CVE-2023-24979
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 · uneditedA vulnerability has been identified in Tecnomatix Plant Simulation (All versions < V2201.0006). The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted SPP file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-19789)
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 · high confidenceTecnomatix Plant Simulation contains an out-of-bounds write vulnerability in its SPP file parsing routine. When parsing a specially crafted SPP file, the application writes past the end of an allocated buffer, leading to memory corruption that can be leveraged for arbitrary code execution in the context of the current process.

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 Tecnomatix Plant Simulation versionOpen the application and navigate to Help > About, or check the Windows Programs and Features list for the installed version numberAffected if The installed version is earlier than 2201.0006
-
Confirm SPP file handling capabilityVerify that the installation includes SPP file import functionality - check for .spp file association or import options in the File menuAffected if SPP file import is available and the version is below 2201.0006
-
Check for recent SPP file processing activityReview application logs or recently opened files in the application for .spp file usageAffected if SPP files have been opened with a vulnerable version
Environment is affected if Tecnomatix Plant Simulation version is below 2201.0006 and SPP files can be parsed

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.
dbcve · scoped2201.0006
Upgrade Tecnomatix Plant Simulation to version V2201.0006 or later to receive the vendor patch addressing this vulnerability.
V2201.0006 or later
- Obtain Tecnomatix Plant Simulation version V2201.0006 or later from official Siemens channels (e.g., Siemens Support Portal or cert-portal.siemens.com)
