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.

<?php /* source: https://www.securityfocus.com/bid/4026/info PHP's 'safe_mode' feature may be used to restrict access to certain areas of a filesystem by PHP scripts. However, a problem has been discovered that may allow an attacker to bypass these restrictions to gain unauthorized access to areas of the filesystem that are restricted when PHP 'safe_mode' is enabled. In particular, the MySQL client library that ships with PHP fails to properly honor 'safe_mode'. As a result, a user can issue a LOAD DATA statement to read files that reside in restricted areas of the filesystem (as determined by 'safe_mode'). */ /* PHP Safe Mode Problem This script will connect to a database server running locally or otherwise, create a temporary table with one column, use the LOAD DATA statement to read a (possibly binary) file, then reads it back to the client.
