CVE-2019-12813

Estado: ModificadaMedia (5.9)—

Se ha descubierto un problema en el Digital persona U.are U 4500 Fingerprint Reader v24. La llave y salt utilizado para alterar la imagen de la huella digital muestra un texto claro cuando el dispositivo del escáner de huellas digitales transfiere una imagen de la huella digital al controlador. Un atacante que olfateé una imagen de huella digital cifrada puede descifrar fácilmente esa imagen usando la clave y la sa
