CVE-2025-10941

SYSTEM code execution via pre-created service directory

Published Sep 25, 2025 · Updated Sep 25, 2025

Local privilege escalation in Topaz SERVCore Teller 2.14.0-RC2 and 2.14.1 allows local users to execute code as SYSTEM. The installer creates the SERVCoreSmartClient service but neither checks nor resets ACLs on C:\ProgramData\SERVCoreTeller\Service, letting a pre-created directory remain user-controlled. A local unprivileged user must create the directory before administrative installation, replace nssm.exe afterward, and wait for a reboot to trigger SYSTEM execution.
