CVE-2021-34327
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 ASM 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-13423)
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 across JT2Go, Solid Edge SE2021, and Teamcenter Visualization. The DLL fails to validate user-supplied data when parsing ASM files, leading to an out-of-bounds write that can be exploited for 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 Siemens productsCheck the system for JT2Go, Solid Edge, or Teamcenter Visualization installations by reviewing installed programs in Control Panel or using: Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersionAffected if Any of these three products are installed and the version falls below 13.2.0 for JT2Go/Teamcenter Visualization, or is se2021 or earlier for Solid Edge
-
Locate the vulnerable DLLSearch for plmxmlAdapterSE70.dll in the application installation directories, typically under the program's bin or common files foldersAffected if The DLL exists in the JT2Go, Solid Edge, or Teamcenter Visualization installation directory, confirming the presence of the affected component
-
Determine exact product versionRight-click the application executable, select Properties, and check the File Version tab; or use the vendor's version detection method for the specific productAffected if The version is below 13.2.0 for JT2Go or Teamcenter Visualization, or is se2021 or any version labeled se2021 for Solid Edge
-
Confirm ASM file parsing capabilityAttempt to open or import an ASM file within the installed Siemens application to verify the parsing functionality is accessibleAffected if The application can parse ASM files, as the vulnerability is triggered during ASM file processing where plmxmlAdapterSE70.dll handles user-supplied data without validation
The environment is affected if any of the three products (JT2Go, Solid Edge SE2021, or Teamcenter Visualization) are installed with versions below the fixed releases, and the application can process ASM files using the vulnerable plmxmlAdapterSE70.dll component.
