CVE-2014-0757
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 · uneditedSmart Software Solutions (3S) CoDeSys Runtime Toolkit before 2.4.7.44 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via unspecified vectors.
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.

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.
-
Locate CoDeSys Runtime Toolkit installationSearch the system for CoDeSys Runtime Toolkit components or related files. Common locations may include C:\Program Files\3S Software or C:\CoDeSys\, or check Program Files directories for any '3S' or 'CoDeSys' folders.Affected if CoDeSys Runtime Toolkit is found installed on the system
-
Identify installed CoDeSys Runtime Toolkit versionCheck the version of the installed CoDeSys Runtime Toolkit files or check the product version through the Windows Programs and Features control panel, or look for version information in the toolkit's DLL or executable file properties.Affected if The installed version is 2.4.7.43 or lower (versions prior to 2.4.7.44)
-
Verify runtime toolkit is in useConfirm that the CoDeSys Runtime Toolkit is actively deployed or running as part of a PLC, SCADA, or industrial control system application. Check for running processes or services related to CoDeSys.Affected if The runtime toolkit is deployed and actively running or configured to run
The environment is affected if CoDeSys Runtime Toolkit version 2.4.7.43 or lower is installed and actively deployed.

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 CoDeSys Runtime Toolkit to version 2.4.7.44 or later to remediate the vulnerability. If upgrading is not feasible, network segmentation and access controls may reduce attack surface.
