CVE-2022-27653
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 Simcenter Femap (All versions < V2022.2). The affected application contains an out of bounds write past the end of an allocated structure while parsing specially crafted .NEU files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-15594)
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 confidenceSimcenter Femap versions prior to V2022.2 contain an out-of-bounds write vulnerability when parsing specially crafted .NEU files. The application's parser writes past the end of an allocated structure, allowing an attacker to potentially achieve 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 Femap versionLocate the femap.exe executable (typically in C:\Program Files\Siemens\Femap or similar). Right-click the executable, select Properties, and check the File Version or Product Version field. Alternatively, open Windows Settings > Apps and Features, find Simcenter Femap, and note the installed version.Affected if The version displayed is earlier than 2022.2
-
Confirm .NEU file parsing capabilityOpen Femap and attempt to access the file import functionality. Go to File > Open or File > Import and verify that .NEU (Neutral) files are listed as a supported format or can be selected.Affected if The application can open or import .NEU files (this is a default capability in vulnerable versions)
-
Inspect recent .NEU file activityCheck the application's recent files list or default working directories for evidence of .NEU file processing. Look in the application log files or recent documents folder for .NEU file access.Affected if Recent .NEU files have been opened or imported by the application
If the installed version is earlier than 2022.2 and the application has processed .NEU files, the environment is likely affected by this vulnerability.

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 · scoped2022.2
Upgrade Simcenter Femap to version V2022.2 or later. Until patched, avoid opening .NEU files from untrusted or unknown sources.
Simcenter Femap V2022.2
- Check the current installed version of Simcenter Femap by opening the application and navigating to Help > About Simcenter Femap
