SSA-518824: Multiple File Parsing Vulnerabilities in Simcenter Femap and Parasolid

Publication Date:	2022-09-13
Last Update:	2022-09-13
Current Version:	V1.0
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.

WORKAROUNDS AND MITIGATIONS

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

Do not open untrusted X_T files in Simcenter Femap or Parasolid

Product-specific 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.

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/.
