-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 # SSA-518824 Multiple File Parsing Vulnerabilities in Simcenter Femap and Parasolid Publication Date: 2022-09-13 Last Update: 2022-09-13 Current Version: 1.0 CVSS v3.1 Base Score: 7.8 SUMMARY ======= Simcenter Femap and Parasolid are affected by multiple file parsing vulnerabilities that could be triggered when the application reads files in X_T file formats. If a user is tricked to open a malicious file with the affected applications, an attacker could leverage the vulnerability to perform remote code execution in the context of the current process. Siemens has released updates for the affected products and recommends to update to the latest versions.

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 =================== Parasolid is a 3D geometric modeling tool that supports various techniques, including solid modeling, direct editing, and free-form surface/sheet modeling. Simcenter Femap is an advanced simulation application for creating, editing, and inspecting finite element models of complex products or systems. 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-2022-39137 The affected application is vulnerable to out of bounds read past the end of an allocated buffer when parsing X_T files.
