CVE-2026-6348

Estado: AplazadaCrítica (9.3)—

WinMatrix agent developed by Simopro Technology has a Missing Authentication vulnerability, allowing authenticated local attackers to execute arbitrary code with SYSTEM privileges on the local machine as well as on all hosts within the environment where the agent is installed.

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 indica escalada local de privilegios (T1068). El atacante autenticado ejecuta código arbitrario con SYSTEM (T1059) y obtiene credenciales de administrador (T1078).

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.
