  ## Remote command execution
  After we logged in to the victims router – using the hard coded accounts, we can trigger the second vulnerability and achieve remote command execution.
  
  User controlled input is not sufficiently filtered, allowing user to inject arbitrary commands into ping test arguments in Diagnostics page.
  
  By entering the following input in the ping test arguments in Diagnostics page, the attacker can get the /etc/passwd file:
  
  ```
