CVE-2019-5218

Estado: ModificadaAlta (8.8)—

Se presenta una vulnerabilidad de autenticación insuficiente en Huawei Band 2 y Honor Band 3. La banda no autentica suficientemente el dispositivo que intenta conectar con ella en cierto escenario. Una explotación con éxito podría permitir al atacante suplantar y luego conectar con la banda.

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).
