CWE ID 379


CVE-2023-3181 is a vulnerability that affects the C:\Program Files (x86)\Splashtop\Splashtop Software Updater\uninst.exe process. It creates a folder at C:\Windows\Temp~nsu.tmp and copies itself to it as Au_.exe. When the system reboots or when a standard user runs an MSI repair using Splashtop Streamer's Windows Installer, the C:\Windows\Temp~nsu.tmp\Au_.exe file is automatically launched as SYSTEM. This poses a risk as the C:\Windows\Temp~nsu.tmp folder inherits permissions from C:\Windows\Temp, making it susceptible to DLL hijacking. Standard users can write a malicious DLL to this folder and potentially elevate their privileges. The vulnerability has a high severity rating and can have significant impact on confidentiality, integrity, and availability of affected systems.
