Description

This module exploits CVE-2018-17456, which affects Git
versions 2.14.5, 2.15.3, 2.16.5, 2.17.2, 2.18.1, and 2.19.1 and lower.

When a submodule url which starts with a dash e.g "-u./payload" is passed
as an argument to git clone, the file "payload" inside the repository
is executed.

This module creates a fake git repository which contains a submodule
containing the vulnerability. The vulnerability is triggered when the
submodules are initialised (e.g git clone --recurse-submodules URL)
