CVE-2021-22449

Estado: ModificadaAlta (7.5)—

Se presenta una vulnerabilidad lógica en Elf-G10HN versión 1.0.0.608. Un atacante no autenticado podría llevar a cabo operaciones específicas para explotar esta vulnerabilidad. Debido a un diseño de seguridad insuficiente, una explotación con éxito podría permitir a un atacante añadir usuarios para ser amigos sin preguntar en el dispositivo de destino.

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).
