CVE-2021-34329
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 JT2Go (All versions < V13.2), Solid Edge SE2021 (All Versions < SE2021MP5), Teamcenter Visualization (All versions < V13.2). The plmxmlAdapterSE70.dll library in affected applications lacks proper validation of user-supplied data when parsing PAR files. This could result in an out of bounds write past the fixed-length heap-based buffer. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13427)
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 heap-based buffer overflow vulnerability exists in the plmxmlAdapterSE70.dll library used by JT2Go, Solid Edge SE2021, and Teamcenter Visualization. The library fails to properly validate user-supplied data when parsing PAR files, allowing an attacker to write beyond buffer boundaries and potentially execute arbitrary code 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 Siemens productsCheck for JT2Go, Solid Edge SE2021, or Teamcenter Visualization installations on the system. Look in common install directories such as C:\Program Files\Siemens or check Program Files/Program Files (x86) for Siemens folders.Affected if Any of these three products are installed
-
Check JT2Go versionIf JT2Go is installed, right-click the JT2Go application in the programs list and select Properties, or check the file version of JT2Go.exe in the installation directory. Compare the version number to 13.2.0.Affected if JT2Go version is below 13.2.0
-
Check Solid Edge versionIf Solid Edge is installed, check the version of the main executable (usually SolidEdge.exe) in the installation folder or view the program properties. Compare against se2021 and verify if MP5 patch has been applied.Affected if Solid Edge version is se2021 or earlier (before se2021MP5)
-
Check Teamcenter Visualization versionIf Teamcenter Visualization is installed, check the version of the visualization components or the main application executable. Compare to version 13.2.0.Affected if Teamcenter Visualization version is below 13.2.0
-
Verify vulnerable DLL existsSearch for plmxmlAdapterSE70.dll in the installation directories of the affected products. The DLL is the specific component with the overflow vulnerability.Affected if The plmxmlAdapterSE70.dll file exists in a Siemens product installation folder
-
Confirm PAR file parsing capabilityAttempt to open or load a PAR file in the installed product, or verify the product has the capability to import/parse PAR file formats.Affected if The product can parse PAR files, which is the attack vector for this vulnerability
A user is affected if they have JT2Go, Solid Edge SE2021, or Teamcenter Visualization installed with versions below the patched releases (13.2.0 for JT2Go/Teamcenter Visualization, se2021MP5 for Solid Edge) and the plmxmlAdapterSE70.dll component is present and capable of parsing 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 data13.2.0
Apply vendor patches by upgrading JT2Go and Teamcenter Visualization to version V13.2 or later, and Solid Edge SE2021 to SE2021MP5 or later. Until patches are applied, avoid opening untrusted PAR files from unknown sources.
