CVE-2020-1795

Estado: ModificadaBaja (2.4)—

There is a logic error vulnerability in several smartphones. The software does not properly restrict certain operation when the Digital Balance function is on. Successful exploit could allow the attacker to bypass the Digital Balance limit after a series of operations.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).
