CVE-2015-3947
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 · uneditedSQL injection vulnerability in Advantech WebAccess before 8.1 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.
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 confidenceSQL injection vulnerability in Advantech WebAccess versions prior to 8.1 allows remote authenticated users to execute arbitrary SQL commands through unspecified input vectors. The vulnerability stems from improper input validation in database queries, enabling attackers to manipulate SQL statements.

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 installationLocate the WebAccess installation directory and verify the application files exist. Common paths include C:\Advantech\WebAccess or directories under the IIS web root.Affected if Advantech WebAccess is installed on the system
-
Determine installed WebAccess versionAccess the WebAccess About page through the web interface, or check version metadata in the main DLL files or version.ini file located in the installation directory.Affected if The installed version is 8.0 or earlier (versions prior to 8.1)
-
Verify web interface network exposureDetermine if the WebAccess web portal (typically on port 80/443) is reachable from network locations or if remote authenticated access is permitted.Affected if The web interface is exposed to remote or untrusted network users
A system is affected if Advantech WebAccess version 8.0 or earlier is installed and its web interface accepts remote authenticated connections.

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 to Advantech WebAccess version 8.1 or later to obtain the vendor patch. As an interim measure, restrict network access to the WebAccess interface to trusted users only, and implement web application firewall rules to detect and block SQL injection attempts.
