Descriptions

An issue was discovered in the org.telegram.messenger application 4.8.11 for Android. The FingerprintManager class for Biometric validation allows authentication bypass through the callback method from onAuthenticationFailed to onAuthenticationSucceeded with null, because the fingerprint API in conjunction with the Android keyGenerator class is not implemented. In other words, an attacker could authenticate with an arbitrary fingerprint. NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes Android devices on which rooting has occurred

** EN DISPUTA ** Se ha descubierto un problema en la versión 4.8.11 de la aplicación org.telegram.messenger para Android. La clase FingerprintManager para la validación biométrica permite la omisión de autenticación mediante el método callback desde onAuthenticationFailed a onAuthenticationSucceeded con un null. Esto se debe a que la API fingerprint no está implementada junto con la clase de Android keyGenerator. En otras palabras, un atacante podría autenticarse con una huella dactilar arbitraria. NOTA: el fabricante indica que este no es un ataque de interés en el contexto de su modelo de amenazas, que excluye a los dispositivos Android rooteados.
