SUMMARY

Siemens Solid Edge is affected by multiple file parsing vulnerabilities that could be triggered when the application reads malicious PAR or ASM files. If a user is tricked to open a malicious file with the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.

Siemens has released a new version for Solid Edge SE2024 and recommends to update to the latest version.

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-2024-54093

The affected application is vulnerable to heap-based buffer overflow while parsing specially crafted ASM 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
