-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 # SSA-301589: Multiple File Parsing Vulnerabilities in Solid Edge, JT2Go and Teamcenter Visualization Publication Date: 2022-02-08 Last Update: 2022-06-14 Current Version: 1.3 CVSS v3.1 Base Score: 7.8 SUMMARY ======= Siemens has released updates for JT2Go, Solid Edge and Teamcenter Visualization to fix multiple file parsing vulnerabilities. If a user is tricked to open a malicious file (crafted as PDF, DXF or PAR) with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens has released updates for some of the affected products and recommends to update to the latest versions. Siemens is preparing further updates and recommends specific countermeasures for products where updates are not yet available.

Please follow the "General Security Recommendations". 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. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity 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. Solid Edge is a portfolio of software tools that addresses various product development processes: 3D design, simulation, manufacturing and design management. 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/. * Vulnerability CVE-2021-38405 The Datalogics APDFL library used in affected products is vulnerable to memory corruption condition while parsing specially crafted PDF files.
