CVE-2026-47654

Estado: ModificadaAlta (7.5)—

Use after free in Remote Desktop Client allows an unauthorized attacker to execute code over a network.

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.

UI:R (interacción del usuario) en vector CVSS indica explotación cliente (T1203); CWE-416 (use-after-free) permite ejecución de código (T1059) en Windows RDP Client.

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.
