• During an audit the Mikrotik RouterOS sshd (ROSSSH) has been identified to have a remote previous to authentication heap corruption in its sshd component.
  
  Exploitation of this vulnerability will allow full access to the router device.
  
  This analysis describes the bug and includes a way to get developer access to recent versions of Mikrotik RouterOS
  using the /etc/devel-login file. This is done by forging a modified NPK file using a correct signature and logging
  into the device with username ‘devel’ and the password of the administrator. This will drop into a busybox shell for
  further researching the sshd vulnerability using gdb and strace tools that have been compiled for the Mikrotik busybox
  platform.
  
  Shodanhq.com shows >290.000 entries for the ROSSSH search term.
