-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 # SSA-243317 File Parsing Vulnerability in Simcenter Femap and Parasolid Publication Date: 2022-07-12 Last Update: 2022-09-13 Current Version: 1.2 CVSS v3.1 Base Score: 7.8 SUMMARY ======= Simcenter Femap and Parasolid are affected by an out of bounds read vulnerability that could be triggered when the application reads files in NEU format. 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. AFFECTED PRODUCTS AND SOLUTION ============================== * Parasolid V33.1 - Affected versions: All versions < V33.1.264 - Remediation: Update to V33.1.264 or later version See further recommendations from section "Workarounds and Mitigations" - Download: https://support.sw.siemens.com/ * Parasolid V34.0 - Affected versions: All versions < V34.0.250 - Remediation: Update to V34.0.250 or later version See further recommendations from section "Workarounds and Mitigations" - Download: https://support.sw.siemens.com/ * Parasolid V34.1 - Affected versions: All versions < V34.1.233 - Remediation: Update to V34.1.233 or later version See further recommendations from section "Workarounds and Mitigations" - Download: https://support.sw.siemens.com/ * Simcenter Femap V2022.1 - Affected versions: All versions < V2022.1.3 - Remediation: Update to V2022.1.3 or later version See further recommendations from section "Workarounds and Mitigations" - Download: https://support.sw.siemens.com/ * Simcenter Femap V2022.2 - Affected versions: All versions < V2022.2.2 - Remediation: Update to V2022.2.2 or later version See further recommendations from section "Workarounds and Mitigations" - Download: https://support.sw.siemens.com/ WORKAROUNDS AND MITIGATIONS =========================== Siemens has identified the following specific workarounds and mitigations that customers can apply to reduce the risk: * Do not open untrusted NEU files in Simcenter Femap or Parasolid Product-specific remediations or mitigations can be found in the section "Affected Products and Solution". 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-2022-34465 The affected application contains an out of bounds read past the end of an allocated structure while parsing specially crafted NEU files. This could allow an attacker to execute code in the context of the current process.
