Description
This module exploits the Shellshock vulnerability, a flaw in how the Bash shell
handles external environment variables. This module targets dhclient by responding
to DHCP requests with a malicious hostname, domainname, and URL which are then
passed to the configuration scripts as environment variables, resulting in code
execution.
