CVE-2020-1794

Estado: ModificadaMedia (4.6)—

There is an improper authentication vulnerability in several smartphones. The applock does not perform a sufficient authentication in certain scenarios, successful exploit could allow the attacker to gain certain data of the application which is locked. Affected product versions include:HUAWEI Mate 20 versions Versions earlier than 10.0.0.188(C00E74R3P8);HUAWEI Mate 30 Pro versions Versions earlier than 10.0.0.203(C00E202R7P2).

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).
