Local privilege escalation via unquoted service path
Published Jan 15, 2026 · Updated Jan 15, 2026
Unquoted service path in WiseCleaner Wise Care 365 5.6.7.568 allows local users to execute code with LocalSystem privileges. The WiseBootAssistant service registers its space-containing BootTime.exe path without quotation marks, causing Windows to search parent-path executable names first. Exploitation requires permission to place an executable in a searched location and execution occurs when the service or system restarts.
