This is a small tutorial write up that provides a DynoRoot exploit proof of concept.
05bd61cb8ce0024fe6348ca11ae1d9aa32b087a7faf6df353ddc2aface0c11ebThis Metasploit 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.
