CVE-2024-5477

Estado: AplazadaAlta (7.3)—

A potential security vulnerability has been identified in the System BIOS for some HP PC products which may allow escalation of privilege, arbitrary code execution, denial of service, or information disclosure via a physical attack that requires specialized equipment and knowledge. HP is releasing firmware mitigation for the potential 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.

AV:P (acceso físico) y descripción de ataque con equipamiento especializado indican T1091. Vulnerabilidad en BIOS permite escalada de privilegios (T1068), ejecución de código arbitrario (T1059) e acceso a información (T1005).

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.
