CVE-2018-6402

Estado: ModificadaAlta (7.5)—

Ecobee Ecobee4 4.2.0.171 devices can be forced to deauthenticate and connect to an unencrypted Wi-Fi network with the same SSID, even if the device settings specify use of encryption such as WPA2, as long as the competing network has a stronger signal. An attacker must be able to set up a nearby SSID, similar to an "Evil Twin" attack.

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).
