'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'.
