supplied data before constructing SQL queries.
