Cleaner Wrasse

Overview

  • Cleaner Wrasse is a tool that remotely enables the hidden busybox shell in routers using RouterOS versions 3.x - 6.43.14. CW doesn't care about the router's architecture or any periphials. It should just work. Once enabled, the hidden shell allows the devel user to login with the admin's password over telnet or SSH. The user is then presented with a root shell. It's damn useful.
