CVE-2017-1000086

Estado: ModificadaAlta (8)—

El plugin Period Backup no realiza ningún chequeo de permisos, lo que permite que cualquier usuario con acceso Overall/Read cambie su configuración, haga copias de seguridad, recupere o descargue copias de seguridad y también borre todas las copias de seguridad anteriores mediante la rotación de logs. Además, el plugin no necesita que se envíen peticiones a su API mediante POST, exponiéndose, en consecuencia, a ataques de tipo Cross-Site Request Forgery (CSRF).

CVSS

Probabilidad de explotación (EPSS)
