CVE-2024-48916

Estado: AplazadaAlta (8.1)—

Ceph is a distributed object, block, and file storage platform. In versions 19.2.3 and below, it is possible to send an JWT that has "none" as JWT alg. And by doing so the JWT signature is not checked. The vulnerability is most likely in the RadosGW OIDC provider. As of time of publication, a known patched version has yet to be published.

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.

JWT con algoritmo 'none' no verifica firma en RadosGW OIDC (AV:N, PR:L). Permite falsificar tokens de autenticación (T1078.004) y comprometer la identidad de usuarios. Afecta servicios remotos con acceso de red autenticado.

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.
