DLL Hijacking in Siemens Software Center and Solid Edge SE2025

IdentifiersCVE-2025-40827CWE-427· Uncontrolled Search Path Element

CVE-2025-40827 is a DLL hijacking vulnerability affecting Siemens Software Center before V3.5 and Solid Edge SE2025 before V225.0 Update 10. According to the provided content, the affected application insecurely loads a DLL such that an attacker can place a crafted malicious DLL on the system and have it loaded by the vulnerable software. Successful exploitation would result in arbitrary code execution in the security context of the affected application.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary code execution on the affected system. The attacker gains the ability to run attacker-controlled code in the context of the vulnerable Siemens application, which may enable compromise of the local host, installation of additional malware, data access available to that user context, and potential follow-on actions depending on the privileges of the process.

Mitigation

If you can’t patch tonight, do this now.

As a temporary mitigation, restrict the ability of untrusted users or processes to write DLL files into directories from which the affected applications may load libraries, including the application directory and other searched paths. Enforce least privilege, monitor for unexpected DLL files near the application, and use application control or allowlisting to prevent unauthorized DLL loading until patched versions can be deployed.

Remediation

Patch, then assume compromise.

Upgrade Siemens Software Center to V3.5 or later and Solid Edge SE2025 to V225.0 Update 10 or later. Applying the vendor-provided fixed versions is the primary remediation based on the provided information.
