CVE-2026-49203

Estado: AnalizadaAlta (7.2)—

Crucial management API endpoints for cellular eSIM allocation do not validate caller authorization, allowing remote profiles to be rewritten or deleted.

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.

AV:A (red adyacente) + API sin validación de autorización (CWE-287) permite acceso remoto a perfiles eSIM; impacto: suplantación (T1078) y manipulación de datos de configuración (T1565.001).

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.
