"value": "An issue was discovered in the com.getdropbox.Dropbox app 100.2 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"

La clase LAContext para la validaci\u00f3n biom\u00e9trica (TouchID) permite la omisi\u00f3n de autenticaci\u00f3n reemplazando el valor boleano de retorno de LAContext para que sea \"true\" debido a que no se emplea el mecanismo de protecci\u00f3n kSecAccessControlUserPresence. En otras palabras, un atacante podr\u00eda autenticarse con una huella dactilar arbitraria. NOTA: el fabricante indica que este no es un ataque de inter\u00e9s en el contexto de su modelo de amenazas, que excluye a los dispositivos iOS con jailbreak."
