Description

ntfs-3g mount helper in Ubuntu 16.04, 16.10, Debian 7, 8, and possibly 9 does not properly sanitize the environment when executing modprobe. This can be abused to load a kernel module and execute a binary payload as the root user.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
