SSA-856475: X_T File Parsing Vulnerabilities in Teamcenter Visualization and JT2Go

Publication Date:	2024-08-13
Last Update:	2024-08-13
Current Version:	V1.0
CVSS v3.1 Base Score:	7.8
CVSS v4.0 Base Score:	7.3

SUMMARY

Teamcenter Visualization and JT2Go are affected by out of bounds read and null pointer dereference vulnerabilities that could be triggered when the application reads files in X_T format. 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 new versions for the affected products and recommends to update to the latest versions.

VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2024-32635

The affected applications contain an out of bounds read past the unmapped memory region while parsing specially crafted X_T files. This could allow an attacker to execute code in the context of the current process.

CVSS v3.1 Base Score	7.8
CVSS v3.1 Vector	CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
CVSS v4.0 Base Score	7.3
CVSS v4.0 Vector	CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
CWE	CWE-125: Out-of-bounds Read

Vulnerability CVE-2024-32636

The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted X_T files. This could allow an attacker to execute code in the context of the current process.

CVSS v3.1 Base Score	7.8
CVSS v3.1 Vector	CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
CVSS v4.0 Base Score	7.3

CWE	CWE-125: Out-of-bounds Read

Vulnerability CVE-2024-32637

The affected applications contain a null pointer dereference vulnerability while parsing specially crafted X_T files. An attacker could leverage this vulnerability to crash the application causing denial of service condition.

CVSS v3.1 Base Score	3.3
CVSS v3.1 Vector	CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L
CVSS v4.0 Base Score	4.8
CVSS v4.0 Vector	CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N
CWE	CWE-476: NULL Pointer Dereference
