CVE-2026-4145

Estado: AnalizadaAlta (8.5)—

During an internal security assessment, a potential vulnerability was discovered in Lenovo Software Fix that could allow a local authenticated user to perform arbitrary code execution with elevated privileges.

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:L, PR:L sin UI:R indica escalada local autenticada. Ejecución de código arbitrario con privilegios elevados: T1068 como explotación, T1059 (ejecución) y T1548 (elevación) como impactos.

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.
