CVE-2024-47876

Estado: AnalizadaAlta (8.7)—

Sakai is a Collaboration and Learning Environment. Starting in version 23.0 and prior to version 23.2, kernel users created with type roleview can log in as a normal user. This can result in illegal access being granted to the system. Version 23.3 fixes this vulnerability.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Red sin privilegios (AV:N, PR:N, UI:N) en aplicación expuesta; usuarios 'roleview' logran acceso de usuario normal, violando autenticación y autorización (CWE-285, CWE-863).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
