Description

This module exploits a vulnerability in the handling of Windows Shortcut files (.LNK)
that contain a dynamic icon, loaded from a malicious DLL.

This vulnerability is a variant of MS15-020 (CVE-2015-0096). The created LNK file is
similar except an additional SpecialFolderDataBlock is included. The folder ID set
in this SpecialFolderDataBlock is set to the Control Panel. This is enough to bypass
the CPL whitelist. This bypass can be used to trick Windows into loading an arbitrary
DLL file.

If no PATH is specified, the module will use drive letters D through Z so the files
may be placed in the root path of a drive such as a shared VM folder or USB drive.
