Name of the Vulnerable Software and Affected Versions Nullsoft Scriptable Install System (NSIS) versions prior to 3.11

Description The issue allows local users to escalate privileges to SYSTEM during an installation. This occurs because the temporary plugins directory is created under %WINDIR%temp and unprivileged users can place a crafted executable file by winning a race condition. The EW CREATEDIR does not always set the CreateRestrictedDirectory error flag.

Recommendations For versions prior to 3.11, update to version 3.11 or later to resolve the issue. As a temporary workaround, consider restricting access to the temporary plugins directory under %WINDIR%temp to minimize the risk of exploitation.
