SSA-595101: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.2.0.5

Publication Date:	2021-12-14
Last Update:	2021-12-14
Current Version:	V1.0
CVSS v3.1 Base Score:	7.8

SUMMARY

Siemens has released version V13.2.0.5 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read maliciously crafted files in different file formats (PDF, JT, TIFF, CGM and TIF). If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.

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

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/.
