    CVE-2023-3181 (GCVE-0-2023-3181)

    Vulnerability from cvelistv5 – Published: 2024-01-25 15:22 – Updated: 2025-06-03 18:21
    VLAI
    Title
    Insecure Permissions in Splashtop Software Updater
    Summary
    The C:\Program Files (x86)\Splashtop\Splashtop Software Updater\uninst.exe process creates a folder at C:\Windows\Temp~nsu.tmp and copies itself to it as Au_.exe. The C:\Windows\Temp~nsu.tmp\Au_.exe file is automatically launched as SYSTEM when the system reboots or when a standard user runs an MSI repair using Splashtop Streamer’s Windows Installer. Since the C:\Windows\Temp~nsu.tmp folder inherits permissions from C:\Windows\Temp and Au_.exe is susceptible to DLL hijacking, standard users can write a malicious DLL to it and elevate their privileges.
