# SSA-483182: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter
Visualization before V13.2

Publication Date:        2021-07-13
Last Update:             2021-07-13
Current Version:         1.0
CVSS v3.1 Base Score:    7.8

SUMMARY
=======

Siemens has released version V13.2 for JT2Go and Teamcenter
Visualization to fix multiple vulnerabilities that could be triggered
when the products read files in different file formats (GIF, TIFF, BMP,
J2K, JT, SGI, PDF, PCT, PCX, PAR and ASM ). If a user is tricked to
opening of a malicious file with the affected products, this could lead
to application crash, or potentially arbitrary code execution on the
target host system.

Siemens recommends to update to the latest versions and to limit opening
of untrusted files from unknown sources in the affected products.

WORKAROUNDS AND MITIGATIONS
===========================

Siemens has identified the following specific workarounds and mitigations that
customers can apply to reduce the risk:

* Avoid to open untrusted files from unknown sources in JT2Go and
Teamcenter Visualization



GENERAL SECURITY RECOMMENDATIONS
================================

As a general security measure, Siemens strongly recommends to protect
network access to devices with appropriate mechanisms. In order to
operate the devices in a protected IT environment, Siemens recommends to
configure the environment according to Siemens' operational guidelines
for Industrial Security (Download:
https://www.siemens.com/cert/operational-guidelines-industrial-security),
and to follow the recommendations in the product manuals.

PRODUCT DESCRIPTION
===================

JT2Go is a 3D JT viewing tool to allow users to view JT, PDF, Solid
Edge, PLM XML with available JT, VFZ, CGM, and TIF data.

Teamcenter Visualization software enables enterprises to enhance their
product lifecycle management (PLM) environment with a comprehensive
family of visualization solutions. The software enables enterprise users
to access documents, 2D drawings and 3D models in a single environment.

VULNERABILITY CLASSIFICATION
============================

The vulnerability classification has been performed by using the CVSS scoring
system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS
environmental score is specific to the customer's environment and will impact
the overall CVSS score. The environmental score should therefore be
individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a
community-developed list of common software security weaknesses. This serves as
a common language and as a baseline for weakness identification, mitigation,
and prevention efforts. A detailed list of CWE classes can be found at:
https://cwe.mitre.org/.
