CVE-2014-0987
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 · uneditedStack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the NodeName2 parameter.
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 confidenceStack-based buffer overflow vulnerability in Advantech WebAccess 7.2 web interface allows remote attackers to overflow a stack buffer by providing an overly long NodeName2 parameter, enabling 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.
-
Identify if Advantech WebAccess is installedCheck for the presence of Advantech WebAccess software on the system. Common installation paths include C:\Program Files\Advantech\WebAccess or C:\WebAccess. Look for the WebAccess application in Windows Add/Remove Programs.Affected if Advantech WebAccess is installed on the system
-
Determine the installed versionOpen the WebAccess configuration or about page, check the installation directory for version files, or use Windows Add/Remove Programs to view the installed version. Common version file locations: C:\WebAccess\version.txt or within the WebAccess SCADA folder.Affected if The installed version is exactly 7.2
-
Check if the web interface is accessibleAttempt to access the WebAccess web interface via HTTP/HTTPS on common ports such as 80, 8080, or 443. The typical URL format is http://hostname/AdvantechWebAccess or http://hostname:port/.Affected if The WebAccess 7.2 web interface is reachable over the network
-
Verify the NodeName2 parameter is acceptedSend a test HTTP POST or GET request to a WebAccess login or configuration page that accepts a NodeName2 parameter, with an excessively long string (e.g., 1000+ characters) to observe if input length validation is present.Affected if The NodeName2 parameter accepts excessively long input without validation
The environment is affected if Advantech WebAccess version 7.2 is installed and its web interface is accessible, as the stack-based buffer overflow can be triggered via the NodeName2 parameter.

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 dataApply vendor patch for Advantech WebAccess 7.2; if no patch available, restrict network access to the web interface and implement input length validation on the NodeName2 parameter.
