SSA-120378: Multiple File Parsing Vulnerabilities in Teamcenter Visualization and JT2Go

Publication Date:	2022-11-08
Last Update:	2023-06-13
Current Version:	V1.2
CVSS v3.1 Base Score:	7.8

SUMMARY

Siemens Teamcenter Visualization and JT2Go are affected by multiple file parsing vulnerabilities that could be triggered when the application reads malicious TIF, CGM or PDF files. If a user is tricked to open a malicious TIF, CGM or PDF file with 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.

WORKAROUNDS AND MITIGATIONS

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

Do not open untrusted CGM, TIF or PDF files in JT2Go and Teamcenter Visualization

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

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-2022-39136

The affected application is vulnerable to fixed-length heap-based buffer while parsing specially crafted TIF files. An attacker could leverage this vulnerability 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-122: Heap-based Buffer Overflow

Vulnerability CVE-2022-41660

The affected products contain an out of bounds write vulnerability when parsing a CGM file. An attacker can leverage this vulnerability 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-787: Out-of-bounds Write

Vulnerability CVE-2022-41661

The affected products contain an out of bounds read vulnerability when parsing a CGM file. An attacker can leverage this vulnerability 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-2022-41662

The affected products contain an out of bounds read vulnerability when parsing a CGM file. An attacker can leverage this vulnerability 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-2022-41663

The affected applications contain a use-after-free vulnerability that could be triggered while parsing specially crafted CGM files. An attacker could leverage this vulnerability 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-416: Use After Free

Vulnerability CVE-2022-41664
