CVE-2015-6457
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 · uneditedMoxa SoftCMS 1.3 and prior is susceptible to a buffer overflow condition that may crash or allow remote code execution. Moxa released SoftCMS version 1.4 on June 1, 2015, to address the vulnerability.
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 confidenceMoxa SoftCMS versions 1.3 and prior contain a buffer overflow vulnerability that could allow remote attackers to crash the application or execute arbitrary code. The vulnerability is exploitable over the network, as indicated by the high CVSS score, enabling unauthenticated remote code execution in successful attacks.

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 Moxa SoftCMS is installedCheck common installation directories for Moxa SoftCMS such as C:\Program Files\Moxa\SoftCMS or look for the SoftCMS service in Windows Services. On Linux, check /opt/moxa/softcms or similar paths.Affected if Moxa SoftCMS software is found on the system
-
Determine the installed versionLocate the SoftCMS executable or version file within the installation directory. Check for a version.txt, about dialog, or right-click the executable and view Properties > Details for version information.Affected if The installed version is 1.3 or any version lower than 1.3
-
Verify the SoftCMS service is runningOpen Services (services.msc) on Windows or run 'systemctl status softcms' or check process list on Linux to see if the SoftCMS service is actively running.Affected if The SoftCMS service is currently running
-
Check network exposureUse netstat or similar tools to determine if SoftCMS is listening on any network ports (common ports may include TCP 8080, 8000, or custom ports). Determine if the service is accessible from external network segments.Affected if SoftCMS is listening on accessible network ports and can be reached remotely
A system is affected if Moxa SoftCMS version 1.3 or prior is installed, the service is running, and the interface is exposed to the network, allowing unauthenticated remote attackers to exploit the buffer overflow.

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 Moxa SoftCMS to version 1.4 or later. If upgrading is not immediately feasible, network segmentation and restricting access to the SoftCMS service interface can reduce exposure.
