CVE-2025-55231

Estado: AnalizadaAlta (7.5)—

Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Storage allows an unauthorized attacker to execute code over a network.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.50%
Percentil entre todas las CVEs puntuadas: 40
Fecha de la puntuación: 5/10/2026

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.

ExplotaciónT1203 Exploitation for Client Executionexecution75 %
Impacto principalT1059 Command and Scripting Interpreterexecution70 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation65 %

Vector CVSS UI:R (interacción del usuario) indica explotación en el cliente (T1203). La race condition en Storage permite ejecución de código (T1059) y potencial escalada de privilegios (T1068) tras interacción del usuario.

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.
