Publication Date:	2022-07-12
Last Update:	2022-09-13
Current Version:	V1.2
CVSS v3.1 Base Score:	7.8

SUMMARY

JT2Go and Teamcenter Visualization are affected by multiple file parsing vulnerabilities in Drawings SDK from Open Design Alliance. If a user is tricked to open a malicious DWG file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.

Siemens has released updates for the affected products and recommends to update to the latest versions.

Avoid to open untrusted files from unknown sources in JT2Go and Teamcenter Visualization

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

JT2Go is a 3D JT viewing tool to allow users to view JT, PDF, Solid Edge, PLM XML with available JT, VFZ, CGM, and TIF data.

Teamcenter Visualization software enables enterprises to enhance their product lifecycle management (PLM) environment with a comprehensive family of visualization solutions. The software enables enterprise users to access documents, 2D drawings and 3D models in a single environment.

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-2022-28807

Open Design Alliance Drawings SDK (all versions prior to 2023.2) is vulnerable to an out-of-bounds read when rendering DWG files after they are opened in the recovery mode. This could allow an attacker to execute code in the context of the current process.

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-125: Out-of-bounds Read

Vulnerability CVE-2022-28808

Open Design Alliance Drawings SDK (all versions prior to 2023.3) is vulnerable to an out-of-bounds read when reading DWG files in a recovery mode. This could allow an attacker to execute code in the context of the current process.

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-125: Out-of-bounds Read

Vulnerability CVE-2022-28809

Open Design Alliance Drawings SDK (all versions prior to 2023.3) is vulnerable to an out-of-bounds read when reading a DWG file with invalid vertex number in a recovery mode. This could allow an attacker to execute code in the context of the current process.

CVSS v3.1 Base Score	7.8
