SSA-997779: File Parsing Vulnerability in Solid Edge before V2023 MP1

Publication Date:	2023-01-10
Last Update:	2023-01-10
Current Version:	V1.0
CVSS v3.1 Base Score:	7.8

SUMMARY

Solid Edge is affected by memory corruption vulnerability that could be triggered when the application read files in different file formats such as PAR, ASM, DFT. 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 an update for Solid Edge and recommends to update to the latest version.

AFFECTED PRODUCTS AND SOLUTION

Affected Product and Versions	Remediation
Solid Edge All versions < V2023 MP1	Update to V2023 MP1 or later version See further recommendations from section Workarounds and Mitigations

WORKAROUNDS AND MITIGATIONS

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

Do not open untrusted files in Solid Edge

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.

PRODUCT DESCRIPTION

Solid Edge is a portfolio of software tools that addresses various product development processes: 3D design, simulation, manufacturing and design management.

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-2022-47967

The DOCMGMT.DLL contains a memory corruption vulnerability that could be triggered while parsing files in different file formats such as PAR, ASM, DFT. This could allow an attacker to execute code in the context of the current process.
