CVE-2014-1697
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 · uneditedThe integrated web server in Siemens SIMATIC WinCC OA before 3.12 P002 January allows remote attackers to execute arbitrary code via crafted packets to TCP port 4999.
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 confidenceThe integrated web server in Siemens SIMATIC WinCC OA before version 3.12 P002 contains a vulnerability that allows remote attackers to execute arbitrary code by sending crafted packets to TCP port 4999. This likely indicates a buffer overflow or similar memory corruption issue in the web server component's packet handling routine.

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 the installed SIMATIC WinCC OA versionCheck the installed version through the Windows Add/Remove Programs list, or locate the installation directory and look for version information in the product documentation or about dialog within the application. Compare the version number to the affected range (anything <= 3.12).Affected if The installed version is 3.12 or earlier, or if the version cannot be determined but is known to be from before the P002 patch.
-
Determine if the integrated web server component is enabledCheck if the WinCC OA web server service is running. This can be done through Windows Services (services.msc) looking for a service related to WinCC OA web server, or by checking the web server configuration files in the WinCC OA installation directory.Affected if The web server component is enabled and running on the system.
-
Verify if TCP port 4999 is listeningUse the command 'netstat -an | findstr 4999' or a port scanning tool to check if TCP port 4999 is in a LISTENING state on the system. Also verify if the port is exposed to network access rather than bound to localhost only.Affected if TCP port 4999 is open and listening for incoming connections.
-
Check the installed patch level on version 3.12If the base version is 3.12, identify the specific patch level installed. This information is typically available in the application's About dialog, in the Windows installed programs details, or in the WinCC OA system information. Look specifically for P002 or later in the version string.Affected if The system is running version 3.12 without the P002 patch applied.
The environment is affected if SIMATIC WinCC OA version 3.12 or earlier is installed, the integrated web server is enabled, and TCP port 4999 is accessible, particularly without having applied the P002 patch.

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 SIMATIC WinCC OA version 3.12 P002 or later. Additionally, restrict network access to TCP port 4999 through firewalls or network segmentation to limit exposure to untrusted networks.
