What is CVE-2024-42052?

A vulnerability exists in the MSI installer for Splashtop Streamer for Windows prior to version 3.5.8.0 due to the use of a temporary folder with insufficient permissions during the installation process. This configuration flaw allows a local user to exploit the weakness by placing a malicious 'wevtutil.exe' file into the temporary folder, enabling them to escalate their privileges to SYSTEM. As a result, this exposure could lead to unauthorized access and control over the affected systems, posing a significant risk to user data and system integrity.
