CVE-2023-0754
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 affected products are vulnerable to an integer overflow or wraparound, which could allow an attacker to crash the server and remotely execute arbitrary code.
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 confidenceInteger overflow/wraparound vulnerability allowing server crash and remote code execution. CVSS 9.8 indicates network-exploitable with no authentication required.

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 installed PTC Kepware productsCheck Windows Programs and Features or the installed services for 'Kepware', 'KEPServerEX', or review the product's About/Version dialog. For command-line, run: reg query 'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall' /s | findstr -i kepwareAffected if PTC Kepware Server, PTC Kepware ServerEx, or PTC Thingworx Kepware Edge is installed with version <= 6.12 (Server/ServerEx) or <= 1.5 (Thingworx Kepware Edge)
-
Identify GE Digital Industrial Gateway ServerCheck Windows Programs and Features or review services named 'Industrial Gateway Server' or similar. Check the installation directory for version information in the executable properties or release notes.Affected if GE Digital Industrial Gateway Server is installed with version <= 7.612
-
Identify PTC Thingworx SDKs and componentsReview installed development packages or applications containing 'Thingworx' in the name. For .NET SDK, check the GAC or installation folder for assembly version. For Edge C SDK, check the library binaries or accompanying version file.Affected if PTC Thingworx .NET SDK <= 5.8.4.971 or PTC Thingworx Edge C SDK <= 2.2.12.1052 is installed
-
Identify PTC Thingworx Edge MicroserverCheck for service or application named 'Thingworx Edge Microserver' or 'EMS'. Review the installation directory for version information in the executable or config files.Affected if PTC Thingworx Edge Microserver is installed with version <= 5.4.10.0
-
Identify PTC Thingworx Industrial ConnectivityCheck for any installed connectivity products with 'Thingworx Industrial Connectivity' in the name. Review the installation folder for version metadata.Affected if PTC Thingworx Industrial Connectivity of any version is installed (all versions affected)
If any of the listed PTC or GE Digital products are installed and the version falls within or below the specified vulnerable ranges, the environment is affected by CVE-2023-0754.

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 dataApply vendor-supplied patches immediately. If unavailable, implement strict input validation and bounds checking on integer operations; consider network segmentation and WAF rules as compensating controls.
