Ansible Playbook Error Message File Reader

Disclosed
N/A

Description

This module will read the first line of a file based on an error message from ansible-playbook with sudo privileges.
ansible-playbook takes a yaml file as input, and if there is an error, such as a non-yaml file, it outputs the line
where the error occurs. This can be exploited to read the first line of the file, which we'll typically want to read
/etc/shadow to obtain root's hash.
