Go to dashboardSiemens Software Center before 4.0.9.8 loads DLLs from its own folder without checking them (CWE-427). Attackers in the Romulus ClickFix campaign are shipping a genuine signed SiemensSoftwareCenter.exe with malicious DLLs beside it, often in AppData\Local\Programs, so it works as a trusted loader. Siemens rates it CVSS v4 8.4 and v3.1 6.7. CISA added it to KEV on 2026-10-20, due 2026-11-03.

4.0.9.8 is affectedSM Software Provisioning Service in AppData\Local\Programs; activate.bak or statinfosta.DB next to the exe; an AppData\Local\FTSuite folder containing ftc.uml; unexpected DLLs beside Software Center executables outside the default install folder; connections to 96.62.218.59, wizardexpensive.com or 2.27.248.1274.0.9.8 or later; installs update automatically on next launchEach row is the first time that source carried this signal. The analyst’s rows are its own findings.
Siemens Software Center contains an uncontrolled search path element vulnerability that could allow an authenticated local attacker to place a specially crafted DLL in a directory that the application searches, leading to arbitrary code execution with the privileges of the affected application.
CISA required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable.
