CVE-2018-14823
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 · uneditedFuji Electric V-Server 4.0.3.0 and prior, A stack-based buffer overflow vulnerability has been identified, which may allow remote code execution.
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 confidenceA stack-based buffer overflow vulnerability in Fuji Electric V-Server versions 4.0.3.0 and prior may allow remote attackers to execute arbitrary code by exploiting the memory corruption flaw.

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 V-Server installationCheck the system for installed Fuji Electric V-Server software. On Windows, check Add/Remove Programs or the installation directory for a program named V-Server. On Linux, check /opt or common application installation paths.Affected if V-Server software is installed on the system
-
Determine installed V-Server versionLocate the V-Server application and retrieve its version information. Common methods include: right-clicking the executable and selecting Properties > Details, using the program's About dialog, or checking any version file in the installation directory.Affected if The installed version is 4.0.3.0 or any version prior to 4.0.3.0
-
Verify V-Server service statusCheck if the V-Server service or daemon is currently running. On Windows, open Services and look for V-Server. On Linux, run 'ps aux' or check systemd for the V-Server process.Affected if The V-Server service is running and exposed to network access
-
Confirm network exposureReview firewall rules and network configuration to determine if the V-Server service ports are accessible from network sources. Check for open ports typically used by V-Server or review any port bindings in V-Server configuration files.Affected if V-Server is listening on accessible network ports
The environment is affected if Fuji Electric V-Server version 4.0.3.0 or prior is installed and the service is running and network-accessible.

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 dataGiven the critical CVSS score (9.8) and potential for remote code execution, immediate vendor consultation for patches and network segmentation is recommended until a vendor-supplied fix can be applied.
