A local regular user may modify the existing `C:\\ProgramData\\ComposerSetup\\bin\\composer.bat` in order to get elevated command execution when composer is run by an administrator. 2. A local regular user may create a specially crafted dll in the `C:\\ProgramData\\ComposerSetup\\bin` folder in order to get Local System privileges. See: https://itm4n.github.io/windows-server-netman-dll-hijacking. 3. If the directory of the php.exe selected by the user is not in the system path, it is added without checking that it is admin secured, as per Microsoft guidelines.
