CVE-2020-27000
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), Teamcenter Visualization (All versions < V13.1.0.1). Affected applications lack proper validation of user-supplied data when parsing BMP files. This can result in a memory corruption condition. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12018)
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 confidenceJT2Go and Teamcenter Visualization versions before V13.1.0.1 contain a memory corruption vulnerability due to improper validation of user-supplied data when parsing BMP files. An attacker can exploit this to execute arbitrary code within 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 if JT2Go or Teamcenter Visualization is installedCheck the system for installed Siemens visualization software. Look in Program Files for folders named 'Siemens\JT2Go' or 'Siemens\Teamcenter Visualization' or check Add/Remove Programs.Affected if Either JT2Go or Teamcenter Visualization software is present on the system
-
Determine the installed version of the softwareOpen the installed application and navigate to Help > About, or check the version information in the program's executable properties. The version is typically displayed as a numeric value like V13.0.x or V13.1.0.x.Affected if The installed version is a version number lower than 13.1.0.1 (for example, 13.0.0.5, 12.4.0.2, etc.)
-
Confirm the BMP file parsing capability is availableVerify that the software can open or import BMP image files, as this is the attack vector for the vulnerability. Try to import a BMP file or check file type associations in the application settings.Affected if The software can process BMP files and the version is below 13.1.0.1
A user is affected if they have JT2Go or Teamcenter Visualization installed with a version number lower than 13.1.0.1 and the software can open or process BMP files.
