CVE-2025-45095Public exploit

Local SYSTEM execution via unquoted service path

Published Oct 9, 2025 · Updated Oct 9, 2025

Unquoted service path in Lavasoft Web Companion 8.9.0.1091 through 12.1.3.1037 allows local users to execute code as SYSTEM. The DCIService Windows service registers its LocalSystem binary path without quotes, causing Windows to test attacker-placed executables in earlier path segments. Exploitation requires write access to an intermediate directory and a service restart or reboot, after which the substituted executable runs as LocalSystem.
