CVE-2025-43715 (GCVE-0-2025-43715)

Vulnerability from cvelistv5 – Published: 2025-04-17 00:00 – Updated: 2025-04-17 19:16
VLAI
Summary
Nullsoft Scriptable Install System (NSIS) before 3.11 on Windows allows local users to escalate privileges to SYSTEM during an installation, because the temporary plugins directory is created under %WINDIR%\temp and unprivileged users can place a crafted executable file by winning a race condition. This occurs because EW_CREATEDIR does not always set the CreateRestrictedDirectory error flag.
