Descriptions du CVE

WordPress and WordPress MU before 2.8.1 exhibit different behavior for a failed login attempt depending on whether the user account exists, which allows remote attackers to enumerate valid usernames. NOTE: the vendor reportedly disputes the significance of this issue, indicating that the behavior exists for "user convenience."

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.
