CVE-2020-27006
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 of PCT files. This could result in a memory corruption condition. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12182)
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 confidenceMemory corruption vulnerability in Siemens JT2Go and Teamcenter Visualization applications caused by insufficient validation of user-supplied data during PCT file parsing. The lack of bounds checking allows attackers to trigger memory corruption, potentially achieving arbitrary code execution within the context of the running 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 visualization productCheck for presence of JT2Go or Teamcenter Visualization installation directories under Program Files/Siemens, or look for corresponding executables (JT2Go.exe, TeamcenterVisualization.exe)Affected if Either JT2Go or Teamcenter Visualization is installed on the system
-
Determine JT2Go versionRight-click on JT2Go.exe in the installation folder, select Properties, then view the Details tab for the Product Version fieldAffected if The version shown is lower than 13.1.0.1 (e.g., 13.0.x, 12.x.x, etc.)
-
Determine Teamcenter Visualization versionRight-click on the Teamcenter Visualization executable in its installation folder, select Properties, then view the Details tab for the Product Version fieldAffected if The version shown is lower than 13.1.0.1 (e.g., 13.0.x, 12.x.x, etc.)
-
Confirm PCT file handling capabilityThe vulnerability is triggered when parsing PCT files - this is a built-in file format capability of these products; no specific configuration needs to be enabled for the flaw to applyAffected if The product can open or process PCT files (default behavior for these visualization tools)
If either JT2Go or Teamcenter Visualization is installed with a version lower than 13.1.0.1, the environment is affected by this CVE.

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
Upgrade to JT2Go and Teamcenter Visualization version V13.1.0.1 or later. Until patched, avoid opening PCT files from untrusted sources.
