# SSA-258115: DWG File Parsing Vulnerability in Solid Edge before SE2022MP9

Publication Date:        2022-10-11
Last Update:             2022-10-11
Current Version:         1.0
CVSS v3.1 Base Score:    7.8


SUMMARY
=======

Solid Edge is affected by a heap overflow vulnerability that could be
triggered when the application reads DWG files. If a user is tricked
to open a malicious file with the affected application, an attacker
could leverage the vulnerability to perform remote code execution in
the context of the current process.

Siemens has released an update for the Solid Edge and recommends to
update to the latest version.


AFFECTED PRODUCTS AND SOLUTION
==============================


* Solid Edge 
  - Affected versions:
       All Versions < SE2022MP9
  - Remediation:
       Update to SE2022MP9 or later version

       See further recommendations from section "Workarounds and Mitigations"
  - Download:
       https://support.sw.siemens.com/product/246738425/download


WORKAROUNDS AND MITIGATIONS
===========================

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

  * Do not open untrusted DWG 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-2022-37864

  The affected application contains an out of bounds write past the
  fixed-length heap-based buffer while parsing specially crafted DWG
  files. This could allow an attacker to execute code in the context
  of the current process. (ZDI-CAN-17627)

    CVSS v3.1 Base Score: 7.8
    CVSS Vector:          CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C
    CWE:                  CWE-122: Heap-based Buffer Overflow
