CVE-2025-27577

Estado: AnalizadaAlta (7)—

in OpenHarmony v5.0.3 and prior versions allow a local attacker arbitrary code execution in tcb through race condition.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.10%
Percentil entre todas las CVEs puntuadas: 1
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation85 %

AV:L sin UI requiere acceso local; CWE-362 (race condition) facilita escalada de privilegios; "arbitrary code execution" en TCB confirma acceso a root/sistema, por tanto T1068 como impacto.

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.
