Add bind/reverse jjs unix cmd payloads.
The
jjs
tool is installed with JRE 8 and is installed on plenty of Linux desktop distros by default.I'm not sure how useful these payloads will be. Most Linux desktop distros will likely have a variety of other useful commands available (at least curl, wget, openssl, and probably perl and python) and probably whitelisted in application firewalls. Likewise, UNIX servers running JRE are likely to also have several viable tools available.
Also,
jjs
will apparently be deprecated and removed from JDK; however, it's unclear whetherjjs
will also be removed from JRE.The generated payloads are also not particularly
BadChar
friendly, as they contain' ) ; " |
and space characters. Most of these (with the exception of|
) could be removed by usingecho -e
and${IFS}
(nospace
encoder), at the expense of portability and introducing\ $ { }
as potentialBadChar
.It is also worth noting that the payload cmd process will continue to run if the session does not exit cleanly (ctrl+c), rather that cleanly terminating the shell process (
exit
), leaving a useless open socket.It's nice to have options. This will get you a shell.
