CVE-2024-42052

SYSTEM privilege escalation via writable installer directory

Published Jul 28, 2024 · Updated Mar 20, 2025

Privilege escalation in Splashtop Streamer for Windows before 3.5.8.0 allows local users to execute code as SYSTEM during installation. During a forced MSI reinstall, the installer executes a missing wevtutil.exe from a user-writable folder under %TEMP% without securing that search location. A regular local account can reach the flaw only when the original MSI remains available or can be restored to its initial location, after which an attacker-controlled binary runs with SYSTEM privileges.
