CVE-2026-110936
Medium 6.7 Exploited
In plain English
A medium-severity uncontrolled search path in Siemens Software Center from Siemens. Attackers are actively exploiting it in the wild (listed by CISA on October 20, 2026). The chance it is exploited in the next 30 days is estimated at 1.0% (higher than 62% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code. 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. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

Official description
A vulnerability has been identified in Siemens Software Center (All versions < V4.0.9.8). The affected application loads dynamic-link libraries (DLLs) from an uncontrolled search path. This 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.
