CVE-2026-54406

Estado: AnalizadaAlta (8.7)—

A malicious actor with access to the network and high privileges could exploit a Path Traversal vulnerability found in self-hosted instances of UniFi Network Application to escalate write permission on the host device.

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.

Acceso de red con privilegios altos (PR:H) en aplicación remota de auto-alojamiento permite path traversal (CWE-22) para escalada de permisos de escritura en el host. T1210 por red+PR:H; impactos: manipulación de ficheros (CWE-22) + escalada a privilegios de administrador.

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.
