ping `\`echo /etc/passwd\`` zsh: permission denied: /etc/passwd I may be wrong here, but would just returning \`rootyourmachine.sh\`` in the request body therefore work? Edit: Serving that from a web server via ping `curl localhost:9999` only causes ping to respond with a usage warning, as if you had entered an incorrect command. Is there a way to "break out of" ping from here, though?
