CVE-2020-28381
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 SE2020 (All Versions < SE2020MP12), Solid Edge SE2021 (All Versions < SE2021MP2). Affected applications lack proper validation of user-supplied data when parsing PAR files. This could result in an out of bounds write into uninitialized memory. An attacker could leverage this vulnerability 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 confidenceA memory corruption vulnerability exists in Solid Edge CAD software where insufficient validation of user-supplied data during PAR file parsing leads to an out-of-bounds write into uninitialized memory, potentially allowing remote 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.
-
Confirm Solid Edge installationCheck for Solid Edge installation directory, typically under C:\Program Files\Siemens\SolidEdge or C:\Program Files (x86)\Siemens\SolidEdge. Also verify via Windows Add/Remove Programs list.Affected if Solid Edge software is present on the system
-
Identify installed Solid Edge versionLocate the main executable (solidedge.exe) in the installation folder and check its version properties via right-click Properties > Details, or run: powershell (Get-Item 'C:\Program Files\Siemens\SolidEdge\SolidEdge.exe').VersionInfoAffected if Version reported is se2020 or se2021 (any build), or any version prior to se2020
-
Verify PAR file handling capabilityPAR files are a native Solid Edge part file format. Confirm the installation includes the PAR file handler by checking for associated file associations or attempting to open any existing .par file in the software.Affected if Solid Edge can open or process PAR files, meaning the vulnerable parsing code is present in the installation
-
Determine patch level for se2020If version shows se2020, check if it is SE2020MP12 or later by reviewing the full version string in the executable properties.Affected if Version is se2020 and build is earlier than MP12
-
Determine patch level for se2021If version shows se2021, check if it is SE2021MP2 or later by reviewing the full version string in the executable properties.Affected if Version is se2021 and build is earlier than MP2
The environment is affected if Solid Edge se2020 (any build before MP12) or se2021 (any build before MP2) is installed and can process PAR files.

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: upgrade Solid Edge SE2020 to version SE2020MP12 or later, and SE2021 to version SE2021MP2 or later. Until patches are applied, avoid opening PAR files from untrusted sources.
