A malicious actor with access to the network and low privileges could exploit an Improper Input Validation vulnerability found in UniFi Protect Application to execute a Command Injection 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.

AV:N, PR:L, UI:N indica acceso remoto con privilegios mínimos sin interacción: T1210. Command Injection (CWE-20) permite T1059. CVSS S:C/I:H/A:H sugiere escalada a privilegios elevados (T1068).

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.
