This module provides a PXE server, running a DHCP and TFTP server.
|
|
The default configuration loads a linux kernel and initrd into memory that
|
|
reads the hard drive; placing a payload to install metsvc, disable the
|
|
firewall, and add a new user metasploit on any Windows partition seen,
|
|
and add a uid 0 user with username and password metasploit to any linux
|
|
partition seen. The windows user will have the password p@SSw0rd!123456
|
|
(in case of complexity requirements) and will be added to the administrators
|
|
group.
|
|
|
|
See exploit/windows/misc/pxesploit for a version to deliver a specific payload.
|
|
|
|
Note: the displayed IP address of a target is the address this DHCP server
|
|
handed out, not the "normal" IP address the host uses.
