CVE-2018-14815
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, Several out-of-bounds write vulnerabilities have 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 confidenceMultiple out-of-bounds write vulnerabilities in Fuji Electric V-Server versions 4.0.3.0 and prior allow remote attackers to execute arbitrary code by triggering the memory corruption through specially crafted network requests.

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 V-Server installationIdentify whether Fuji Electric V-Server software is installed on the target system by checking installed programs, program directories, or system inventoryAffected if Fuji Electric V-Server is found installed on the system
-
Determine installed V-Server versionLocate and retrieve the version information for the installed V-Server instance - typically found in program files, about dialogs, or system information utilitiesAffected if The installed version cannot be determined or is 4.0.3.0 or prior
-
Compare version against affected rangeCompare the identified version number to the affected range: all versions <= 4.0.3.0 are vulnerableAffected if The installed version is 4.0.3.0 or any prior version (e.g., 4.0.2.0, 4.0.1.0, etc.)
-
Assess network exposureDetermine if the V-Server service is running and accessible over the network - check if ports or services are listening on external interfacesAffected if The V-Server service is running and exposed to untrusted network segments
The system is affected if Fuji Electric V-Server is installed with version 4.0.3.0 or any earlier version, particularly if the service is 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 dataIsolate affected systems on restricted network segments, minimize exposure to untrusted networks, apply vendor patches when available, and implement compensating controls such as intrusion detection to monitor for exploitation attempts.
