This module exploits unauthenticated simple web backdoor shells by leveraging the
|
|
common backdoor shell's CMD parameter to execute commands. The SecLists project of
|

Daniel Miessler and Jason Haddix has a lot of samples for these kind of backdoor shells
|
|
which is categorized under Payloads.
