CVE-2020-1802

Estado: ModificadaMedia (4.6)—

There is an insufficient integrity validation vulnerability in several products. The device does not sufficiently validate the integrity of certain file in certain loading processes, successful exploit could allow the attacker to load a crafted file to the device through USB.Affected product versions include:OSCA-550 versions 1.0.1.23(SP2);OSCA-550A versions 1.0.1.23(SP2);OSCA-550AX versions 1.0.1.23(SP2);OSCA-550X versions 1.0.1.23(SP2).
