Full Report
Siemens Software Center and Solid Edge is affected by a DLL hijacking vulnerability. This could allow an attacker to execute arbitrary code via placing a crafted DLL file on the system. Siemens has released new versions for the affected products and recommends to update to the latest versions.
Analysis Summary
# Vulnerability: DLL Hijacking in Siemens Software Center and Solid Edge
## CVE Details
- **CVE ID:** CVE-2025-40827
- **CVSS Score:** 7.8 (High) - CVSS v3.1 / 8.5 (High) - CVSS v4.0
- **CWE:** CWE-427 (Uncontrolled Search Path Element)
## Affected Systems
- **Products:**
- Siemens Software Center
- Solid Edge SE2025
- **Versions:**
- Siemens Software Center: All versions prior to V3.5
- Solid Edge SE2025: All versions prior to V225.0 Update 10
- **Configurations:** Systems where an attacker has the ability to place files in directories searched by the application for DLL loading (typically the application directory or current working directory).
## Vulnerability Description
The affected applications contain a DLL hijacking vulnerability caused by an uncontrolled search path element. The software fails to properly validate or specify the full path of required dynamic link libraries (DLLs) before loading them. This allows an attacker to place a maliciously crafted DLL file in a location that the application searches prior to find the legitimate library, leading to the execution of the attacker's code within the context of the application.
## Exploitation
- **Status:** Not currently reported as exploited in the wild; PoC not public in advisory.
- **Complexity:** Low
- **Attack Vector:** Local (Requires the attacker to have the ability to place a file on the local file system; typically relies on user interaction to trigger).
## Impact
- **Confidentiality:** High (Full access to data handled by the application)
- **Integrity:** High (Ability to modify application data and system files)
- **Availability:** High (Potential for application or system crashes)
## Remediation
### Patches
- **Siemens Software Center:** Update to **V3.5** or a later version.
- **Solid Edge SE2025:** Update to **V225.0 Update 10** or a later version.
### Workarounds
- No specific software workarounds provided. Siemens recommends following general security practices:
- Protect network and local access to devices.
- Operate devices within protected IT environments.
- Follow Siemens' operational guidelines for Industrial Security.
## Detection
- **Indicators of Compromise:** Presence of unexpected or unsigned DLL files in application directories or user-writable folders from which the application is launched.
- **Detection Methods and Tools:**
- Use Endpoint Detection and Response (EDR) tools to monitor for unusual library loading behavior.
- Periodically audit file system integrity for unauthorized additions in automated software environments.
- Monitor for processes launching from unusual paths or with unexpected child processes.
