DHCP Client Command Injection (DynoRoot)

Description

This module exploits the DynoRoot vulnerability, a flaw in how the NetworkManager integration script included in the DHCP client in Red Hat Enterprise Linux 6 and 7, Fedora 28, and earlier processes DHCP options. A malicious DHCP server, or an attacker on the local network able to spoof DHCP responses, could use this flaw to execute arbitrary commands with root privileges on systems using NetworkManager and configured to obtain network configuration using the DHCP protocol.

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.
