SUMMARY

Solid Edge is affected by multiple file parsing vulnerabilities that could be triggered when the application reads specially crafted files in various formats such as PAR or CFG format. This could allow an attacker to crash the application or execute arbitrary code.

Siemens has released a new version for Solid Edge SE2025 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-2025-40739

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