Descriptions

The Toyoko Inn official App for iOS versions prior to 1.13.0 and Toyoko Inn official App for Android versions prior 1.3.14 don't properly verify server certificates, which allows a man-in-the-middle attacker to spoof servers and obtain sensitive information via a crafted certificate.

La aplicación oficial de Toyoko Inn para versiones de iOS anteriores a 1.13.0 y la aplicación oficial de Toyoko Inn para versiones de Android anteriores a 1.3.14 no verifican correctamente los certificados del servidor, lo que permite a un atacante intermediario falsificar servidores y obtener datos e información confidencial a través de un certificado elaborado.
