CVE-2022-50803

Estado: AplazadaCrítica (9.3)—

JM-DATA ONU JF511-TV version 1.0.67 uses default credentials that allow attackers to gain unauthorized access to the device with administrative privileges.

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 a red sin autenticación (AV:N/PR:N/UI:N) con credenciales por defecto permite acceso administrativo no autorizado al dispositivo. El impacto de confidencialidad, integridad y disponibilidad (VC:H/VI:H/VA:H) refuerza el compromiso total.

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.
