CVE-2023-49128
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 Solid Edge SE2023 (All versions < V223.0 Update 10). The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted PAR file. This could allow an attacker to execute code in the context of the current process.
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 confidenceSolid Edge SE2023 contains an out-of-bounds write vulnerability when parsing specially crafted PAR files. The vulnerability allows writing past the end of an allocated memory buffer, which can lead to arbitrary code execution in the context of the current process. This is a memory corruption vulnerability exploitable through malicious PAR files.

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.
-
Verify Solid Edge SE2023 is installedCheck for Solid Edge SE2023 in the installed programs list (Control Panel > Programs and Features) or search for 'Solid Edge' in the Start menuAffected if Solid Edge SE2023 appears in installed programs
-
Find the installed version numberOpen Solid Edge SE2023, then go to Help > About Solid Edge, or right-click the Solid Edge shortcut and select Properties to view version informationAffected if The displayed version is 223.0 or lower (versions < 223.0 or = 223.0 are affected)
-
Compare version against affected rangeNote the full version number (for example, 222.0, 222.1, 223.0) and compare it to the affected range: any version less than 223.0, or exactly version 223.0Affected if Version is 223.0 or any version below 223.0 (such as 222.0, 222.1, etc.)
-
Assess PAR file usage exposureDetermine if the system or workflow involves opening PAR (parameter) files from external or untrusted sources, as this is the attack vector for this vulnerabilityAffected if Users routinely open PAR files from unknown or untrusted origins
A system is affected if Solid Edge SE2023 version 223.0 or any earlier version (such as 222.x) is installed and users open PAR files, since the vulnerability triggers during PAR file parsing.

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 · scoped223.0
Update Solid Edge SE2023 to version V223.0 Update 10 or later. Avoid opening PAR files from untrusted sources.
V223.0 Update 10
- Identify current Solid Edge SE2023 version via Help > About Solid Edge
- Download Solid Edge SE2023 V223.0 Update 10 or later from Siemens support portal
- Close all Solid Edge instances
- Run the installer and follow prompts to upgrade
- Verify the installed version shows V223.0 Update 10 or higher after upgrade
