CVE-2025-11577

Estado: AplazadaAlta (7.6)—

Clevo’s UEFI firmware update packages, including B10717.exe, inadvertently contained private signing keys used for Boot Guard and Boot Policy Manifest verification. The exposure of these keys could allow attackers to sign malicious firmware that appears trusted by affected systems, undermining the integrity of the early boot process.

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.

Firmware UEFI contenía claves privadas en paquete B10717.exe (medio extraíble/software); permite firmar malware de boot que aparenta ser legítimo, comprometiendo integridad del arranque temprano.

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.
