Re: 18 ways to escalate privileges in Zone Labs ZoneAlarm Security Suite build 6.1.744.000
Dear Reed Arvin,
Having insecure directory in PATH is configuration bug, because PATH
is expected way to search required dynamic libraries under Windows.
In your very case, user can elevate privileges by simply overwriting
binaries of Active Perl installation.
In case Active Perl doesn't let you to place binary files in Program
Files, you may report it as Active Perl vulnerability, otherwise, it's
vulnerability of yourself. It's common practice to set security on any
directory you create in disk root folder.
