CVE-2026-50438

Estado: AnalizadaAlta (8.8)—

Improper link resolution before file access ('link following') in Microsoft PC Manager allows an authorized attacker to elevate privileges locally.

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.

CWE-59 (link following) + acceso local (AV:L) sin interacción (UI:N) + escalada de privilegios explícita en descripción → T1068. Impacto T1068 por elevación de privilegios a nivel del sistema (S:C con C:H/I:H/A:H).

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.
