CVE-2026-22557

Estado: AplazadaCrítica (10)—

A malicious actor with access to the network could exploit a Path Traversal vulnerability found in the UniFi Network Application to access files on the underlying system that could be manipulated to access an underlying account.

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.

Vector CVSS con AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). CWE-22 (Path Traversal) permite leer archivos del sistema (T1005); el texto menciona acceso a cuentas subyacentes (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.
