CVE-2025-12247Public exploit

LocalSystem code execution via unquoted service paths

Published Oct 27, 2025 · Updated Oct 27, 2025

Unquoted service paths in Hasleo Backup Suite 5.0 through 5.2 allow local users to execute code with LocalSystem privileges. The installer registers HasleoImageMountService and HasleoBackupSuiteService ImagePath values without quotes despite space-containing executable paths. A low-privileged user who can write an executable to an earlier path token and trigger a service start gains full control of the host.
