'Name' => “HP StorageWorks P4000 Virtual SAN Appliance Login Buffer Overflow”,
‘Description’ => %q{
This module exploits a buffer overflow vulnerability found in HP’s StorageWorks
P4000 VSA on versions prior to 10.0. The vulnerability is due to an insecure usage
of the sscanf() function when parsing login requests. This module has been tested
successfully on the HP VSA 9 Virtual Appliance.
