Descriptions du CVE

Certain getText methods in the ActionSupport controller in Apache Roller before 5.0.2 allow remote attackers to execute arbitrary OGNL expressions via the first or second parameter, as demonstrated by the pageTitle parameter in the !getPageTitle sub-URL to roller-ui/login.rol, which uses a subclass of UIAction, aka "OGNL Injection."

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.
