Descriptions

An issue was discovered in the LINE jp.naver.line application 8.8.0 for iOS. The LAContext class for Biometric (TouchID) validation allows authentication bypass by overriding the LAContext return Boolean value to be "true" because the kSecAccessControlUserPresence protection mechanism is not used. 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 iOS devices on which a jailbreak has occurred

** EN DISPUTA ** Se ha descubierto un problema en la aplicación LINE jp.naver.line 8.8.0 para iOS. La clase LAContext para la validación biométrica (TouchID) permite la omisión de autenticación sustituyendo el valor boleano de retorno de LAContext por "true" dado que el mecanismo de protección kSecAccessControlUserPresence no se utiliza. En otras palabras, un atacante podría autenticarse con una huella digital arbitraria. NOTA: el fabricante indica que esto no es un ataque de interés en el contexto del modelo de amenazas, lo que excluye a los dispositivos iOS que tienen jailbreak.
