CVE-2020-28383
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 < V13.1.0.1), Solid Edge SE2020 (All Versions < SE2020MP12), Solid Edge SE2021 (All Versions < SE2021MP2), Teamcenter Visualization (All versions < V13.1.0.1). Affected applications lack proper validation of user-supplied data when parsing PAR files. This can result in an out of bounds write past the memory location that is a read only image address. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11885)
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 vulnerability in JT2Go, Solid Edge SE2020/SE2021, and Teamcenter Visualization allows out-of-bounds memory writes when parsing specially crafted PAR files due to insufficient validation of user-supplied data. This can lead to arbitrary 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.
-
Check JT2Go versionLocate the JT2Go installation and retrieve the version number (typically found in the application properties, about dialog, or executable metadata)Affected if Installed version is lower than 13.1.0.1
-
Check Solid Edge versionLocate the Solid Edge installation and retrieve the version number (typically found in the application properties, about dialog, or executable metadata)Affected if Installed version is se2020 or se2021 (any MP level)
-
Check Teamcenter Visualization versionLocate the Teamcenter Visualization installation and retrieve the version number (typically found in the application properties, about dialog, or executable metadata)Affected if Installed version is lower than 13.1.0.1
-
Identify PAR file usageDetermine whether the affected Siemens application is used to open or process PAR (Part) files, as this is the attack vector for the vulnerabilityAffected if The application processes PAR files and the version is within the affected ranges above
A user is affected if they have JT2Go or Teamcenter Visualization below version 13.1.0.1, or Solid Edge se2020/se2021 of any patch level, and they open or process malicious PAR files with these applications.

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 data13.1.0.1
Update affected applications to the specified minimum versions (JT2Go/Teamcenter Visualization: V13.1.0.1, Solid Edge SE2020: SE2020MP12, Solid Edge SE2021: SE2021MP2) or later to patch the vulnerability.
