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.
