  - Retrieve the Administrator password and sensitive configuration parameters like the pppoe
  username and password without authentication.

  - Execute privileged Commands without authentication through a race condition leading to weak
  authentication enforcement.

  - Sending formatted request to a victim which then will execute arbitrary commands on the device.

  - Store arbitrary javascript code which will be executed when a victim accesses the administrator
  interface.");
