Estado: AplazadaAlta (7)—

grub2 allowed attackers with access to the grub shell to access files on the encrypted disks.

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:P (acceso físico) → T1091 (medios extraíbles). Atacante con acceso físico al shell de GRUB accede a archivos en discos cifrados, logrando lectura de datos (T1005) y potencial extracción de credenciales/secretos (T1552).

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.
